Emergency rescue: When a vehicle door cannot be opened due to pressure deformation or high water pressure, the emergency car window breaker can break the window and cut the seat belt for a quick escape. It does not rely on physical strength to break the glass, allowing effective use even under water pressure. Knife feature: The window breaker includes a built-in knife at the end of the handle, designed to prevent accidental injury. In situations where the seat belt is jammed and cannot be released, the integrated seat belt cutter allows for fast cutting and immediate escape. Compact and portable: This emergency car window breaker features a modern, compact design. The safety hammer is fully functional, equipped with a seat belt cutter and strong enough to break tempered glass and cut seat belts quickly during emergencies. Easy to use: Designed with a built-in high-pressure spring mechanism, the tool breaks windows with minimal effort through a precise impact point. Combined with a concealed seat belt cutter, it enables quick operation by anyone, including elderly individuals and women. Safety upgrade with advanced technology: The newly developed striking mechanism enhances window-breaking efficiency, improves overall durability, and ensures reliable performance in critical situations.
