Therefore, the conventional toy gun chamber structure has its own shortcomings. Therefore, the present invention proposes a composite air chamber. The structure is designed to allow the user to freely select the source of the high pressure gas when operating the toy gun. The composite air chamber structure is placed in the gun body of the toy gun and can be used as a filled high pressure gas for the gun power (propane C3H8, refrigerant). R134A) storage tank can also be used for the disposal of disposable high-pressure gas cylinders (CO2 Chargers). The composite air chamber structure includes a barrel body combined with an upper fixing member and a base, and the upper fixing member is coupled to the base of the gun body. To fix the entire air chamber structure to the gun body, and the upper edge of the upper fixing member is further engaged with a piercing member to make a gas path with the gun. Connected to receive the high-pressure gas delivered from the barrel, a sleeve can be accommodated in the barrel to match the CO2 Chargers of different outer diameters, and the base with the filling nozzle can be replaced. The high-pressure gas is directly poured into the barrel to greatly enhance the convenience of use.
