The invention provides a release device for an aircraft cockpit control system. The release device comprises a ball nut base assembly, a lead screw assembly, a bearing sleeve assembly, a cam sliding block, a stop piece and a spring. One end of a lead screw in the lead screw assembly is connected with the ball nut base assembly, and the cam sliding block and the bearing sleeve assembly are sequentially installed at the other end of the lead screw in a nested mode. The two studs are symmetrically connected to the two sides of the lead screw in a threaded mode, and one idler wheel is installed at the end of each stud. Spring mounting holes are formed in the matched end faces of the cam sliding block and the sleeve, a radial groove is formed in the end face of one side of the spring mounting holes, the roller is contained in the radial groove in a semi-embedded mode, and the spring is compressed through the cam sliding block to provide limiting force; the fixed end of the stop piece is axially fixed outside the sleeve through a screw, a boss is arranged on the inner wall face of the free end of the stop piece, and a groove hole matched with the boss is formed in the axial corresponding position of the cam sliding block. The disengaging device is used for linkage or disengaging of two sets of cockpit control systems.
