The invention discloses an improved ultrathin shear type hoister shearing arm. The improved ultrathin shear type hoister shearing arm comprises a base, a hydraulic device, an inner shearing arm, an outer shearing arm, a hoisting platform and an approach bridge. Two sliding grooves are formed in the upper half part of the inner shearing arm and the upper half part of the outer shearing arm respectively, two movable supporting rods are arranged in the center of the lower half part of the inner shearing arm and the center of the lower half part of the outer shearing arm respectively, and the other ends of the supporting rods are inserted into the sliding grooves. The improved ultrathin shear type hoister shearing arm is simple in structure, convenient to use and good in stability, and improves the safety of a hoister in the use process.
