The device only simply fixes the workpiece horizontally to avoid contact with the punching plate At the edge of the workpiece, the lowering of the stamping plate drives the workpiece down during stamping, and forces the workpiece to shrink toward the punching groove. This shrinkage does not affect the accuracy of the workpiece. This device only prevents the workpiece from moving over a large distance during the stamping process. The setting of the spring is convenient to better limit the bottom plate and the anti-slip block, the setting of the elastic rope is convenient to better drive the bottom plate and the anti-slip block to reset, and the setting of the limit rod is convenient to better limit the bottom plate and the anti-slip block;
