[0032] When this embodiment works: After welding is completed, the push rod 15 no longer pushes the second inclined plane block 14. At this time, the lifting plate 13 starts to move downward and reset under the action of the movable end of the second elastic telescopic rod 12. The movement of the lifting plate 13 drives the connecting rod 163 to start moving. The movement of the connecting rod 163 pushes the scraping rod 162 to move along the direction of the slide rail 161, which can effectively remove residues such as welding slag, metal debris, and oil stains on the surface of the workbench 6, keep the workbench 6 clean, prevent the residues from contaminating the copper bars processed subsequently, ensure the welding and processing quality.

[0033] When starting welding, the lifting plate 13 moves upward, driving the scraping rod 162 to start moving toward the lifting plate 13 and no longer pushing the fixing rod 165.
