When the position of the motor 12 needs to be adjusted, the first air pump 323 can be used to supply air to the input pipe 324. By inputting the air into the telescopic pipe 325, the telescopic pipe 325 can be extended, and the side of the telescopic pipe 325 drives the movable plate 322 away from the fixed plate 321 to adjust the tooth gap. The pneumatic force is used to achieve fast and accurate position adjustment, which not only enhances the flexibility of operation, but also ensures the consistency and repeatability of the tooth gap adjustment.
