The invention discloses a resettable inflation unlocking device. The air cylinder comprises a cylinder body with a cavity structure, the head end of the cylinder body is communicated with an air inflation hole, the tail end of the cylinder body is communicated with a cylinder sleeve which is coaxial with the cylinder body, a cylinder sleeve hole is formed in the bottom end face, away from the cylinder body, of the cylinder sleeve, and an air pressure rod is arranged in a cavity formed by the cylinder body and the cylinder sleeve in the axial direction. The periphery, close to the cylinder sleeve end, of the air pressure rod is sleeved with a locking rod. The cylinder body comprises a first annular step, a second annular step and a third annular step. The air pressure rod comprises an air pressure rod head, a first annular boss, a first annular groove, a second annular boss and an air pressure rod tail. The locking rod comprises a locking rod head and a locking rod tail, the outer wall of the locking rod head is matched with the inner cavity of the cylinder body, part of the locking rod tail is located in the cavity of the cylinder body, and part of the locking rod tail extends out of the cylinder sleeve hole. The device is of a pure mechanical structure design, and the unlocking function and the repeated use function are achieved through mutual cooperation between the air pressure rod and the locking rod.
