[0027] It also includes a bolt assembly, the bolt assembly includes a bolt with a screw rod 1 and a screw head 2, the screw rod 1 is threadedly connected with a nut 3, and the nut 3 is hexagonal or circular. After tightening, it is tightly pressed against the side surface of the long piece 8, fixing the position of the bolt.

[0028] It also includes a fixed tube 4, which is a hollow tubular component. The side wall of the fixed tube 4 is provided with a through hole 5 connected with the screw rod 1. The through hole 5 is matched with the diameter of the screw rod 1, ensuring the accurate penetration of the screw rod 1. The fixed tube 4 is threadedly connected with a positioning pin 6. The inner wall of the tube is provided with internal threads. The end surface of the positioning pin 6 is provided with a hexagonal operating groove, which is convenient for tool tightening. The screw rod 1 is provided with a positioning groove 7 corresponding to the positioning pin 6.
