[0002] Fire hoses and protection shields are indispensable equipment for fire fighting and rescue. Usually, the protection shield and the fire hose are two independent pieces of equipment. At the fire rescue scene, we can often see the scene of firefighters wearing fireproof clothing and holding a fire extinguishing hose to extinguish the fire. The fire extinguishing hose is a water outlet pipe. There is no protective facility in front of the firefighters. Both the people and the hose are exposed to the fire scene. When the fire intensifies and the high-temperature heat wave attacks, the firefighters are easily burned; especially when unexpected secondary disasters such as explosions occur at the fire scene, it seriously threatens the personal safety of the firefighters.

[0003] The patent with the patent number CN 220477995 U discloses a fire hose with a protection shield, which includes a shield body 1 and a fire hose 2. A connecting pipe is penetrated through the shield body 1. The fire hose 2 includes a nozzle 21 and a hose body 22. The connecting pipe connects the nozzle 21 and the hose body 22 in communication. The front end of the hose body 22 and the rear end of the connecting pipe are hermetically connected. A detachable component is provided between the rear end of the nozzle 21 and the front end of the connecting pipe. Although this patent solves the problem that the fire hose has no shield, when in use, the hose needs to be assembled onto the shield, and multiple nozzles with different water output volumes need to be prepared, which is not convenient to use. The shield is still in the traditional form with a fixed size, and the whole device occupies a relatively large space. Summary of the Invention
