The bevel gear 9 meshes with the bevel gear 6. Through the meshing relationship, when the bevel gear 6 rotates, it can drive the bevel gear 9 to rotate.

[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A guide mechanism 13 is provided on both the output shaft of the motor 5 and the auxiliary block 2. The guide mechanism 13 includes a rotating column 131. The rotating column 131 is fixedly sleeved on the outer side of the output shaft of the motor 5.
