The ascending or descending member is connected to the ascending or descending groove in order to vertically ascend or descend to a certain distance. The rubber cutoff plate is connected to the lower part of the ascending or descending member. The pressure push bar installed in an installation hole of the pressure push bar is vertically movable to a certain distance.
