The structure and principle of the police electric stick consists of a high voltage source (also known as a high voltage generator), a high performance battery (nickel cadmium or nickel hydrogen battery) and an electric shock head. Most of the new electric batons are pulse type. And most of them are made of special plastic, which will not cause electric leakage.

The telescopic baton is a necessary weapon for China's front-line public security officers. It has a wide range of functions, strong aggressiveness, easy to carry, and tight defense. It can not only effectively stop violence, but also be used to block, cut, and stick, and thus forms a variety of telescopic baton defense techniques.
