Plate shearing machine with protection function

The plate shearing machine with the protection function comprises a bottom plate, a base is fixedly connected to the top of the bottom plate, a collecting box is arranged on one side of the base, a machining cabinet is fixedly connected to the top of the base, a notch is formed in the front side of the machining cabinet, and L-shaped supporting plates are fixedly connected to the two sides of the machining cabinet. One side of the L-shaped supporting plate is fixedly connected with a first electric telescopic rod, and the tail end of the first electric telescopic rod is fixedly connected with a protective sealing plate. When a workpiece is subjected to plate shearing operation, a first electric telescopic rod can drive a protection sealing plate to conduct sealing protection treatment on a notch, the situation that the workpiece splashes in the plate shearing process, and potential safety hazards are caused to workers is avoided, and a second electric telescopic rod can drive a push plate to move in a cleanin
