The invention belongs to the technical field of aircrafts, and particularly relates to an adjustable speed reducer. The device comprises a grating sleeve, a sliding rail and a grating sleeve joint, wherein the grating sleeve is provided with a sliding rail track and a grating sleeve joint; one end of the grating sleeve actuator is connected with the aircraft, and the other end of the grating sleeve actuator is connected with the grating sleeve joint; the clamping plate is provided with a sliding rail rod and a clamping plate connector, the clamping plate is embedded in the grating sleeve, and the sliding rail rod of the clamping plate is installed in the sliding rail track of the grating sleeve in a sliding mode; one end of the clamping plate actuator is connected with the aircraft, and the other end of the clamping plate actuator is connected with the clamping plate connector. Adjustment of the speed reduction effect can be achieved through movement of the clamping plates, the speed reduction device is easy to open under the high-altitude large Mach number and not prone to deformation after being opened, the folding and unfolding problem of the speed reduction device under the high-altitude high-speed condition can be solved, and through the design of the grating sleeve and the clamping plates, change of the resistance increasing amount can be achieved, the structural weight can be saved, and the design difficulty can be reduced.
