HS-TT-type inflatable jack works: the use of car exhaust filled balloon to maintain sufficient pressure to achieve the purpose of lifting the car. Use, will be equipped with check valve and balloon catheter connected, in the car idle state, the rubber tube connecting the cone tube inserted in the car exhaust pipe, automobile exhaust can be filled balloon, normally within 30 seconds airbag can give rise to the car requires a high degree; car was on hold after lifting for 45 minutes after use light spin-way valve, exhaust gas can be stable within 10 seconds, drain. The whole operation easy, simple and fast. 
 Features: use of the car's own exhaust, no additional equipment, 30 seconds, the car from the top, easy operation, simple, fast, high-tech military air bags with high strength composite materials, to adapt to high temperature and cold climate, unique check valve design, safety to ensure that the inflated balloon for 45 minutes after, secure self-locking connector to prevent the connecting pipe loose, easier operation, the unique design of reinforced insulation wear-resistant, durable, safe design of conical tube connection in the inflation pressure exceeds the design pressure fall off, to ensure the safe use, adaptive cone connection kit for various models, suitable for various road conditions, especially for sand, snow, trench rescue trapped cars, light body small, easy to carry.
