[0033] When the screw 110 is rotated to drive the L-shaped frame 107 to move downward, the L-shaped frame 107 drives the L-shaped rod 207 to move, and the L-shaped rod 207 drives the second piston 206 to move downward in the second cylinder 204, so that the air in the second cylinder 204 is discharged to the first cylinder 201 through the soft air guide pipe 205 and the hard air guide pipe 203, thereby extruding the first piston 209 and driving the connecting plate 210 and the clamping plate 208 to move, so that the clamping plate 208 clamps the workpiece to be processed. Then, the screw 110 is continuously rotated to drive the L-shaped frame 107 to move downward, and at this time, the clamping plate 208 has clamped the workpiece. When the air in the second cylinder 204 continues to be discharged to the first cylinder 201, the air will extrude the second conical plug 223, so that the second conical plug 223 no longer blocks the second conical groove 222, that is, the excess air is discharged from the second conical groove 222 and the air vent hole 225. When the grinding wheel 109 and the workpiece are in close contact, the rotation of the screw 110 is stopped, and at this time, the second conical plug 223 is driven to move under the elastic force of the second spring 226, so that the second conical plug 223 blocks the second conical groove 222, so that the clamping plate 208 is fixed at the position of clamping the workpiece.

[0035] When the workpiece is finished, the screw 110 is rotated reversely to drive the L-shaped frame 107 to move upward, and the L-shaped frame 107 drives the L-shaped rod 207 and the second piston 206 to move upward, so that the air in the first cylinder 201 is drawn into the second cylinder 204, and the first piston 209 moves into the first cylinder 201, and the connecting plate 210 and the clamping plate 208 are driven to move, so that the clamping plate 208 releases the workpiece.
