[0051] The device is provided with two symmetrically arranged arc-shaped clamping plates 24 and anti-skid pads 25, which can clamp and fix the cable using the arc-shaped clamping plates 24 and anti-skid pads 25, thereby avoiding damage caused by sliding friction between the cable and the inner wall of the plate 7 and the connecting plate 10, thereby increasing the service life of the cable.
