[0038] Further as Figure 1-3 As shown, it is worth explaining in detail that in order to be able to clean up the debris generated during the top processing of the workpiece to be processed under the linkage action of the above-mentioned synchronous positioning structure 5, a cleaning structure 7 is provided, including two symmetrically arranged U-shaped rods 71, the two ends of the two U-shaped rods 71 ​​are respectively fixed to the outer side of the vertical plate 2, and the sliding grooves provided on the two U-shaped rods 71 ​​are slidably connected with sliders 72 with a vertical cross-section of an I-shaped structure, and a cleaning brush 73 is fixed between the opposite ends of the two sliders 72, one of the sliders 72 is threadedly connected with a screw b74, and both ends of the screw b74 are rotatably connected to the sliding groove, one end of the screw b74 extends to the outer side of the U-shaped rod 71 and is fixed with a gear 75, and a toothed plate 76 is meshingly connected to the lower part of the gear 75, and the toothed plate 76 is fixed to the outer side of the transmission plate 53.

In addition, , the drilling and tapping cutter 42 can continue to move downward to realize the processing action. In addition, the tooth plate 76 will move with the transmission plate 53 and transmit the gear 75, so that the screw b74 rotates, so that the cleaning brush 73 can move from left to right. After the drilling and tapping cutter 42 is processed and the lifting plate 4 is raised, the gear 75 drives the screw b74 to reverse, so that the cleaning brush 73 moves from right to left. After the drilling and tapping is completed, the top debris of the workpiece can be actively cleaned without manual hand-held wiping tools for cleaning, which further improves the processing efficiency.
