Is it necessary to put a safety hammer in the car?

It is necessary to put a safety hammer in the car. The car safety hammer is one of the tools that many car owners will ignore. It can save the lives of people in the car at critical moments! And now the safety hammer has more and more functions. In the case that the seat belt cannot be unfastened, there will be a sharp knife embedded at the other end of the safety hammer to cut off the seat belt for self-rescue.

Introduction to car safety hammer:

The life-saving hammer, also known as the safety hammer, is an auxiliary escape tool installed in a closed cabin. It is generally installed in a place that is easy to get in a closed cabin such as a car. When there is a fire or falls into the water in a closed cabin such as a car, it can be easily taken out and the glass windows and doors can be smashed to escape smoothly.

How to use the life-saving hammer:

It mainly uses the conical tip of the life-saving hammer. Since the contact area of the tip is very small, when the hammer is used to hit the glass, the pressure on the glass at this contact point is quite large (this is somewhat similar to the principle of a thumbtack), and the car glass is subjected to a large external force at this point and slightly cracked.
