Description

technical field [0001] The invention relates to a small hand tool for escape, in particular to a pen-type safety glass breaker. Background technique [0002] Most of the doors and windows of public transport vehicles such as existing automobiles, trains, and ships are sealed with glass. In the event of a dangerous situation (such as fire, explosion, falling into the water, etc.), personnel escape will become an important issue. At present, safety hammers are mostly used, but the safety hammers on public transport are often engaged on the matching decks. It is not easy for people to take out the safety hammer when they are in a panic. Raise the safety hammer so that there is an effective distance between it and the glass window to smash the glass. For example, in a crowded and panic situation, raising the safety hammer can easily cause accidental injury; Enough force to break a car window is also still a big problem. Furthermore, it is impossible for citizens to carry a hea...
