The invention provides an airplane draw bar device. A main takeoff draw bar is arranged on an airplane main landing gear, and a front takeoff draw bar is arranged on an airplane nose landing gear. The airplane draw bar device adopts the structure that the front takeoff draw bar is arranged on the airplane nose landing gear, the front takeoff draw bar comprises a main pipe, a buffer is arranged at the front end of the main pipe, the other end of the buffer is connected with a traction ring through a shear bolt, a lifting mechanism consists of a hydraulic device arranged on the main pipe and an actuating cylinder of which one end is connected to the main pipe and the other end is connected to a support, and the hydraulic device drives a piston rod on the actuating cylinder to move so as to push the support to rotate by taking a support fixing point as the center. Through the adoption of the structure that the main takeoff draw bar and the front takeoff draw bar are arranged, the technical problems in the prior art that an airplane is inflexible in movement, a strong traction force has high probability of damaging the landing gears of the airplane and up-and-down adjustment of the draw bars is inconvenient are solved.
