Thereby, the motor is doubly fixed under the pressing of the pressing plate 9 and the clamping of the clamping plate 8. In the process that the two fixing plates 12 are mutually close, the tip of the fixing plate 12 slides on the unidirectional teeth on the abutting plate 5, the abutting plate 5 continuously extrudes the second pressure spring 6 under the action of the abutting plate 12, and the abutting plate 5 continuously reciprocates up and down, so that the fixing plate 12 can be ensured to normally move.
