A new-style pneumatic jack consists of five parts, namely, an air bag, a draw bar, a base plate, a pulley and an air duct. The air bag part of the new-style pneumatic jack is divided into an upper bag, a middle bag and a lower bag in sequence from top to bottom, and the inner spaces of three air bag bulges are mutually independent. The side of each air bag is equipped with an air valve, and adjacent two air bag bulges are connected in series by a pneumatic stop valve used for the air duct. An upper air bag bulge is equipped with an anti-skidding rubber plate, so as to come into contact with the chassis of a car, and a lower air bag bulge is connected with the base plate. The air bag is equipped with a pneumatic valve device, and the device inflates quickly when the air bag enters the working state, and can be unloaded slowly during deflation. The new-style pneumatic jack is additionally equipped with a safety protection device on the basis of enhancing air bag strength, and overcomes the defect that the safety factor of a pneumatic jack in the prior art is low.
