　　Reasons why handheld power tools are prone to electric shock accidents？

The reasons why there are many electric shock accidents with hand-held power tools are as follows:

1. Handheld power tools operate under the tight grip of a person, and the resistance between the person and the tool is small. Once the exposed part of the tool is charged, a large current will pass through the human body, which may easily cause serious consequences.

2. Handheld power tools operate under the tight grip of a person. Once an electric shock occurs, it is difficult to get rid of the charged object due to muscle contraction, which can easily cause serious consequences.

3. Handheld power tools are very mobile, and the power cord is easily stretched and worn, causing leakage. The connection point of the power cord is easy to fall off, leaving the metal shell charged, leading to electric shock accidents.

4. Handheld power tools are very mobile and may be moved under harsh conditions. They are easily damaged and the metal casing becomes charged, leading to electric shock accidents.

5. Small handheld power tools use 220V single-phase AC power supply, powered by a phase line and a working neutral line. If the phase wire is mistakenly connected to the metal shell or the protective neutral wire is mistakenly disconnected, the metal shell will be charged and lead to an electric shock accident.
