Through the setting of the clamping mechanism, after the metal plate is cut once, the hydraulic telescopic cylinder is started to drive the water storage box to rise, drive the connecting rod to rise, drive the sliding column to rise along the sliding groove, and the rising sliding column drives the bending plates to approach each other, drives the baffles to approach each other, and starts the rotating motor to rotate the threaded rod, so that the push plate pushes the plate to move. The two baffles limit the movement of the plate to avoid the plate from shifting during the automatic feeding process, thereby facilitating the continuous cutting of the metal plate.
