When the second power transmission member 7 is connected with the first power transmission member 6, the transmission protrusion 61 is inserted in the groove 72. The transmission protrusion 61 and the groove 72 cooperate with each other, so that when the second pulley 42 rotates, the driving bevel gear 511 follows the rotation to transmit power to the meshing transmission mechanism 5.

[0049] Specifically, as shown in Figure 2 or Figure 4 , the belt transmission assembly 4 includes a first pulley 41, a second pulley 42 and a transmission belt 43, the first pulley 41 is fixed on the output shaft of the motor 3, the second pulley 42 is sleeved on the outer wall of the knocking shaft 2, the first power transmission member 6 is connected to the side wall of the second pulley 42, the first power transmission member 6 and the second pulley 42 are integrally formed, and the transmission belt 43 is wound on the outer wall of the first pulley 41 and the second pulley 42.
