With the movement of the active column 62 in the distribution control assembly 6, the intermediate conduit 64 sleeved in the active column 62 is synchronously driven to move, and the intermediate conduit 64 is connected to the side holes 53 on both sides. At this time, the air stored in the air storage assembly 3 The gas in the middle gas tank 31 is quickly released into the side hole 53 of the sleeve frame 51 through the exhaust pipe 32, and the gas is input into the intermediate conduit 64 through the side hole 53, and is input into the interior of the outer ring body 1 through the bottom tube 66, so that the outer ring body 1 is inflated and expanded to complete automatic inflation; when the gas is released after use, the gas injection valve 35 is opened, and the connecting rod 61 is pulled again at the same time, so that the outer ring body 1 discharges the internal gas through the distribution sleeve 5 and the gas storage assembly 3 to complete the exhaust; when the gas injection valve 35 is opened alone and connected to the external gas supply mechanism, the gas storage assembly 3 is re-injected with gas for storage and standby.
