The sheet metal parts are clamped, and after adjustment, the pull plate is released to allow the spring to recover its deformation, so that the pressure plate can be moved downward to clamp and fix the sheet metal parts. "When it is used, the sheet metal parts to be welded are placed on the upper surface of the processing table, and the pull plate set on the upper surface of the mobile frame is pulled, which will cause the pressure plate to move upward and cause the spring to be squeezed and deformed.
