The working process of BB gun
- Mar 27, 2018 -

When the bolt slips back, it opens the cartridge inlet, allowing the BB (or paintball) to fall into the barrel. The bottom of the hammer is a small machine spring that is used to hold the bolt when the bolt is resisting the hammer.

This connects the bolt and the hammer so that the two can move as a whole. After the bolt is pulled back, the archer moves it forward (along with the hammer). When shooting, the shooter just pull the trigger. The trigger pushes upward to the rear of the machine spring, causing the front of the machine spring to sink. In this way, the hammer is detached from the bolt, and then the spring quickly pushes the hammer backwards. When the hammer moves backwards, it pushes the protruding circular pads on the valve tube, pushing the valve tube to move backwards, at which point the explosive force produced by the Hammer is far greater than the forward thrust produced by the rear spring and air pressure. The valve tube moves backwards in an instant, and the spring bounces back to its original position. During this time, the opening of both ends of the valve tube opens and the compressed gas enters the barrel through the valve tube. The strength of this explosive force is enough to push the projectile forward at a very fast rate.
