Problems solved by technology

Such as authorized announcement number is CN105999572A "A kind of multi-functional vehicle window breaker", CN206566367U "A kind of window breaker and the device using the breaker", etc., these window breakers provide emergency escape when the bus has an accident Useful tools, but they have a common defect. When danger comes, you need to find a window breaking tool, and because the provided window breaking device is relatively small, and the hardness of the ejection spring is very strong, it is difficult for the elderly and children to use it normally, even adults It is difficult for people to break the tempered glass to escape and save themselves if they are not strong enough or use the wrong method; especially when the vehicle is tilted and overturned at 90 degrees, it is difficult for passengers to get the window breaker. Use a window breaker to knock on the tempered glass placed on top

There is a portable window breaker in the prior art, which is small and portable, but it needs to fire the device to break the window.
