The second arc-shaped limit frame 26 can move up and down through the elastic component 27, so that it can be adjusted according to the thickness of the cable.

[0054] After the cable is wound around the sleeve 35, when the sleeve 35 is to be removed, the first drive device 5 and the second drive device 20 are turned off, and then the left and right telescopic devices 7 are contracted to the left to move the fixed shaft 6 to the left, and the left and right ends of the connecting plate 9 are respectively rotated in the opposite direction about a tangent line tangent to the fixed shaft 6 to pull the arcuate side plate 8 inward and separate it from the inner wall of the sleeve 35, so that it is no longer tightly fitted with the inner wall of the sleeve 35 and the sleeve 35 is no longer fixed. In this process, the slide rod 10 is driven to slide in the radial direction of the rotating column 4, and then the sleeve 35 can be moved to the right to be removed from the arcuate side plate 8.

[0055] Therefore, the utility model is easy, fast and safe to operate, and the cable can be quickly and conveniently wound around the sleeve. After the cable is wound around the sleeve, the sleeve can be conveniently removed, thereby improving work efficiency and solving the problem that the existing cable pulling device is inconvenient to remove the cable after it is wound around the sleeve.

[0056] In summary, the cable pulling device of the utility model can wind the cable around the sleeve and easily remove it, thereby improving work efficiency and being suitable for large-scale promotion and application.

[0057] It can be seen that the purpose of the utility model has been completely and effectively achieved. The function and structural principle of the utility model have been demonstrated and explained in the embodiments. Without departing from the principles, the implementation methods can be modified arbitrarily. Therefore, the utility model includes all modified implementation methods based on the spirit and scope of the claims.
