Electric screwdriver, also known as electric screwdriver and electric driver, is an electric tool used to tighten and unscrew screws. The electric tool is equipped with a mechanism for adjusting and limiting torque, which is mainly used in the assembly line and is one of the necessary tools for most manufacturers.

Before plugging in the power supply, the switch should be positioned in the off state. Pay attention to whether the power supply voltage is suitable for the use of the machine. When the electric screwdriver is not in use or the power is off, the plug should be turned off. When using, do not set the torque adjustment too large. When replacing the screwdriver head, be sure to pull the power plug away from the power socket and turn off the power of the screwdriver. Do not drop or hit the electric screwdriver during use.
