A screw rod hole connected to the axial hole is provided in the middle of the adjustment plate. The screw rod is installed inside the bearing. One end of the screw rod is threadedly connected to the screw rod hole, and the other end is arranged outside and fixedly connected to the handwheel.

[0007] As a preferred technical solution, a slide groove is vertically provided on the inner wall surface of the adjustment plate, and a slider is installed on the inner wall surface of the adjustment cavity opposite to the slide groove, and the slider is slidably arranged in the slide groove.

[0008] As a preferred technical solution, a notch is provided on one side of the gear facing the outer opening of the wiring groove.

[0009] As a preferred technical solution, the cross-sections of the connecting grooves are all arranged in a circular structure, the cross-sections of the wiring tubes are all arranged in a circular structure, and the width of the wiring groove opening is smaller than the diameter of the wiring tube.

[0010] As a preferred technical solution, both ends of the wiring groove are provided with guide parts.

[0011] The beneficial effects of the utility model are as follows: the utility model has a simple structure, and there is no need to check whether the two ends of the wiring harness are connected.
