DETAILED DESCRIPTION OF THE INVENTION

[0019] As shown in FIGS. 1 to 3, movable equipment 30 is a linear mover or a rotary mover. In the present embodiment, the movable equipment 30 is preferably the linear mover. The linear mover is an air spring that is maintained in an on state all the time. A locking mechanism 80 is mounted on a power output portion 31 of the movable equipment 30. The power output portion 31 may be a cylinder portion of the movable equipment 30 or a piston rod portion of the movable equipment 30. In the present embodiment, the power output portion 31 is preferably the cylinder portion of the movable equipment 30, that is, the cylinder portion is a movable portion, while the piston rod portion is fixed. The locking mechanism 80 limits the displacement of the power output portion 31 of the movable equipment. The locking mechanism 80 includes: a first torsion spring 81, a first connection assembly and a switch 85. The first torsion spring 81 enclasps the power output portion 31 of the movable equipment 30.

[0020] As shown in FIGS. 1 to 3, one end 81a of the first torsion spring 81 is fixed with the first connection assembly. The first connection assembly includes a first sleeve 82 and a first fixed seat. The first sleeve 82 is arranged on the power output portion 31 of the movable equipment 30 in a sleeving manner. One end of the first sleeve 82 is provided with a first opening. One end 81a of the first torsion spring 81 is clamped in the first opening. The first fixed seat is fixedly connected with the first sleeve 82. The first fixed seat 83 is connected with a fixing member (not shown in the figures). The first fixed seat includes a body 83 and a casing 84. The body 83 is fixed with the casing 84. The first sleeve 82 is fixed with the casing 84. The first fixed seat may also include only the body 83, and the body 83 is directly fixed with the first sleeve 82.

[0021] As shown in FIGS. 1 to 3, the switch 85 is fixed with the other end 81b of the first torsion spring 81. When the switch 85 is rotated, the first torsion spring 81 is twisted, and a diameter of an inner hole of the first torsion spring 81 is increased to release the locking of the power output portion 31 of the movable equipment 30.

[0022] As shown in FIGS. 1 to 3, the locking mechanism 80 further includes a second torsion spring 86 and a second connection assembly. The second torsion spring 86 enclasps the power output portion 31 of the movable equipment 30. One end 86a of the second torsion spring 86 is fixed with the second connection assembly, and the other end 86b of the second torsion spring 86 is fixed with the switch 85. When the switch 85 is rotated, the second torsion spring 86 is twisted, and a diameter of an inner hole of the second torsion spring 86 is increased to release the locking of the power output portion 31 of the movable equipment 30. The first torsion spring 81 and the second torsion spring 86 are oppositely twisted, so that the first torsion spring 81 and the second torsion spring 86 may be simultaneously twisted by the same switch 85, and may be simultaneously reset.

[0023] As shown in FIGS. 1 to 3, the second connection assembly includes a second sleeve 87 and a second fixed seat 83a. The second sleeve 87 is arranged on the power output portion 31 of the movable equipment 30 in a sleeving manner. One end of the second sleeve 87 is provided with a second opening. One end of the second torsion spring 86 is clamped in the second opening. The second fixed seat 83a is fixedly connected with the second sleeve 87. The second fixed seat 83a is connected with a fixing member (not shown in the figures). The second fixed seat 83a is arranged on the casing 84 in a sleeving manner and fixed with the casing 84.

[0024] As shown in FIGS. 1 to 3, an unlocking mechanism 100 drives the locking mechanism 80 to be separated from the power output portion 31 of the movable equipment 30 in a cooperative manner, and the unlocking mechanism 100 is connected with the locking mechanism 80. The unlocking mechanism 100 includes a pressure plate mechanism and a cable. The pressure plate mechanism is connected with one end of the cable. The other end of the pressure plate mechanism is connected with the switch 85. The pressure plate mechanism works to drive the cable to move, and the cable drives the switch 85 to rotate, thereby driving the first torsion spring 81 and the second torsion spring 86 to be twisted to release the locking of the power output portion 31 of the movable equipment 30.

[0025] The present utility model is not limited to the above embodiment. For example, when the movable equipment 30 is the linear mover, the linear mover may also be an air cylinder, a hydraulic cylinder and the like. As the rotary mover, the movable equipment 30 may be, for example, a ring-like component or a gear, and at the moment, the locking mechanism may be of an arc shape.
