The gear 23 is engaged with the rack 25, so that the rotation of the gear 23 can drive the rack 25 to move. A slider 21 is provided at the bottom of the rack 25. Relying on the slider 21, the rack 25 can slide along the slide groove 22. The rack 25 is fixed to the moving mechanism through the connecting rod 20.
