[0028] One end of the outer side of the workbench 1 is fixedly connected to a connecting frame 5, and the outer end of the connecting frame 5 is fixedly connected to a motor 2 6. The output end of the motor 2 6 passes through the connecting frame 5 and is provided with a screw 8 inwardly. A threaded block 9 is threadedly connected to the screw 8.
