(23) With reference to FIG. 5, the first base 100 is provided with the chamber 110. An opening 120 is formed on each of two opposite side walls of the chamber 110. An end surface of the first base 100 which is close to the rail 800 is further provided with a first hooking part 130 for hooking the rail 800. In this embodiment, each of the openings 120 is elongated in shape; each of the openings 120 has a longitudinal direction which is parallel to a longitudinal direction of a first elastic member (140); each of the openings 120 has a width which is greater than a height of a connecting rod which is used to connect a first adjusting part 230 and a first connecting part 210, so that when the first adjusting part 230 is pressed, the movable pull rod 200 can rotate.

(24) With reference to FIGS. 7, 8 and 10, the movable pull rod 200 comprises the first connecting part 210, a second hooking part 220 connected to the first connecting part 210 for hooking the rail 800, and the first adjusting part 230 connected to the first connecting part 210. The second hooking part 220 passes through the opening 120 on one of the side walls of the chamber 110 to be disposed outside the chamber 110. The first adjusting part 230 passes through the opening 120 on the other side wall of the chamber 110 to be disposed outside the chamber 110. The first connecting part 210 is fixed to an inner wall of the chamber 110 through a first elastic member 140, so that the first hooking part 130 and the second hooking part 220 form a clamping device for fixing first base 100 and the rail 800. The first connecting part 210 is further provided with teeth 240. A rack 300 is provided with rack teeth 310. The teeth 240 and the rack teeth 310 cooperate to fix the movable pull rod 200 and the rack 300. An end surface of the first connecting part 210 distant from the rack teeth 310 is an inclined surface. A guide pin 160 is provided in the chamber 110. The first elastic member 140 has a first end which is fixed to the guide pin 160 and a second end which is fixed to the first connecting part 210. The first adjusting part 230 has a side wall which is evenly provided with strip-shaped protrusions 231. The strip-shaped protrusion 231 can increase the friction force generated by the contact between the hand and the first connecting part 210, thereby achieving an anti-slip effect. In this embodiment, the first elastic member 140 is a spring.

(25) With reference to FIG. 6, the second base 400 has a first end surface which is fixed to the tactical light 900 and a second end surface which is fixed to the first base 100. The first end surface and the second end surface of the second base 400 face each other. In this embodiment, a fixing block is provided on an end surface of the tactical light 900 which is close to the second base 400. The fixing block is provided with a threaded hole, and the tactical light 900 is fixed to the second base 400 by screw connection.

(26) With reference to FIG. 4, in this embodiment, hook legs 221 are provided on the first hooking part 130 and the second hooking part 220, and the hook leg 221 of the first hooking part 130 and the hook leg 221 of the second hooking part 220 are arranged in opposite direction. When the first base 100 is fixed to the rail 800, inner side walls of the hook legs 221 are respectively in contact with a side wall of the first elongated slot 700. At this time, the spring has not been deformed or compressed. In this embodiment, the first hooking part 130 and the second hooking part 220 are both bent away from the opening 120. In other embodiments, the first hooking part 130 and the second hooking part 220 are both bent towards the opening 120. At this time, the spring is initially in a stretched state.

(27) With reference to FIGS. 12 and 13, the spring is in a non-deformed or compressed state. During mounting, a clockwise force is applied to the first adjusting part 230. While the force is applied, the spring is deformed in a vertical direction, so that the first adjusting part 230 can rotate clockwise. The first adjusting part 230 drives the first connecting part 210 to rotate clockwise so that the teeth 240 are disengaged from the rack teeth 310. At this time, the movable pull rod 200 can move in the chamber 110. Then, pull the first adjusting part 230, thereby compressing the spring, and the movable pull rod 200 then moves towards the guide pin 160; the first hooking part 130 is hooked with the side wall of the first elongated slot 700 of the rail 800. The second hooking part 220 is inserted in the first elongated slot 700; then release the first adjusting part 230. When the spring is not fully restored to the initial state, the second hooking part 220 abuts against the side wall of the first elongated slot 700, thereby enabling the first hooking part 130 and the second hooking part 220 to clamp the rail 800 so as to fix the first base 100 to the firearm rail. When stop applying the force to the first adjusting part 230, the spring restores to its initial form in the vertical direction; the teeth 240 are then engaged with the rack teeth 310 on the rack 300 to fix the movable pull rod 200 to the rack 300. During detachment, a clockwise force is applied to the first adjusting part 230, and the teeth 240 are disengaged from the rack teeth 310; then pull the first adjusting part 230 and slide the first base 100 so that the side wall of the rail 800 no longer abuts against the first hooking part 130 and the second hooking part 220, then the first hooking part 130 and the second hooking part 220 are removed from the firearm rail to achieve detachment of the first base 100 from the rail 800.

(28) The spring is in a stretched state. During mounting, the first hooking part 130 is hooked with the side wall of the first elongated slot 700 of the rail 800; then a clockwise force is applied to the first adjustment part 230. At the same time when the force is applied, the spring deforms in the vertical direction, so that the first adjusting part 230 can rotate clockwise; the first adjusting part 230 drives the first connecting part 210 to rotate clockwise so that the teeth 240 are disengaged from the rack teeth 310. When the spring is not fully restored to the initial state, the inner side of the hook leg of the second hooking part 220 abuts against the side wall of the first elongated slot 700, thereby enabling the first hooking part 130 and the second hooking part 220 to clamp the rail 800 so as to fix the first base 100 to the firearm rail. When stop applying the force to the first adjusting part 230, the spring restores its initial form in the vertical direction; the teeth 240 are then engaged with the rack teeth 310 on the rack 300 to fix the movable pull rod 200 to the rack 300. During detachment, in contrast with the detachment method when the spring is in a non-deformed or compressed state, after the teeth 240 are disengaged from the rack teeth 310, pull the movable pull rod 200 so that the spring in a stretched state until the side wall of the rail 800 no longer abuts against the first hooking part 130 and the second hooking part 220, then the first hooking part 130 and the second hooking part 220 are removed from the firearm rail to achieve detachment of the first base 100 from the rail 800.

(29) With reference to FIGS. 9 and 11, in this embodiment, the locking device for the tactical light 900 further comprises a lever 500 rotatably connected to the first base 100. The lever 500 comprises a second connecting part 510, a third hooking part 520 extending from a first end of the second connecting part 510, a third connecting part 530 disposed between the second connecting part 510 and the third hooking part 520, and a second adjusting part 540 extending from a second end of the second connecting part 510. The third connecting part 530 is connected to the inner wall of the chamber 110 through a shaft pin 550, so that the lever 500 is rotatably connected to the first base 100. A slot 170 is formed on a side wall of the first base 100 which extends along a stretching direction of a second elastic member 150; the second connecting part 510 is fixed to the inner wall of the chamber 110 through the second elastic member 150. Specifically, the second connecting part 510 is fixed to a bottom wall of the chamber 110 through the second elastic member 150. The third hooking part 520 is fixed to the second base 400. The second adjusting part 540 passes through the slot 170 to be disposed outside the chamber 110. The slot 170 is further provided with a second elongated slot along a vertical moving direction of the second adjusting part 540, so that the second adjusting part 540 can move with the compression of the second elastic member 150. The first end and the second end of the second connecting part 510 face each other. In this embodiment, the second elastic member 150 is a spring. In other embodiments, a tension spring can also be used instead of the spring. At this time, the second connecting part 510 is connected to a top wall of the chamber 110 through the second elastic member 150. When the third hooking part 520 abuts against the sliding platform 410, the tension spring is in a stretched state.

(30) With reference to FIG. 6, in this embodiment, the second end surface of the second base 400 is provided with two sliding platforms 410, and the first base 100 is correspondingly provided with a sliding slot 180. The sliding platforms 410 are inserted in the sliding slot 180. The sliding platforms 410 cooperate with the sliding slot 180 so that the second base 400 can move relative to the first base 100. The third hooking part 520 hooks a side wall of one of the sliding platforms 410, so that the second base 400 can be fixed with the first base 100.

(31) With reference to FIG. 11, when mounting the tactical light 900, a force is applied to the second adjusting part 540, which causes the spring on the second adjusting part 540 to compress; at this time, the third hooking part 520 moves away from the sliding slot 180. Then, align the sliding platforms 410 with the sliding slot 180, and then push the second base 400 so that the second base 400 is completely inserted to the first base 100. The second adjusting part 540 is then loosened, and the second elastic member 150 restores to its initial state. At this time, the inner side wall of the third hooking part 520 abuts against the side wall of one of the sliding platforms 410 to fix the second base 400 to the first base 100. During detachment, a force is applied on the second adjusting part 540 to compress the spring on the second adjusting part 540. At this time, the third hooking part 520 is detached from the side wall of the sliding platform 410, and the third hooking part 520 no longer abuts against the sliding platform 410. Then, push the second base 400 in the opposite direction to disengage the second base 400 from the first base 100.

(32) With reference to FIGS. 2 and 16, in this embodiment, a side block 600 is fixed in the chamber 110, and a recess 610 is provided on an end surface of the side block 600 which is close to the first connecting part 210. The recess 610 has a shape which corresponds to that of the side block 600.

(33) With reference to FIGS. 14 and 15, a rail 800 is provided with the first elongated slots 700 on the end surface of the rail 800 which is close to the first hooking part 130. In other embodiments, through holes 810 may be provided instead of the first elongated slots 700. In this embodiment, there are a plurality of first elongated slots 700. In other embodiments, there can be only one first elongated slot 700. The quantity and shape of the first elongated slot 700 are determined according to the distance between the first hooking part 130 and the second hooking part 220, which only needs to ensure that the second hooking part 220 can abut against the side wall of the first elongated slots 700 to fix the first base 100 and the rail 800.

(34) The above embodiment is only one of the preferred embodiments of the present invention. General changes or replacements made by a person skilled in this field of art in accordance with the scope of teachings of the present invention should also fall within the scope of protection of the present invention.
