ONE BLOW / Broken windows machine


Many people die each year because they are trapped in cars and unable to break Windows, and today's window breakers either require hard hammering or are prone to damage over time, leading to tragedies.

In this device, the firing pin structure of the ballpoint pen is redesigned, and the limiter is divided into two parts, which can control the starting of the firing pin. When the starting device is pressed, the internal firing pin can be driven to impact.

The new structure of the device makes it more stable and durable, and it is not easy to be damaged. It's structural innovation design.
