The invention discloses a pneumatic retractable landing gear of an unmanned plane. The pneumatic retractable landing gear comprises an airplane wheel, a first connection rod, a second connection rod, a third connection rod, an air cylinder, a valve and a servo motor. The valve controls the air inflow amount of the air cylinder. The servo motor controls motion of the air cylinder. The second connection rod and the third connection rod are movably connected. The air cylinder is movably connected with the first connection rod. The air cylinder is movably connected with the second connection rod. The airplane wheel is movably connected with the first connection rod. The landing gear of the unmanned plane acts through the air cylinder, and through the simple connection rod structure, the folding and unfolding actions of the landing gear are completed when the unmanned plane takes off or lands. The overall weight and size of the landing gear are reduced, and the landing gear cost is lowered to some extent.
