Technical Field

Background
The electric shock gun is also called as a Tase gun, because the electric shock gun is developed and manufactured by Tase International company, belongs to prohibited articles in China, and is prohibited to be produced, sold and held, at present, civil personal defense equipment is generally designed into a stick shape, is similar to a flashlight and is commonly called as an electric wand, and the principle of the electric shock gun and the electric wand is similar but the appearance is different. Electric shock guns were first developed in the scientific novelties in the early 20 th century and are also called "electric guns" according to their principle. After the electric shock gun hits the target, the barb of the electric shock gun can hook the clothes of a criminal suspect (target), and the battery in the gun chamber releases voltage through the insulated copper wire to enable the criminal to spasm muscles throughout the body and contract into a group.
The inner core of the electric shock gun is a whole set of circuit system, the nerve of a human body is controlled by high voltage and low current, and the voltage output of the traditional electric shock gun is fixed, so that the value of the output voltage of the electric shock gun is the same no matter the law enforcement officer is at any age, at any gender and under any body health condition in the process of using the electric shock gun by the law enforcement officer. However, if the same person, different ages, different sexes and different physical health conditions are not available, different physiological mechanisms and different body impedance feedbacks can occur, and if a constant voltage electric shock gun is used, the human health can be damaged under special conditions. Therefore, when the existing electric stun gun with constant high voltage output is used for law enforcement, the law enforcement without fatality can not be really realized.
