A folding arm type shear rack of an airport lifting loading and unloading platform comprises a rotation bracket and a shear rack body arranged on the rotation bracket. A lifting oil cylinder is arranged between an inner shear rack body and the rotation bracket. One end of the lifting oil cylinder is hinged to the upper middle portion of the inner shear rack body. The other end of the lifting oil cylinder is hinged to the rotation bracket. An outer shear rack body is composed of an outer shear arm and a folding arm shear rack body hinged to the upper end of the outer shear arm. A folding arm oil cylinder is arranged between the folding arm shear rack body and the outer shear arm. One end of the folding arm oil cylinder is hinged to the folding arm shear rack body, and the other end of the folding arm oil cylinder is hinged to the upper end of the outer shear arm. By means of the hinged type outer shear arm, one end of the shear arm can rotate, and the longitudinal inclination adjustment range of the platform can meet the function requirement.
