An opening 13 can be formed between the lower end of the blocking section 12 and the question mark-shaped body 11. The lower end of the movable bolt 2 may be hinged at the lower end of the question mark-shaped body 11, and a reset device 3 is provided between the movable bolt 2 and the question mark-shaped body 11. The upper end of the movable bolt 2 may be elastically contacted with the upper end of the question mark-shaped body 11, and the receiving cavity 4 can be formed between the movable bolt 2 and the question mark-shaped body 11, and the blocking section 12 may be located outside the receiving cavity 4.

(10) Referring specifically to FIG. 5, the question mark-shaped body 11 and the blocking section 12 may be of integrated structure, and the question mark-shaped body 11 may include a curved section 111 at its upper end, an inclined section 112 at its middle part, and a vertical section 113 at its lower end. Inclined elongated spaces 114 may be formed between the blocking section 12 and the curved section 111, or formed between the blocking section 12 and the inclined sections 112. The vertical length of the elongated space is larger than the lateral width thereof, and the opening 13 and the receiving cavity 4 may be both part of the elongated space 114.

(11) Moreover, the upper end of the blocking section 12 and the upper end of the question mark-shaped body 11 may be smoothly transitionally connected, and the middle part of the blocking section 12 may be curved toward the direction of the question mark-shaped body 11, and the lower end of the blocking section 12 may be curved away from the direction of the question mark-shaped body 11. In the present embodiment, the upper end of the blocking section 12 and the curved section 111 may be smoothly transitionally connected, the middle of the blocking section 12 is curved toward the direction of the inclined section 112, and the lower end of the blocking section 12 is curved away from the blocking section 112. Surely, there may be other cases where, for example, the middle portion of the blocking section 12 is curved toward the direction of the vertical section 113, and the lower end of the blocking section 12 is curved away from the vertical section 113.

(12) Thus, the buckle is introduced into the receiving cavity 4 in the direction, the opening 13 is large at the proximal end and small at the distal end, so that the buckle is facilitated to insert into the opening at the proximal end, and then it can reduce the probability of the buckle sliding out of the opening 13 from the receiving cavity 4 at the distal end. Moreover, the lower end of the blocking portion 12 may be curved away from the question mark-shaped body 11, and the buckle can be better prevented from sliding off the hook-shaped buckle body 1.

(13) Referring to FIG. 4 for further details, the upper end of the movable bolt 2 may be curved toward the upper end of the question mark-shaped body 11 to form a barrier section 25, and one end of the barrier section 25 may be elastically contacted with the curved section 111, and the barrier section 25 and the curved section 111 are mutually perpendicular to each other at the contact point. The movable bolt 2 may include a bolt body 21 and a limiting block 22 provided at an upper end of the bolt body 21. The lower end of the bolt body 21 may be hinged with the question mark-shaped body 11, and the upper end of the bolt body 21 is the barrier section 25 designed such that when the buckle is applied with force toward the movable bolt 2 from the contact position of the movable bolt 2 and the hook-shaped buckle body 1 in the receiving cavity 4, the direction of the thrust is always directed toward the near direction pushing the movable bolt 2 toward the hook-shaped buckle body 1. That is, the direction of the thrust is directed toward the locking direction of the movable bolt 2, the buckle can not extrude the movable bolt 2, which can effectively prevent the buckle from disengaging the buckle structure.

(14) Referring to FIG. 6 and FIG. 7, the limiting block 22 may be connected to the side of the bolt body 21 adjacent to the question mark-shaped body 11. Specifically, the limiting block 22 is connected to the bolt body 21 at the side adjacent to the inclined section 112.
