1. Ordinary screwdriver

It is a screwdriver made of the head handle, which is easy to prepare and can be used as long as it is taken out, but because there are many different lengths and thicknesses of screws, sometimes it is necessary to prepare many different screwdrivers.

2. Combined screwdriver

A kind of screwdriver that separates the screw head from the shank, and when you want to install different types of screws, you only need to replace the screw bit, and you do not need to bring a large number of screwdrivers. The advantage is that it can save space, but it is easy to lose the screw bit.

3. Electric screwdriver

Electric screwdrivers, as the name suggests, are installed and removed by hand with electric motors, usually combined screwdrivers.

4. Clock driver

It is a precision driver, commonly used in the repair of hand-strap clocks, so it has this name.

5. Small King Kong screwdriver

The head handle and length are smaller than the commonly used screwdrivers, and are not watch drivers.

In terms of its structural shape, there are usually the following:

1. Straight. This is one of the most common. The head model has a word, cross, beige, T type (plum type), H type (hexagon), etc

2. L-shaped. It is more common in hex screwdrivers, whose longer rod is used to increase the torque and thus reduce effort.

3. T-shaped. There are many applications in the auto repair industry.
