The invention relates to an actuator cylinder for cabin door unfolding and a pneumatic drive unfolding device. The actuating cylinder comprises an outer cylinder, an end cover and an outer cylinder threaded end cover are arranged at the two ends of the outer cylinder respectively, an inner cylinder is arranged in the outer cylinder, a piston rod is arranged in the inner cylinder, the inner cylinder is slidably connected with the piston rod through a head assembly, and the other end of the inner cylinder is connected with a piston lug. An air injection hole is formed in the end cover, a first air cavity is formed between the end cover and the inner cylinder head assembly, one end of the piston rod is connected with an inner cylinder threaded end cover, and the interior of the inner cylinder is divided into a first oil cavity and a second oil cavity through a piston head at the other end of the piston rod. A second air cavity is formed among the outer cylinder threaded end cover, the outer cylinder and the inner cylinder, and a floating piston is arranged between a piston head of the piston rod and a piston lug. According to the invention, the cabin door, the undercarriage and the like can be effectively driven.
