[0038] In another embodiment, Figure 1-Figure 6 As shown, one side of the limiting block A4 is slidably installed inside the limiting groove B27.

[0039] The limiting groove B27 limits the descending and ascending trajectory of the cutter 24 through the limiting block A4, thereby increasing the stability of the device during shearing.

[0040] In another embodiment, Figure 1-Figure 6 As shown, one end of the fixing block 20 passes through the interior of the groove 8 and extends to the outside of the mounting seat 17 , one end of the tension spring 21 is fixedly mounted on one side of the movable rod 15 , and the output end of the adjusting telescopic rod 31 is closely attached to one side of the movable rod 15 .

[0041] When the movable rod 15 drives the steel to push forward, the elastic force of the tension spring 21 can pull the movable rod 15 back for the next forward push, and adjusting the length of the telescopic rod 31 can control the distance that the movable rod 15 pushes the steel plate. There is no need for manual feeding and the punching positions are more uniform, which improves the working efficiency of the device.
