Air spring slow-releasing mechanism

The invention discloses an air reed type slow release mechanism which can improve the reliability of launching a rocket. The air reed type slow release mechanism comprises a gas supply system (1), a slow release cylinder (2), a traction cylinder (3), a soleplate (4), a traction arm (5), a swinging lever (6) and a lever arm (7); the soleplate (4) is connected with a rocket launching pad; the leverarm (7) is fixed on the soleplate (4); the lower ends of the slow release cylinder (2) and the traction cylinder (3) are movably fixed on the soleplate (4) respectively; the upper end of the slow release cylinder (2) is movably connected with the lever arm (7); the upper end of the traction cylinder (3) is connected with the lower end of the traction arm (5); the upper end of the traction arm (5)is fixedly connected with the swinging lever (6); the other end of the swinging lever (6) is movably connected with the lever arm (7); and the gas supply system (1) provides high-pressure gas for theslow release cylinder (2) a
