Air gun using high-pressure gas

Abstract

This invention discloses an air gun using high-pressure gas, relating to the field of air gun technology. The air gun using high-pressure gas includes a first body, a valve assembly, and a drive assembly; a valve stem is slidably inserted into the valve body along a first direction; a first elastic member has an elastic restoring force that pushes the hammer toward the valve body and pushes the valve stem to move along the first direction; an electric drive assembly is connected to the hammer and can drive the hammer to intermittently move away from the valve body in the first direction. This air gun using high-pressure gas uses the electric drive assembly to drive the hammer to intermittently move away from the valve body, thereby achieving a stable reset of the hammer.
