DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Embodiment 1, by Figure 1-Figure 4 The utility model comprises a first lock body 1 and a second lock body 2 which are arranged opposite to each other. A fixed hook 3 is connected to the side opposite to the first lock body 1 and the second lock body 2. A first bottom cover 4 is movably connected to the lower end of the first lock body 1. A second bottom cover 5 is movably connected to the lower end of the second lock body 2. A slider 6 is slidably arranged inside the second lock body 2. A movable hook 7 is connected to one end of the slider 6. The movable hook 7 is movably connected to the fixed hook 3.

[0023] A rotating rod 8 is provided on one side of the upper end of the second lock body 2, and a movable knob 9 is connected to the upper end of the rotating rod 8. A retaining spring 10 is provided on the outer side of the rotating rod 8 to limit the position of the second lock body 2. A gear 11 is connected to the lower end of the rotating rod 8. A tooth 12 is provided on one side of the slider 6, and the gear 11 is meshed with the tooth 12.

[0024] A guide rod 13 is connected to one side of the inner wall of the second lock body 2, and a slide groove 14 is provided at one end of the slider 6, and the slide groove 14 is slidably matched with the guide rod 13;

[0025] A limiting rod 15 is connected to one side of the inner wall of the second lock body 2, and a limiting groove 16 is formed at one end of the slider 6, and the limiting rod 15 is located in the limiting groove 16;

[0026] A first positioning rod 17 is provided on one side of the inner wall of the second lock body 2, a second positioning rod 18 is connected to one end of the slider 6, and a tension spring 19 is provided between the second positioning rod 18 and the first positioning rod 17;
