The adjustment limit structure 1 and the supporting bearing structure 2 are first docked and installed, and the upper end limit guide block 16 of the supporting bearing structure 2 is adapted to be docked with the second protective contact seat 6 to fix them. A magnetic suction structure is adopted to facilitate rapid positioning. Then, the ring seat 15 is put on the head position, and a plurality of fastening screws are screwed. The frame 14 is squeezed and limited by tightening the rotating frame 14, so as to help the support bearing structure 2 to limit the support. After the support bearing structure 2 is limited, the upper adjustment limit structure 1 can also be limited. Then the user adjusts the limiter component 7 on the first limit frame 3 and the second limit frame 5 to reach the appropriate position, and screws the additional screws on the side end longitudinal groove to achieve the positioning process. Then the user adjusts the regulating limit seat 11 and the guide tube 12 so that the regulating limit seat 11 and the guide tube 12 slide on the groove rail 13 to reach the appropriate position, and screws the screw nut 10 to perform the limiting process of the regulating limit seat 11.
