The invention discloses a rodless aircraft tractor with a traction mechanism. The vehicle comprises a vehicle frame, a walking driving system, a traction mechanism, a lifting system, an electric control system, a power supply system and an auxiliary device. The driving motor drives the chain to transmit during walking, and operation is reliable. During turning, the rotary motor drives the rolling pin turntable driving wheel, so that the rolling pin turntable drives the nose landing gear of the aircraft to rotate, and the turning radius is small. The lifting system 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. The traction mechanism adopts a slider-crank mechanism, an undercarriage traction connecting rod is connected with an aircraft nose undercarriage through a traction rod pin shaft during traction fixation, a hydraulic device and a wheel holding mechanism which are commonly used in an existing dev
