Among them, the bearing 14 is preferably a rolling bearing. The output end of the motor 6 is connected with the electromagnetic clutch 5, and specifically, the rotor of the motor 6 is connected with the electromagnetic clutch 5 through a flat key. The electromagnetic clutch 5 is connected with the transmission shaft 3, and specifically, the electromagnetic clutch 5 is also connected with the transmission shaft 3 through a flat key. The pinion 4 is fixedly mounted on the drive shaft 3 between two shoulders, in particular, the pinion 4 is mounted on the drive shaft 3 by a flat key.
