[0022] Please refer to Figure 3 Self-locking assembly includes base 7, the bottom of base 7 is fixedly connected with fixed arm 8, the other end of fixed arm 8 is hinged with hinged arm 9, the other end of hinged arm 9 is rotatably connected with roller 10, hinged arm 9 is rotatably connected with moving seat 11, the top surface of moving seat 11 is fixedly connected with first spring 12, the other end of first spring 12 is fixedly installed at the bottom of base 7, pressure rod 13 is sleeved in first spring 12, the top end of pressure rod 13 is fixedly installed at the bottom of base 7, the other end of pressure rod 13 penetrates moving seat 11 and can abut on roller 10.

[0023] The jacking force of the first spring 12 is slightly greater than the weight of the bottom plate 1, and in the case of no load, the roller can be freely rolled, and the pulling device can be transferred. When the wire roller is placed on the bottom plate 1, the bottom plate 1 starts to press down on the first spring 12, the roller 10 drives the hinged arm 9 to rotate upward along one end of the hinged arm 9, so that the moving seat 11 moves upward, and in the process of upward movement of the moving seat 11, the pressure rod 13 gradually approaches the roller 10 and abuts against the surface of the roller 10, and the pressure rod 13 starts to lock the roller 10, realizing the overall fixation of the pulling device.

[0024] Referring to Figure 2 , the bottom plate 1 is provided with a first sliding groove 14, and the inner side wall of the first sliding groove 14 is rotatably connected with a threaded rod 15. The two moving blocks 2 are threadedly installed on the threaded rod 15. The inner side wall bottom of the first sliding groove 14 is fixedly connected with a double-shaft motor 16. The driving end of the double-shaft motor 16 is fixedly connected with the end of the threaded rod 15 away from the inner side wall of the first sliding groove 14. The threaded rod 15 is driven to rotate by the double-shaft motor 16, realizing the opposite movement of the two groups of moving blocks 2 in the first sliding groove 14, thereby driving the fixed plate 3 to quickly and stably clamp and fix the wire roller. This design not only simplifies the cumbersome steps of traditional manual clamping, but also greatly improves the clamping efficiency and accuracy. At the same time, the user only needs to simply pull the cable to complete the pulling operation, which is simple and convenient to operate, and improves the work efficiency.
