[0027] When the central shaft 35 rotates, it drives the central gear 31 to rotate. The rotation of the central gear 31 synchronously drives the first gear 32, the second gear 37, and the third gear 39 to rotate in opposite directions. The central shaft 35 drives the central spindle assembly 1 to rotate. The first gear 32 drives the first rotating shaft 34 to rotate. The second gear 37 drives the second rotating shaft 36 to rotate.

Then, the central screw 13 on the inner sleeve 11 is inserted into the threaded hole 16. The inner sleeve 11 is rotated, which drives the central screw 13 to rotate and move. The central screw 13 drives the frustum 17 to rotate and move. When the frustum 17 is in contact with the wedge block 171, the movement of the frustum 17 drives the wedge block 171 to move. The movement of the wedge block 171 drives the locking pin 174 to move. The locking pin 174 is inserted into the locking groove 173, thereby fixing the positioning blocks 14. The installation of the central spindle assembly 1, the first auxiliary spindle assembly 2, the second auxiliary spindle assembly 5, and the third auxiliary spindle assembly 6 is completed.
