[0047] The advantages of the eccentric setting of the present application are illustrated below by way of example: Figure 3-4 The center O1 of the spindle mounting hole 21 of the present application (equivalent to the center O1 of the spindle 3) is eccentrically arranged with respect to one end of the hinge plate 2 and the rotation center O of the base 1, and the eccentricity is O1O. The rotation angle of the eccentricity O1O is A. The reference point a on the spindle 3 rotates at an angle relative to the center O1 of the spindle 3, and the center O1 of the spindle 3 moves in position relative to the rotation center O. The rotation is also at an angle A. Compared with the conventional concentric scheme, the position variation range of the reference point a on the spindle 3 is larger.

[0048] Further, such as Figure 1 One end of the hinge plate 2 is rotatably connected to the base 1 via a rotating shaft, and the center of the main shaft mounting hole 21 is eccentrically arranged with respect to the center of the rotating shaft.
