DETAILED DESCRIPTION

[0016] In order to more clearly illustrate the technical solution of the utility model, the utility model is further described below in conjunction with the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the utility model. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on this drawing and embodiment, which all belong to the protection scope of the utility model.

The output end of the cylinder 8 enters the interior of the protective cover 3 and a spring 9 is sleeved on the cylinder 8. The two ends of the spring 9 are respectively fixedly connected to the protective cover 3 and the cylinder 8. A fixed plate 10 is arranged between the output ends of the cylinder 8, and the fixed plate 10 is fixedly connected to the blade 4. When shearing, the protective cover 3 first contacts the plate, and then compresses the spring 9 to make the blade 4 contact the plate. The waste generated by shearing is blocked by the protective cover 3 to avoid harm to the staff. The left and right sides of the protective cover 3 are provided with observation windows 16 for the staff to observe the processing situation. A feeding device is arranged on the workbench 1.

The observation window 16 is convenient for the staff to observe the processing situation. Elastic telescopic rods 5 are arranged on the front and rear sides of the protective cover 3 to press and fix the plate to prevent the plate from displacement and ensure the processing accuracy. The elastic telescopic rods 5 shrink to different degrees due to the thickness of the plate, and there is no gap between the plates, which has a good protective effect on plates of different thicknesses. The ball 7 rolls in contact with the plate to avoid wear on the surface of the plate. At the same time, the uncompressed elastic telescopic rods 5 on both sides of the plate limit the plates of different widths to avoid lateral movement of the plates. It is highly practical. When processing irregular plates, the positions of the two pushing blocks 14 are adjusted respectively to match the edge contour of the plate, which is convenient for feeding and cutting, with a wide range of adaptability and strong flexibility.
