Background technique

When people use cars, they always equip some emergency escape tools for vehicles to prevent accidents, such as hammers used to break glass, cutting blades used to cut or cut seat belts, flashlights for lighting, etc. The emergency tool used has a gun-shaped body with a handle and a base. The hammer body is fixed at one end of the body. When not in use, the body is fixed on the base. When in use, the body is removed from the base, the handle is gripped, and the hammer is The head is aligned with the window glass, and the tapping action is like a knife-cutting wave. However, this emergency escape tool has only a single function and needs to be equipped with other emergency escape tools, so that there are so many equipment to be placed. The tool requires a large space, which is easy to take up the limited space in the car, and it is also troublesome to use.

If the car falls into the water, it is at a critical juncture, time is very precious, if you can save time, you can increase the chance of escape. The commonly used emergency escape tools need to be taken out one by one, it is a waste of time, the car falls into the water. At the time, the interior of the car is darker. The lighting device of the car itself will be ineffective due to the inflow of water, which will cause insufficient light in the car. It will be more troublesome when looking for tools. This will waste time, and the common emergency tools will use the wave when breaking the glass. The way, in a small space, the breaking force caused by waving emergency tools is not enough, it is not easy to break the glass, and some glasses have higher strength, are less prone to breakage, and delay the escape timing.

On November 12, 2003, the Chinese Patent Office announced a CN2585786Y patent entitled Emergency Emergency Tools for Vehicles, including a gun-shaped body, a base, a handle on the body, and a hammerhead at one end of the body. The body is provided with a warning device, a power supply and a magnetic control switch, and the magnetic control is opened. The reed switch in the control device control circuit and the magnetic conductive member fixed on the corresponding position of the base are used. When the tool escapes, the glass is broken by waving, the power of the wave is not great, and the glass is not easily broken. And there is no lighting device, and there will be no way out when in the car.
