Preferably, the dynamic shearing blade group comprises a dynamic shearing blade A, a dynamic shearing blade B and a dynamic shearing blade C which are sequentially arranged from back to front, the section of the dynamic shearing blade C is L-shaped, and the left dynamic shearing blade C and the right dynamic shearing blade C are arranged in a buckling mode.
Preferably, the shear body is formed by buckling and welding two channel steels.
Further preferably, the bottom edge of the dynamic shear blade C abuts against the bottom surface of the dynamic shear knife handle.
Further preferably, the maximum opening and closing angle of the movable shearing knife handle is 65-70 degrees.
The utility model has the advantages that:
the cutting edge of the bottom surface of the movable shearing blade group is in a double-fold line shape, in the shearing process, the movable shearing blade group provides backward component force for the waste steel, the waste steel is limited between the movable shearing blade group and the fixed shearing blade group, and the waste steel is effectively prevented from falling out from the position between the movable shearing blade group and the fixed shearing blade group.
