The clamping screw 9 passes through the threaded hole to drive the arc-shaped clamping plate 8 to move up and down. The height of the arc-shaped clamping plate 8 can be adjusted by turning the knob to tighten the screw 9, and the cable 13 placed in the inner circle formed by the upper fixing frame 1 and the lower fixing frame 2 can be pressed tightly. The outer side of the bottom end of the lower fixing frame 2 is provided with a convex seat 10 with a circular hole, and the outer periphery of the interconnector 12 is provided with a circular hole, and the pull rope 11 connects the circular hole of the convex seat 10 with the circular hole of the interconnector 12.
