Firefighters should quickly escape from the scene of fire when they encounter a very large fire and cannot control it. When firefighters need to escape from a trapped scene in a high building, the firefighters are generally tied in a room by using a portable high-altitude escape quick descent rope, and then exit from a window for quick descent escape. However, in all fire sites where firefighters need to escape, the fire is very large and the temperature is very high, and the high-altitude escape quick-descent rope is not high-temperature-resistant although the strength is very high, so that the rope is easy to blow in a short time. This may cause the fire fighter to fall down and endanger life safety when the high-altitude escape quick-descent rope has been blown out when the fire fighter is not falling to the ground. In addition, the existing portable multifunctional fire axe has a very short axe handle (about 20 cm), but is made of a solid steel bar, so that the components of the fire axe are very heavy. When the fire-fighting backpack is carried in the fire-fighting backpack, the fire-fighting backpack consumes the physical strength of the firefighters and affects the flexibility of the actions of the firefighters, which is very inconvenient. And when encountering a place needing to be broken and detached, the handle is very difficult to exert force due to the short handle.
