1 Use of safety hammer

 The life-saving hammer is actually mainly the use of its conical tip, because the contact area of the tip is very small, so when using the hammer to smash the glass, the contact point on the glass pressure (not pressure oh, but the pressure on the unit area) is quite large, which is somewhat similar to the principle of the thumbtack, the film is easily punctured, And the car glass at the point is subjected to a lot of external forces and produce a slight cracking, and for tempered glass, a little cracking means that the stress distribution inside the whole piece of glass is damaged, resulting in countless spider mesh cracks in an instant, at this time as long as the hammer gently hit a few times can remove the glass debris.

The middle part of the tempered glass is the strongest, and the corners and edges are the weakest. The best way is to use a safety hammer to hit the edges and corners of the glass, especially the middle of the top edge of the glass, once the glass has a crack, you can knock a few more times. It is said that about 2 kilograms of pressure can break the corners of the tempered glass

 If there is no safety hammer, women's high heels are also a very good thing, the heel swung up to make the strength to hit it, the finer the heel the better!

2. Pay attention to:

 If you take a long bus, it is best to choose a place close to the safety door or roof safety exit. If you want, you can carefully read the instructions on how to open the safety door, because in the event of an accident, you will not be able to calm down to read the instructions.

Product features:

This product is very excellent in appearance design and quite commendable: it is more humane and more in line with actual needs compared with general similar products. For example, the end of it is an extended hook, and unlike some products, this part does not protrude, and the handle is generally the same, which increases the difficulty of emergency use. Just think, in an emergency, how many people will calmly align their seat belt with the gap in the cutter? This product of ours is much more convenient to use. In an emergency, as long as people wave it towards the seat belt, its protruded hook will naturally hook the seat belt, and make the seat belt slip into the gap cutter. In addition, its base design makes the products on it very stable and fixed, and will not fall off despite the car bumps. It can be removed very easily.
