The rectangular protrusion is made of high-strength pure titanium alloy, with distinct edges and corners and a hardened surface, providing strong impact force. The protrusion is hidden inside the buckle and controlled by a dual-safety telescopic structure. It can only be ejected by simultaneously pressing the side lock and the top button. This design not only prevents accidental activation in daily use but also enables quick deployment in case of danger. The sharp edges and hardness of the rectangular protrusion can deter and defend against potential threats.
The buckle is designed with standard dimensions that fit perfectly into the passenger seat belt buckle slot, ensuring a secure and firm fit. The one-handed operation mechanism is specifically optimized. A large, ergonomic arc-shaped unlocking button is set on the side of the buckle. With just a light press of a finger, the buckle can be instantly released. Even in a panicked and tense emergency, it allows for easy one-handed operation, enabling quick escape.
The quick-release structure allows for easy removal from the seat belt buckle slot. It can be conveniently attached to daily items such as backpacks and keychains, extending its protective function from inside the car to various outdoor scenarios.
