The movement of the third pulley 6 on the mounting plate 2 is restricted by the installed limiting slide post 7, so that the swing of the third pulley 6 is more stable. A telescopic motor 9 located in front of the arc groove 8 is rotatably installed on the front side of the mounting plate 2. The telescopic end of the telescopic motor 9 is rotatably connected to the back of the connecting arm 5.

[0026] The working principle of the above embodiment is:

[0027] When repairing the cable winding, first pass the optical cable from the top of the No. 1 pulley 3 and the No. 2 pulley 4 into the space between the two connecting arms 5, and then wrap it around the top of the No. 4 pulley 10 from the bottom of the No. 3 pulley 6, and then connect the passed optical cable to the external winder. The DC motor 12 drives the active gear 13 to rotate, driving the No. 4 pulley 10 inside the driven gear 11 to rotate, so that the optical cable can be pulled and transported outward. At this time, the telescopic motor 9 is unfolded to push the No. 3 pulley 6 on the two connecting arms 5 to rotate clockwise, so as to press the optical cable, thereby increasing its tension. When the telescopic motor 9 is retracted and pulls the No. 3 pulley 6 on the two connecting arms 5 to rotate counterclockwise, the pressure on the optical cable can be reduced. At this time, the tension of the optical cable becomes smaller. After use, the device can be transferred by holding the two lifting handles 101.
