The invention discloses a gas fire extinguishing device capable of adjusting working at any angle. The gas fire extinguishing device comprises a compressed gas cylinder and a fire extinguishing agentgas cylinder, the top of the compressed gas cylinder is provided with an electromagnetic driving compressed gas release valve, the top of the fire extinguishing agent gas cylinder is provided with a pneumatic driving container valve, a clapboard piston is arranged in the fire extinguishing agent gas cylinder, a bottom cover is arranged below the clapboard piston, an exhaust port and a wiring terminal head are arranged on the electromagnetic drive compressed gas release valve, the exhaust port is respectively connected with air inlet holes in the pneumatic driving container valve and the bottomcover below the fire extinguishing agent gas bottle through an upper pipeline and a lower pipeline, and the wiring terminal head is connected with a fire alarm control device. According to the gas fire extinguishing device, the compressed gas cylinder and the fire extinguishing agent gas cylinder are arranged, other power is not required to be externally connected by using compressed gas energy storage; the fire extinguishing agent gas cylinder is internally provided with the clapboard piston, the clapboard piston and container inner wall sealing and separating fire extinguishing agent and compressed gas pushing piston, so that the design of directly pushing the fire extinguishing by using a traditional siphon structure compressed gas is avoided.
