Q:Why hand grinding sand turbine, electric drill, impact drill and other power tools plug is two, plug is not three plug

Each of these devices has a "back" logo indicating double insulation protection, and the double insulated layer forms insulation protection between the outer shell and the inner part of the tool, thereby preventing the occurrence of electric shock. So no three plug in,

Q:How are the I, II, and III classes of power tools classified?

In accordance with the electric shock protection methods, electrical equipment is divided into the following 4 categories:0 category. The device relies solely on basic insulation to prevent electric shocks. There are no ground terminals on the live conductors of the 0 types of equipment.

Q:What other tools are there for the furniture except the pistol hole?

It is mainly used in construction, decoration, furniture industry, opening for objects or objects in the past, also known as hammer in some industries.Well, there are more drilling tools on the market now.

Q:Compared to pneumatic tools, what are the advantages of electric tools?

The pneumatic tool is more environment-friendly, energy-saving, and has better environmental adaptability, and is safer than an electric tool. The pneumatic tool has the advantages of simple structure, convenient operation, long service life and convenient maintenance

Q:What are power tools?

There are many kinds of power tools! Hammer, impact drill, electric scissors, electric planer, grinder, plastic welding gun, pistol drill, electric iron, curve sawing machine and so on, there are a lot of marble.

Q:What are the commonly used rotor types for power tools?

Concrete vibrator: concrete used for pouring concrete foundations and reinforced concrete members to eliminate porosity and increase strength. The high-frequency disturbing power of the electric direct acting vibrator is driven by an electric motor to rotate the eccentric block, and the motor is powered by an 150Hz or 200Hz intermediate frequency power supply.The planer: used for planing wood or wood structure, mounted on the bench can be used as a small bench plane. The planer cutter shaft by the motor shaft through the belt drive.

Q:Is BOSCH's power tools good or MAKITA's power tools?

BOSCH electric tools three characteristics:1. 、 light structure, easy to carry and use.2. more than manual tools can increase labor productivity several times to several times;3., the utility model has the advantages of high efficiency, low cost, small vibration and easy control.

Q:What is the working principle of power tools?

AC motor, AC motor of induction motor, its strong induction current (eddy current) magnetic field generated in the rotation of the magnetic force on the rotor copper bar, continuous cutting, according to Lenz's law, the induced current has the effect of relative motion occurs against the rotor magnetic field and the rotor is, with the magnetic field and rotation. But the rotor rotation speed of the high speed magnetic field does not transform, otherwise it will not be able to cut the copper lines.

Q:What kind of material does the power tool case have?

The outer shell is a physical structure, and the enclosure uses support, connecting motors, transmission mechanisms, switches, handles, and attachments to make it the complete outer structure of a complete power tool entity.

Q:Power tools are power tools?

Divided into electric, pneumatic, gasoline tools, currently on the market these 3 main types. I've been a tool for over 10 years
