When the control screw is rotated to drive the first slider 2 to move in the X direction in the first chute, the second slider 4 engaged with the first slider 2 moves along the first engaging surface 21 and the second engaging surface 22. Since the first engagement surface 21 and the second engagement surface 22 are inclined surfaces and the second slider 4 is restricted to move only in the Y direction, the first slider 2 drives the second slider 4 to move in the Y direction. When the second slider 4 moves along the Y direction, the limiting block 7 fixedly connected with the second slider 4 is driven to move along the Y direction together, so that the size of the workpiece in the Y direction is limited and adjusted.
