Portable fire extinguisher

摘要

A portable fire extinguisher includes a housing (3) and a cartridge (4) arranged within the housing (3). The cartridge (4) is fixedly connected at a bottom thereof to the housing (3) via a fastening device (40). This on the one hand facilitates shifting, and on the other hand allows the cartridge (4) to be fixed appropriately in the housing (3), thus not easily rotated or loosened, also, the need of a production site for waiting for silicone solidification by standing for seven to eight hours is avoided when silicone injection for fixing is used, thus improving production efficiency.
