1) When using hand-held electric scissors, it is usually quite sensational, and it is easy to cause insulation damage or structural damage to cause electric shock.
2) The power cord of the hand-held electric scissors is easy to wear at the -out part. Once the conductor of the core wire is exposed or touches the metal shell, it will cause electric shock.
3) The grounding (zero connection) maintenance of the metal casing fails to really work. If there is maintenance wiring at the plug, some of the sockets are not connected to the maintenance line, or the maintenance line itself is disconnected or disconnected from the terminal, it is easy to cause electric shock.
4) The east-west deactivation does not block the power supply or the mobile electrical equipment does not block the power supply when it is moving. The power cord is broken or crushed causing an electric shock.
5) The equipment itself has no disadvantages. When it is used, the situation of the construction site is unknown, and the electric shock is caused by the contact of the live wire with something. Such as perforating the wall, punching into the wiring laid in the dark, or punching the floor slab to the wire laid in the board hole, it is easy to cause electric shock.
6) These things or equipment are usually held tightly when used. Once an electric shock occurs, they may not be able to get rid of, and the result is more serious.
