A car escape window breaker

technical field

The utility model relates to a tool, in particular to a vehicle escape window breaker.

Background technique

In order to help passengers escape under special circumstances, most vehicles are equipped with a safety hammer.

When smashing windows, passengers need to have a lot of space to press and swing the safety hammer. However, the space in the car is small and people panic in emergency situations. , may not work.

2. The strength of smashing the window with a hammer depends entirely on the passenger's personal factors: a large part of the effect of smashing the window depends on the passenger's personal arm strength, which is not conducive to female passengers.

3. The drop point of the window smashing hammer depends on the passenger's grasp, and the maximum use effect of the safety hammer cannot be fully utilized. Smashing the window needs to smash the four corners or the midpoints of the four sides of the tempered glass to get good results. Smashing the middle of the window is ineffective. However, in an emergency, passengers often cannot calmly judge and subconsciously smash the middle of the window. cause more confusion.
