Description

Technical field [0001] The invention relates to equipment in the field of fire protection, in particular to a fire hammer for fire safety. Background technique [0002] The safety hammer is an auxiliary escape tool installed in a closed cabin. It is generally installed in an easily accessible place in a closed compartment such as a car. When there is a fire or falling into the water in an enclosed compartment such as a car, it can be easily taken out and broken glass windows and doors to escape smoothly. It mainly uses the conical tip of the life-saving hammer. Because the contact area of ​​the tip is small, when the glass is hit with a hammer, the pressure of the contact point on the glass is quite large, and the car glass is subject to a large external effect at this point Force and produce slight cracking. For tempered glass, a little cracking means that the stress distribution inside the whole piece of glass has been destroyed, resulting in countless spider web-like cracks...
