The invention provides a high-speed unmanned aerial vehicle empennage deflection mechanism. An empennage deflection assembly comprises a fixing plate, a motor, a lead screw, a nut, a connecting rod, a crank, a rotating shaft and a fixing part. The number of the motors is at least one, the motors are fixed on the fixing plate, each motor is connected with one lead screw, each lead screw is provided with one nut, and the motors drive the lead screws to rotate and drive the nuts to move linearly; two ends of the connecting rod are respectively hinged with a nut and a crank; the two fixing parts are fixed to the fixing plate, the two ends of the rotating shaft extend into the fixing parts respectively to form shaft hole fit, and the crank is fixedly connected with the rotating shaft and the empennage. The empennage deflection assembly is arranged below the wings of the unmanned aerial vehicle. The device has the functions of force increasing and stroke amplifying, the rigidity of the deflection assembly is improved, and the requirements for high-bearing variable configuration and large rigidity of high-speed unmanned aerial vehicle folding empennage deflection can be met.
