[0022] In the embodiment, a sliding groove is arranged on the inner side wall of the insertion hole, a sliding block 7 is slidably connected to the inner side wall of the sliding groove, and the sliding block 7 is used to drive the limiting rod 5 to move. The upper end of the sliding block 7 is fixedly connected to a vertically arranged limiting rod 5, which is used to cooperate with the limiting nut 3 to prevent the limiting nut 3 from loosening. The lower end of the limiting nut 3 is annularly distributed with a plurality of limiting grooves corresponding to the limiting rod 5. The upper end of the limiting rod 5 slidably penetrates the clamping block 2 and extends into the limiting groove. A chamfer is arranged on the upper end of the limiting rod 5 and close to the edge, which is used to facilitate the insertion of the limiting rod 5 into the limiting groove. A fixing ring 6 is fixedly sleeved with the lower end of the limiting rod 5, which is used to improve the firmness of the lower end of the limiting rod 5. The lower end of the fixing ring 6 is fixedly connected to the upper end of the sliding block 7.
