When the extension plate 506 is placed on the L-shaped support plate 507, the pressure plate 502 is pressed down by the air rod 501 to clamp the extension plate 506. During the clamping process, the position of the extension plate 506 can be corrected by the movement of the contact position between the triangular blocks 509 and the triangular slot 505.
