[0007] Preferably, the inner diameter of the fixing hole is larger than the inner diameter of the screw hole, so that after the rod body contacts the connecting shaft through the screw hole, it can continue to move without contacting the inner wall of the fixing hole.

[0008] Preferably, the movable cylinder and the connecting shaft are rotationally connected, and the movable cylinder and the lead screw are threadedly connected. The movable cylinder can be driven to rotate through the meshing transmission of the worm and the worm wheel, and the lead screw can be driven to move through the threaded transmission with the lead screw.

[0009] Preferably, the first limiting mechanism includes a connecting plate fixedly arranged at one end of the screw rod, and a limiting rod is fixed on the side of the connecting plate, and the limiting rod and the connecting shaft are slidably connected. When the screw rod moves, it can drive the connecting plate to move synchronously and lock the connected rod body.

The specific contents are as follows:

[0014] 1. When the rack body needs to be connected with the parts of the rod body, the rotating adjusting rod drives the movable cylinder to rotate through the meshing transmission between the worm and the worm wheel, and drives the screw rod to move through the threaded transmission between the movable cylinder and the screw rod. When the screw rod moves, it drives the limit rod to slide on the connecting shaft, so as to ensure the horizontal movement of the connecting plate. When the connecting plate approaches and contacts the rod body, the rod body can be locked by the fixing block to ensure the stability of the rack body after being connected to the rod body;

[0015] 2. After the rack body is connected through the connecting shaft passing through the inside of the bearing, the adjusting rod is then rotated in the other direction.
