First．Semi automatic electric screwdriver

　　1、The driver that will not automatically brake after reaching the set torque is called semi-automatic electric driver. Generally, semi-automatic design is manual.

　　2、The semi-automatic series voltage is divided into AC high-voltage direct plug-in type and DC low-voltage type after power transformation.

Second．Full automatic electric screwdriver

　　1．The electric screwdriver that can fully automatically brake and stop running after reaching the set torque is called the fully automatic electric screwdriver.

　　2．The fully automatic electric screwdriver is divided into two series: AC high voltage and DC low voltage. According to the different starting modes, it can be divided into two types: manual type and push down type.

　　3、The characteristics of high-voltage series are that it does not need a separate power supply to convert the voltage, and it is directly connected with the mains power, so the operation is fast and takes up less space.

　　4、Compared with high-voltage series, low-voltage electric screwdriver has the following advantages: small size and light weight, low-voltage DC motor drive, long life and high safety factor.

Third．Hand operated electric screwdriver

　　To operate the startup mode, press and hold the startup lever or pressing plate button with your finger.

Fourth．Down pressing electric screwdriver

　　To operate the startup mode, it is not necessary to press and hold the startup lever or the pressing plate button with your finger. It can be started by directly aligning the workpiece and pressing.
