[0012] 1. After taking the bottle out of the elastic bag of the hanging board, the bottle can be carried alone; after the bottle is embedded in the elastic bag, the elastic bag can lock it, and then the hanging board can be hung on the belt or other places on the human body that can be hung by using the elastic buckle; at the same time, the elastic strap on the hanging board can be used for the arm to pass through, so that the hanging board and the bottle can be constrained on the arm; finally, the bottle can adapt to different wearing methods;

[0013] 2. The high-pressure gas pipe is threadedly connected to the internal thread groove of the bottle body by using the threaded connection end. At this time, the detachable connection between the high-pressure gas pipe and the bottle body can be realized, which is convenient for disassembly, assembly and replacement of the high-pressure gas pipe;

[0014] 3. Using the hexagonal rotating head integrally arranged at one end of the threaded connection end close to the high-pressure gas pipe, the hexagonal rotating head can conveniently rotate the threaded connection end;

[0015] 4. When the threaded connection end is threadedly connected in the internal thread groove, the hexagonal rotating head can be pressed against the pressing plane, thereby increasing the pressing area of ​​the hexagonal rotating head through the pressing plane, which is conducive to the stable locking of the hexagonal rotating head; at the same time, the hexagonal rotating head can press the rubber sealing ring against the annular groove, thereby sealing the thread gap through the rubber sealing ring;

[0016] 5. The high-pressure air pipe is used as a spiral elastic pipe, so that the high-pressure air pipe can be easily extended and moved, thereby facilitating the use of the air gun and avoiding the existence of the high-pressure air pipe to limit the use of the air gun.
