Since the bevel gear 515 and the bevel gear 513 are meshed and connected, the rotation of the bevel gear 513 can also drive the worm 516 to rotate. At the same time, the worm 516 drives the worm wheel 517 to rotate in the original position. When the worm wheel 517 rotates, it can drive the threaded rod 518 to rotate in the limit plate 5101. At this time, the front and rear moving seats 5104 can move to the opposite side on the surface of the threaded rod 518. , because the moving seat 5104, the second hinged plate 5103 and the bending plate 5102 are hinged on the workbench 1, when the moving seat 5104 moves, the bending plate 5102 can move to the side of the placement table 524, and at the same time, the bending plate 5102 drives the second T-block 5105 to slide in the third T-slot 519. When the bending plate 5102 moves, the pressing plate 7, the first pressing roller 8 and the second pressing roller 9 cooperate to facilitate the bending operation on the left and right ends of the steel plate 6;

[0055] When the handle 522 is turned, the rotating shaft 523 is driven to rotate, and the rotating shaft 523 drives the placement table 524 to rotate. The placement table 524 can also drive the annular slide plate 525 to slide in the annular slide groove 521, so that the steel plate 6 placed on the placement table 524 can be driven to rotate, which is convenient for the later bending operation of the front and rear ends of the steel plate 6.
