The invention belongs to the technical field of aerospace, and particularly relates to a jacking type undercarriage buffer structure which comprises an outer cylinder, a floating piston, a piston rod and an external connector. The piston rod is provided with an inner cavity and sleeved with the outer cylinder, and the floating piston is sleeved with the inner cavity of the piston rod. The floating piston, the side wall of the piston rod and the outer cylinder form a buffer cavity, and hydraulic oil and compressed air are injected into the buffer cavity according to a preset proportion. The floating piston and the piston rod form a jacking cavity, the jacking cavity is provided with an external connector, hydraulic oil is injected into or discharged out of the jacking cavity through the external connector so that the piston rod can stretch out of or retract into the outer cylinder, the external connector is used for being externally connected with an external hydraulic source, and the hydraulic oil injected into the external hydraulic source can make the buffer jack an airplane.
