After the locking handle 3 is rotated to the right position, the pushing block 18 is pushed downward to compress the second spring 17. After the second hook 16 moves to the bottom of the first hook 15, the pushing block 18 is released. The second hook 16 moves upward under the elastic force of the second spring 17 to hook the first hook 15, and the locking device is locked; when unlocking is required, the pushing block 18 is pushed downward to compress the second spring 17, and the second hook 16 leaves the first hook 15, and the unlocking of the locking device is completed. At this time, the locking handle 3 can be rotated. The structure is simple, easy to install, the locking is firm and reliable, and the operation is simple and convenient.

[0045] Furthermore, the connecting block 20 is mounted on the mounting plate 19 by screws, the first hook 15 is mounted on the lower connecting portion 12 by screws, and the second hook 16 and the mounting plate 19 are an integrated structure.

[0046] Preferably, the left side of the left joint 1 and the right side of the right joint 2 are respectively fixedly connected with wear-resistant plates 21, and the protrusion 7 on the left side of the left joint 1 is arranged on the corresponding wear-resistant plate 21 and is located on the side of the wear-resistant plate 21 away from the left joint 1; the protrusion 7 on the right side of the right joint 2 is arranged on the corresponding wear-resistant plate 21 and is located on the side of the wear-resistant plate 21 away from the right joint 2. The materials of the left joint 1 and the right joint 2 are metal, and the material of the wear-resistant plate 21 is plastic, and the wear-resistant plate 21 is fixedly installed on the corresponding joints by screws. The left joint 1 and the right joint 2 made of metal are easy to wear. By setting the wear-resistant plate 21, the wear of the left joint 1 and the right joint 2 can be effectively prevented, and at the same time, the protrusion 7 is easy to be processed on the wear-resistant plate 21 made of plastic.
