When the sheet metal is cut, the first electric push rod 402 can drive the connecting block 401 to move when it is started, and when the connecting block 401 moves, it can also drive the rotating rod 49 to move in the inclined slide groove 48. At this time, the rotating rod 49 can also rotate on one side of the connecting block 401 when it moves. When the rotating rod 49 moves to the oblique lower position of the inclined slide groove 48, the connecting seat 46 can drive the connecting plate 45 to move, and the connecting plate 45 drives the return-shaped plug plate 43 to move out of the return-shaped slot 41. At the same time, the first T-plate 44 slides in the first T-slot 42, which can make the return-shaped plug plate 43 and the return-shaped base 403 present a new height, which can further prevent the debris generated when the sheet metal is cut from falling on the workbench 3; The workbench 3 is sprayed with water by a hand-held water pipe assisted by humans, so that the sheet metal debris and water on the workbench 3 flow into the circular water tank 11 together, and are transported to the collection box 6192 through the outlet tank 12. The water and the sheet metal debris are separated and screened with the cooperation of the filter plate 6193. When the sheet metal needs to be collected separately, when the second electric push rod 71 is started, the second electric push rod 71 can drive the fixed plate 73 to move, and the fixed plate 73 drives the third hinged rod 75 at both ends to be hinged. When the third hinged rod 75 and the push plate 77 are hinged, the push plate 77 can also The annular slider 76 is driven to slide in the arc groove 74. On the other hand, the push plate 77 can also drive the mounting block 702 to move when it moves. When the mounting block 702 drives the T-block 78 to slide in the third T-slot 701, the mounting plate 79 can also be driven to move. When the mounting plate 79 moves, it can drive the partition plate 703 to move from the long slot 705 until the two partition plates 703 are in contact, so that the bottom space of the filter plate 6193 is sealed. With the cooperation of the circular rubber sealing plate 704, the water in the collection box 6192 will not overflow from the long slot 705. When the first motor 612 is started, the first motor 612 can drive the first long rod 6106 to rotate, and when the first long rod 6106 rotates, the first half gear 6107 can be driven to rotate. Since the first half gear 6107 and the second half gear 6108 are meshed and connected, the first half gear 6107 and the second half gear 6108 rotate in opposite directions, and when the second half gear 6108 rotates, the second long rod 6109 can be driven to rotate in the long board 611. When the two fixing blocks 613 are driven to rotate, since a second hinged rod 6105 is hinged between the two fixing blocks 613 and the two slide plates 614, when the fixing blocks 613 rotate, the second hinged rod 6105 can be hinged to drive the slide plates 614 to slide in the slide groove 6104, and the slide plates 614 are hinged to the first hinged rod 615. At this time, the first hinged rod 615 can also drive the rotating rod 616 to rotate in the fixing seat 6102, and the gear row 6101 can also move. When the tooth row 6101 moves, it can drive the second T-shaped plate 6171 to slide in the second T-shaped groove 617. At the same time, the tooth row 6101 and the gear 618 are meshed and connected. At this time, the gear 618 can be driven to rotate, and the gear 618 drives the rotating shaft 619, and the rotating shaft 619 drives the rotating plate 6191 to rotate. The rotating plate 6191 drives the collecting box 6192 to rotate, and the two collecting boxes 6192 can be rotated to the opposite side at the top of the collecting box 1. During the rotation process, affected by gravity, The sliding plate 626 can slide directly in the arc groove 621. When the second motor 625 is started, the second motor 625 drives the long rotating rod 623 to slide in the sliding plate 626. At this time, the long rotating rod 623 can also drive the bristles 624 to rotate, so that when the collection box 6192 rotates and flips, the bristles 624 can sweep from the upper end to the lower end from the upper position of the filter plate 6193, and can drive the sheet metal debris in the gap of the filter plate 6193 to be swept out, so that the sheet metal debris can be directly collected in the collection box 1.
