Swing type residue pressing shear

The invention discloses a pair of swingable excess pressure shears, which comprises a shear shank, a pair of shear blades, a pair of swing rods and a pair of pressure shears, wherein one side of the shear shank is provided with a shearing surface; the scissor head is provided with a cutting edge, the scissor head is rotatably installed on the side, away from the shearing face, of the scissor head through a rotating shaft, and the center of the rotating shaft and the center of the scissor head are eccentrically arranged so that the scissor head can rotate away from the shearing face under the action of the gravity of the scissor head; the guiding mechanism is used for guiding the scissor head to rotate close to or away from the shearing face, and the blades are used for being located on the shearing face after the scissor head rotates close to the shearing face. According to the swinging type residual pressing shear, when the shearing action is carried out, the guide mechanism can drive the cutting edge of the
