In the process of movement, one end of the cable body 11 will be subjected to force, so that the cable body 11 drives the winding drum 403 to rotate, so that the cable body 11 releases the wire outside the winding drum 403, so that the cable body 11 is laid in the cable trough.

[0022] In the case implementation, the lifting structure 5 includes a mother rod 501, a motor 502, a threaded rod 503, a movable plate 504, a slider 505, a slide groove 506 and a sub-rod 507.

[0023] When implementing, follow these steps:

[0024] 1) First, fix one end of the cable body 11 to the winding turntable 3, and pass it through roller 1 8 and roller 2 9;

[0025] 2) Then, the motor 2 502 moves forward to drive the threaded rod 503 to rotate, and the movable plate 504 rises with the rotation of the threaded rod 503, and the top plate 6 rises, so that the arc tube 10 corresponds to the cable trough, and the four universal wheels 2 are rotated by pushing the push handle 3, so as to push the device to move;

[0029] In addition, by setting up a lifting structure 5, the movement of motor 2 502 drives the threaded rod 503 to rotate, and the movable plate 504 rises or falls with the rotation of the threaded rod 503. The movable plate 504 drives the top plate 6 to rise or fall through the sub-rod 507, thereby solving the problem in the Chinese utility model with patent number CN209823373U that when the cable is used up, the device will be pulled, causing damage to the device and reducing the life of the device.
