A portable fire extinguishing apparatus, which comprises a casing (20) and a cartridge (3) arranged inside the casing (20). The top end of the cartridge (3) is fixedly connected with the casing (20) through a snap ring (24); the bottom of the cartridge (3) is fixedly connected with the casing (20) through some nuts and bolts; and an explosion venting unit (2) is arranged at the jet end of the cartridge (3).
