The top edge of the lifting plate 201 is rotatably connected with an electric screw 215, and a screw sleeve 216 is sleeved on the electric screw 215. The bottom end of the screw sleeve 216 is fixedly connected with a sliding column 217, and the sliding column 217 is slidably connected with the sliding groove 208; the electric screw 215 causes the screw sleeve 216 to drive the connecting plate 214 to move, and at this time the sliding column 217 slides inside the sliding groove 208, so that the rotating frame 204 rotates, and at this time the rotating sleeve 205 slides along the clamping rod 203, and causes the clamping rod 203 to rotate toward the middle, and finally the rubber wheel 207 clamps the workpiece.
