Due to design and manufacturing reasons, the distance from the first body 10 to the center of the centering shaft 22 may be set differently. In order to meet the needs of adjustment, the centering shaft 22 may have a tapered surface. During use, the position of the centering shaft 22 is adjusted so that different positions of the tapered surface contact the first body 10 to adjust the distance between the first body 10 and the center of gravity of the centering shaft 22 .

Correspondingly, the limiting shaft 23 can also be set to abut against the tapered surface of the first body 10 to realize angle adjustment.

In order to prevent the first body 10 from moving away from the positioning plane 21 when contacting the cone surface, the small end of the cone surface can be made to face the positioning plane 21 .

At the same time, in order to enable the first body 10 to rotate around the centering shaft 22 to the limit shaft 23, the first body 10 can be provided with a V-shaped groove correspondingly, and the two side walls of the V-shaped groove contact the outer surface of the centering shaft 22 .
