[0002] Heptafluoropropane is a clean gas chemical fire extinguishing agent that mainly uses chemical fire extinguishing and also has physical fire extinguishing effects. Heptafluoropropane is colorless, odorless, low in toxicity, and non-conductive. It will not cause damage to property and precision facilities. The fire extinguishing mechanism is mainly to interrupt the combustion chain, and the fire extinguishing speed is extremely fast, which is beneficial for the rescue protection of precision electronic equipment and valuables.

[0003] The publication number in the existing public technology is: CN220237615U. A heptafluoropropane fire extinguishing device includes: a fixed frame; a sliding cavity, the sliding cavity is opened inside the fixed frame; a handle, the handle is arranged on the inner side of the sliding cavity, and a nozzle is fixedly installed on one end of the handle; a support assembly, the support assembly includes a mounting ring, a connecting rod, a spring, a rotating rod and a moving ring, the surrounding of the mounting ring is rotatably connected to the connecting rod, one side of the connecting rod is rotatably connected to the rotating rod, and one end of the rotating rod is rotatably connected to the moving ring. The heptafluoropropane fire extinguishing device provided by the utility model cooperates with each other through structures such as a handle, a mounting ring, a connecting rod, a spring, a rotating rod, a moving ring, a tin foil layer and a supporting layer. When in use, after the handle is pulled out from the inner side of the sliding cavity, the support assembly can automatically open the protective assembly, so as to protect the user's hands and prevent burns when extinguishing the fire.
