The stun gun, also known as STUN GUN abroad, is a prohibited item in China, and it is forbidden to produce, sell, and hold. Therefore, the current civilian self-defense equipment is generally designed in the shape of a stick, similar to a flashlight, commonly known as an electric rod, but the principles of the two are similar, but the appearance is different.
The stun gun first appeared in science fiction novels in the early 20th century, and some people called it "electric shock gun" according to its principle. The gun has no bullets, it uses charged "darts" to subdue the target. Inside the gun is a pneumatic magazine filled with nitrogen. After pulling the trigger, the high-pressure nitrogen in the magazine is quickly released, launching the two electrodes in the barrel; after hitting the target, the barb can hook the suspect's clothes, and the battery in the barrel is through insulated copper wire The release of high pressure caused the criminals to convulse and shrink into a ball.
