Based on the structural principle of drive chain for pneumatic disc valve and the calculation of switching torque，This paper purposes to optimize the manufacturing cost，improve the structural strength and stiffness，and reduce the motion impact．Taking the cylinder travel，cylinder output force，and the length of fixed frame as the research objects，the initial direction of cylinder output force and cylinder stroke，cylinder output force are analyzed by geometric modeling and numerical calculation．Meanwhile，the influence of the angle design for piston rod and rocker shaft on the length of disc valve fixing frame is discussed，which improve the structural strength，stiffness，and reduce the influence of impact load on the fixing frame.
