Regarding the technical means adopted by the present invention in order to achieve the above-mentioned purposes and effects, a preferred and feasible embodiment is presented, and shown in the drawings. The details are as follows: For the embodiment of the present invention, please refer to the second figure. As shown, it is mainly composed of a housing 1, a lock core 2, a locking hook 3, and a bottom plate 4. The housing 1 is provided with an insertion hole 10 on one side, and the other side of the housing 1 is provided with a chamber 11. The chamber 11 is provided with a lock core groove 12, a lock buckle groove 13, a front lock hook channel 14 and an engaging portion 15. The engaging portion 15 is used as a leg; the lock core 2 is assembled in the housing 1 In the lock core groove 12, the lock core 2 is provided with a lock hole 20 in the front, and the lock core 2 is provided with a convex shaft 21 in the rear. The convex shaft 21 is set as a non-circular body; the lock hook 3 is assembled in The housing 1 locks the hook channel 14 in front and is fixed to the convex shaft 21 of the lock core 2. One end of the lock hook 3 is provided with a shaft hole 30, and the shaft hole 30 is set as a non-circular body; the bottom plate 4 is Assembled in the containing chamber 11 of the shell 1 and fixed to the joint 15 of the shell 1, a movable space 40, a rear lock hook channel 41 and a docking portion 42 are provided on one side of the bottom plate 4. The docking portion 42 The system is set as a button hole, and one end of the bottom plate 4 is provided with a lock button hole 43.

When assembling, please refer to the second to fourth drawings. First, set the lock core 2 in the lock core groove 12 of the housing 1 so that the lock hole 20 of the lock core 2 corresponds to the receptacle of the housing 1 10. Set the lock hook 3 in the front lock hook channel 14 of the housing 1, and the shaft hole 30 of the lock hook 3 is correspondingly engaged and fixed to the convex shaft 21 of the lock core 2, and then the bottom plate 4 is assembled The accommodating chamber 11 is arranged in the housing 1, so that the rear lock hook channel 41 of the bottom plate 4 corresponds to the front lock hook channel 14 of the housing 1, and the butting portion 42 of the bottom plate 4 is correspondingly engaged and fixed to the joint of the housing 1 The part 15 is fixed in such a way that the mating part 42 (buckle hole) is directly buckled to the joint part 15 (leg), and it can also be fixed by riveting, screwing or welding. The lock core 2 can control the lock The hook 3 moves on the front lock hook channel 14, the rear lock hook channel 41 and the movable space 40; in this way, the entire assembly can be completed.
