At this time, the operator starts the movement of the track strip 200a. The movement of the track strip 200a will drive the rotation of the third gear 304 through the external support member, thereby driving the rack 303 on the side wall of the telescopic slide rod 301 to move, and the movement of the telescopic slide rod 301 will pull the steering rod 106 forward and backward for adjustment in the longitudinal direction.
