The emergence of electric tools has changed the way humans produce

With the continuous progress of technology, more and more electric tools have emerged to improve work efficiency and replace heavy physical labor. It is no exaggeration to say that the emergence of power tools has changed the face of the world. Tools are tools that give humans mechanical advantages. In the animal world, many birds and primates also use tools, but there is one thing that sets us apart from them: power. Unlike other animals in the animal kingdom, we humans not only rely on physical strength, but can also use other energy sources to drive tools.

How to purchase electric tools Introduction to purchasing tips for electric tools

1) Firstly, the difference should be based on one's own needs, whether it is for home use or professional use. Generally, the difference between professional and general household electric tools is mainly in terms of power. Professional electric tools have higher power, while general household tools have lower power and smaller input power. Highly integrated electric tools have a higher convenience of use than large and single function products. Therefore, it is recommended to choose electric tools with rich functions, compact size, simple structure, and easy storage. When purchasing electric tools, it is necessary to choose clear and undamaged external packaging. The appearance of the electric tools should be normal, the plastic parts should be intact, without obvious shadows or dents, scratches or bumps, the relevant coatings should be smooth and beautiful without defects, the surface of the entire machine should be free of oil and stains, and the handle of the switch should be flat, The length of wires and cables is generally not less than 2M. The relevant markings of electric tools are clear and complete, with parameters, manufacturer, and certificate of conformity. The tools should be held by hand, connected to the power supply, and frequently operated to make the tools start frequently. Observe whether the on-off function of the tool switch is reliable, and whether it affects the television/fluorescent lights on site, in order to determine whether the tools are equipped with anti-interference suppressors. The electric tools should be powered on and run for 1 minute, Feel the vibration and observe if the reversing spark, air inlet, etc. are normal.

Precautions for using handheld electric tools

The power cord of Class I tools must use three core (single-phase tools) or four core (three-phase tools) multi stranded copper core rubber sheathed wires, and the yellow and green dual color wires can only be used as protective grounding or neutral wires in any case.

Place of use for handheld electric tools

In general places with an air humidity of less than 75%, Class I or Class II handheld electric tools can be selected, and the connection points between the metal shell and the PE line should not be less than 2; Except for Class II tools with plastic casing, the rated leakage current of the leakage protector in the relevant switch box should not exceed 15mA, and the rated leakage action time should not exceed 0.1s. The load line plug should have dedicated protective contacts. The structure of the socket and plug used should be consistent to avoid mixing conductive and protective contacts.
