[Background technique]

The pneumatic air gun is a pre-compressed air type air gun (PCP). It combines the advantages of multiple pumping and single pumping types, and its launching power can be high or low and adjustable. When shooting, take the insurance down and apply pressure to the trigger until the trigger buckle is released. At this point, the hammer advances rapidly by the power of the hammer spring, and the air in the air compression chamber is suddenly pushed to the lead on the back of the barrel to fly out of the barrel and hit the target.

At present, pneumatic air guns on the market have been widely used. The applicant has optimized the existing pneumatic air guns to optimize the design and performance of the existing PCP in the market. E.g:

1. At present, when steel bombs are used on domestic and foreign air guns, the steel bullets are placed in the gun body, or the spring is pressed into the gun body, which is inconvenient to carry and inconvenient to enter.

2. At present, the domestic air gun cannot adjust the bullet speed, which is inconvenient to use.

3. At present, the venting valve assembly widely used in the market uses steel-to-steel or steel-to-hard rubber in the sealing part, and its sealing has a certain air leakage ratio, and its hard rubber sealing is not it is good.

4. At present, there is a lever type bolt structure on the market, which is not convenient for direct shooting of steel bullets.

5. At present, there is only one air intake hole in the barrel at home and abroad, which affects the efficiency of intake air and is not conducive to improving the initial velocity of the bullet.

6. At present, there are various fixing structures in the market, and the structure is complicated and the cost is high. The magazine is easy to install and is not easy to find, which affects normal shooting.
