[0030] A fixing groove 41 is fixedly provided on the outer wall of the upper end of the fixed arc plate 39. The opening and closing plate 40 includes an arc opening and closing plate 42 and a rotating and interlaced horizontal axis 43.

[0031] During specific use, the mounting base plate 11 of the device of the present invention is fixed and installed according to actual usage requirements through the mounting bolts and nuts on the bottom, and then the external power supply is connected. The end drive ring 33, the end adsorption head 35 and the toggle switch 37 in the one-way fitting push member 2 are connected to the power supply. The end adsorption head 35 is in an adsorption state under normal circumstances, the end adsorption head 35 adsorbs the sliding groove member 9, and the toggle switch 37 is connected to the end adsorption head 35 signal.

[0032] The operator then opens the opening and closing plate 40 and inserts the binding into the fixing groove 41 of the fixed arc plate 39 to fix the arc opening and closing plate 42. The operator then holds the toggle switch 37, and the end suction head 35 stops sucking the sliding groove 9. By toggling the toggle lever 36, the position of the extension rod 34 is changed.

The anti-slip strip on the active roller 31 is used to increase the friction between the active roller 31 and the cable shell, pushing the cable for transfer. Under the mutual influence of the friction, the radial contact plate 1 When the edge portion of 9 is in contact with the cable, it drives the fixed wrapping ring 18 and the follow-up rotating shell 13 to rotate, the follow-up main shaft 16 drives the pad 20 to rotate, the ratchet ring 21 rotates in the ratchet wrapping ring 25, and the snap ring 23 rotates in the snap groove 26 of the wrapping shell 24 to prevent the wrapping shell 24 and the end rotating head 17 from slipping. The outer wall of the insertion shaft 27 is fixedly connected to the inner wall of the inner ring of the contact bearing 22, thereby increasing the rotational lubrication between the end rotating head 17 and the one-way rotation control component 5. When special circumstances occur, such as when the traction speed changes or the power is cut off, the cable is retracted under the action of inertia. At this time, when the ratchet ring 21 rotates in the opposite direction with the follow-up rotating shell 13 and the follow-up main shaft 16, the ratchet wrapping ring 25 restricts the ratchet ring 21 to prevent the one-way rotating part 14 from rotating in the opposite direction, thereby preventing the cable from being retracted.

[0033] The above is the overall workflow of the present invention. Just repeat this step next time you use it.
