It should be noted that the vent assemblies 3 and the adhesive assemblies 4 are arranged at intervals, i.e. one adhesive assembly 4 is arranged at a distance from one vent assembly 3. When the buffer air bag is used repeatedly, the buffer air bag can be exhausted only by pulling the tail end exhaust component 3; after the air bag is exhausted, the bonding assemblies 4 adjacently arranged through the tail end exhaust assemblies 3 can be bonded in a heat sealing mode, after bonding, the air bag can be inflated through connecting the inflation air tap with the opening of the air inlet channel 5, and the air bag can be inflated through the air inlet channel 5, so that the air bag body can be inflated continuously through the air inlet. Then the tail end exhaust component 3 is pulled, so that the buffer air bag can be exhausted again; after the buffer air bag is exhausted again, the bonding assembly 4 adjacently arranged at the tail end of the exhaust assembly 3 can be subjected to heat sealing bonding again, and after bonding, the air bag can be inflated again through the opening of the air inlet channel 5 connected with the air inflation nozzle, and the air bag body can be inflated through the air inlet channel 5 continuously through the air inlet. It should be noted that the number of the exhaust assembly 3 and the bonding assembly 4 may be arranged according to actual use requirements, and the number of the bonding assemblies 4 arranged is the number of times of repeated use. In particular, the reuse of the airbag may be considered to be possible by discarding the broken portion cut after recovery, and the reuse may be realized by resealing.

When the exhaust assemblies 3 are multiple, a bonding assembly 4 is arranged between every two adjacent exhaust assemblies 3, and one side, closest to the air inlet, of all the exhaust assemblies 3 is also provided with the bonding assembly 4.
Illustratively, when the exhaust assembly 3 is one, the bonding assembly 4 is disposed on the side of the exhaust assembly 3 adjacent the air intake. When the air bag is required to be exhausted after being used, the air bag can be exhausted only by pulling the tail end exhaust component 3; after the air bag is exhausted, the bonding assemblies 4 adjacently arranged through the tail end exhaust assemblies 3 can be bonded in a heat sealing mode, the bonding assemblies 4 are arranged on one side, close to the air inlet, of the exhaust assemblies 3, after bonding, the air bag can be inflated through the opening, connected with the air inlet channel 5, of the air inflation nozzle, and therefore the air bag body can be inflated through the air inlet continuously.
