The invention discloses a clamping-lifting device for an aircraft tractor. The device comprises a clamping mechanism and a lifting mechanism. The lifting mechanism adopts a lifting motor to drive a steel rope reel, and the nose landing gear of the aircraft can normally ascend and descend through a plurality of pulleys. During turning, the rotary motor drives the pin tooth rotary disc driving wheel, so that the pin tooth rotary disc drives the nose landing gear of the aircraft to rotate. The clamping mechanism adopts a slider-crank mechanism, an undercarriage clamping connecting rod is connected with an aircraft nose undercarriage through a clamping rod pin shaft during clamping and fixing, a hydraulic device and a wheel holding mechanism which are commonly used in an existing device are not adopted, the problems of maintenance of the hydraulic device, oil leakage and the like do not exist, and the device is clean, environment-friendly, low in production and maintenance cost, simple and novel in structure, hig
