[0027] An adjustment structure 7 is provided in the embedded hole 611; the adjustment structure 7 includes a rotating adjustment ring 71 and a matching seat 72; a matching hole 612 is provided in the middle of the bottom of the embedded hole 611; the bottom of the matching seat 72 is embedded in the matching hole 612, and the rotating device in the matching hole 612 is driven and connected to the bottom end of the matching seat 72; a groove 721 is provided in the middle of the top of the matching seat 72; the bottom end of the main shaft 751 is adapted to be movably installed in the groove 721; the bottom end of the main shaft 651 is semicircular 653; the middle part of the semicircular 653 is adapted to the movable setting of the groove 721; the rotating adjustment ring 71 is provided around the bottom end of the main shaft 651, and the rotating device in the embedded hole 611 is driven and connected to the rotating adjustment ring 71; the friction part 73 on the rotating adjustment ring 71 contacts the side wall of the main shaft 651; the friction part 73 covers the edge of the semicircular 653. A semicircular matching groove is set at the bottom of the main shaft.
