[0025] The support ring 3 is subjected to the pressure of the clamping plate on the movable clamp 403 and stays in the accommodating groove. The clamping plate applies pressure upward to fix it. At the same time, the spring 404 applies pressure to one side of the movable clamp 403, causing the side facing upward to deviate toward the side of the support ring 3 to fix it.
[0026] See also Figure 6 , 7 The clamping connection mechanism 4 includes a fixed telescopic rod 701 connected to the bottom of the connecting seat 6, and the telescopic end of the fixed telescopic rod 701 is connected to a fixed sleeve 702 that fixes the movable splint 403 to prevent it from moving, and the fixed sleeve 702 matches one end of the movable splint 403.

Through the action of the spring 404, the movable splint 403 is reset and fixed, and the fixed connection is performed. Then, the fixed telescopic rod 701 at the bottom of the connecting seat 6 is extended to drive the fixed sleeve 702 to move and fix the movable splint 403. Then, the auxiliary fixing clamp 502 of the auxiliary connecting mechanism 5 is clamped to clamp and connect the supporting rod 301 so that the rotation direction is fixed. Then, the supporting motor 801 is rotated to drive the threaded sleeve 802 to rotate, and then the threaded rod 803 is driven to rotate. Through the meshing of the threaded rod 803 and the threaded sleeve 802, it is extended upward to be connected with the supporting seat 2 to form axial fixation.
