When it is necessary to shear the steel, the steel is placed on the placement plate 102, and at this time, the push rod 105 is started to drive the shearing knife 104 to move downward, so that the steel is sheared under the extrusion of the shearing knife 104 and the placement plate 102. After the shearing is completed, the sheared steel automatically falls into the storage box 101, and then the push rod 105 contracts to lift the shearing knife 104 to complete the shearing process, and also includes:
