functional classification
1. Ordinary screwdriver: It is a screwdriver with the head and handle built together. It is easy to prepare and can be used as long as it is taken out. However, since there are many different lengths and thicknesses of screws, sometimes it is necessary to prepare many different screwdrivers.
2. Combination screwdriver: a screwdriver that separates the screwdriver head and the handle. When installing different types of screws, you only need to replace the screwdriver head, 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 screwdriver bit.
3. Electric screwdriver: Electric screwdriver, as the name suggests, uses an electric motor to install and remove screws by hand, usually a combination screwdriver.
4. Clock screwdriver: It is a precision screwdriver and is commonly used in the repair of wrist-type clocks, so it is called this.
5. Small diamond screwdriver: The head handle and body length are smaller than the commonly used screwdrivers, not a clock screwdriver.
In terms of its structural shape, there are usually the following types:
1. Straight. This is the most common one. The head model has a character, a cross, a rice character, a T-shaped (plum-shaped), an H-shaped (hexagonal) and so on.
2. L-shaped. More common in hexagonal screwdrivers, using its longer stem to increase the torque, thus saving more effort.
3. T-shaped. There are many applications in the auto repair industry.
