[0028] Reference Figure 1 , Figure 2 A motor 3 is fixedly installed on the internal end surface of the chassis 1, and one end of the rotating shaft of the motor 3 and one end of the first transmission shaft 4 are fixedly connected with a bevel gear 5, and the two bevel gears 5 are meshingly connected.
