When the docking device rotates the workpiece, the workpiece is driven to rotate by the pulley. By rotating the workpiece for welding, the uniformity and consistency of the weld can be ensured, and welding defects can be reduced. When the knob is not rotated, the limit is achieved by inserting the card block into the limit groove to prevent external force from touching and causing the adjusting rod to rotate, which may cause clamping operation errors.

After the clamping device has clamped the workpiece, the workpiece can be welded by the welding device.
