The first gear 18 is a driving wheel and rotates with the drive of the motor 12. The sleeve Ⅰ13 on the motor support plate is coaxial with the sleeve Ⅲ20 on the liner 17. A second gear 21 is arranged between the sleeve Ⅰ13 and the sleeve Ⅲ20 on the liner 17. The step shaft on the second gear 21 passes through the sleeve Ⅰ13 and the sleeve Ⅲ20 respectively. The second gear 21 is a driven wheel. The second gear 21 meshes with the first gear 18 and rotates with the drive of the first gear 18.
