　　What are the power tools?

Electric tools have the advantages of easy portability, simple operation, and diverse functions. They can greatly reduce labor intensity, improve work efficiency, and realize mechanization of manual operations. Therefore, they are widely used in construction, housing decoration, automobiles, machinery, electricity, bridges, gardening and other fields. , and enter households in large numbers. So what exactly are power tools?

Classification of power tools

1. Electric drill: A tool used for drilling holes in metal materials, plastics, etc. When equipped with a forward and reverse switch and an electronic speed control device, it can be used as an electric screwdriver. Some models come with rechargeable batteries.

2. Electric hammer: used for drilling masonry, concrete, artificial or natural stones, etc. The functions of the electric hammer are interchangeable with those of the electric drill. Light drills widely use SDS-PLUS drill chucks and drill bits, medium and heavy hammer drills are replaced by SDS-MAX chucks and drill bits, and chisels can be clamped.

3. Impact drill: An electric tool mainly used for drilling hard materials such as masonry and concrete. When the impact mechanism is closed, it can also be used as an ordinary electric drill.

4. Grinder: A tool that uses a grinding wheel or disc for grinding wood. There are straight electric grinders and electric angle grinders. Sandpaper is required.

5. Jigsaw: Mainly used for cutting steel, wood, plastic and other materials. The saw blade reciprocates or swings up and down. It is most suitable for cutting precise straight lines or curves.

6. Angle grinder: Also known as grinder or disc grinder, it is mainly used for grinding steel, metal and stone. Commonly used grinding disc diameters are 100mm, 125mm, 180mm, and 230mm.

7. Cutting machine: It is mainly used to cut aluminum materials, wood, etc. at different angles. It is divided into metal material cutting machine and non-metal material cutting machine. When using it, pay attention to tightening the saw blade and wearing goggles.

8. Electric wrenches and electric screwdrivers: Electric wrenches and electric screwdrivers are used for loading and unloading threaded connections. The transmission mechanism of the electric wrench consists of a planetary gear and a ball spiral groove impact mechanism. Electric screwdrivers use a tooth clutch transmission mechanism or a gear transmission mechanism.

9. Concrete vibrator: used to tamp concrete when pouring concrete foundations and reinforced concrete components. Among them, the high-frequency disturbance force of the electric direct-coupled vibrator is formed by the motor driving the eccentric block to rotate. The motor is powered by a 150Hz or 200Hz medium-frequency power supply.

10. Electric planer: used for planing wood or wooden structural parts. It can also be used as a small bench planer when installed on a bench. The cutter shaft of the electric planer is driven by the motor shaft through a belt.

11. Marble machine: Generally used for cutting stone, you can choose dry or wet cutting. Commonly used saw blades include: dry saw blades, wet saw blades, and wet and dry saw blades. Home decoration is used for cutting wall and floor tiles.
