The upper guide plate is configured to limit the sliding direction of the slider. A lower guide plate is upwardly and vertically provided from the left edge and the right edge of the lower wing plate, respectively. The lower guide plate is configured to limit the sliding direction of the slider and arranged corresponding to the upper guide plate.
