[0025] In this method, a column seat 17 is fixedly connected to the top of the nut fitting groove 18, and the column seat 17 is fitted and inserted into the inner side of the mounting groove seat 15. A limiting screw 16 is screwed and installed on the side wall of the mounting groove seat 15, and a limiting hole 19 is opened on the side wall of the column seat 17, which is adapted to the cross-sectional size of the limiting screw 16.
