Alternatively, two limiting protrusions may be provided at the end of the transmission shaft 110, and the disc body 114 may be disposed between the two limiting protrusions. Of course, the limiting structure mentioned here may be in other forms as long as the function of limiting the axial position of the disc 114 and the transmission shaft 110 can be achieved.

In the embodiment of the present invention, the first through hole 122 is a rotation hole, and the cross-sectional shape of both ends of the transmission shaft 110 is adapted to the shape of the first through hole 122. The first through hole 122 is a rotation stop hole, and the drive shaft 110 is inserted into the first through hole 122 to prevent the disc 114 and the drive shaft 110 from rotating relatively.
