In fact, he said hardware tools is a very big concept, because it contains the content is very much, some common metal materials is defined by the method, through a certain physical and chemical reach is also a function of the metal utensils, general hardware tools can be divided. Is the tool of hardware, building hardware, daily hardware, lock hardware, kitchen hardware, Home Furnishing hardware, according to the current classification of words divided or very carefully, but at least is divided into two types of manual and electric operation form, today we see electric hardware tools.
In fact, electric tools, hardware tools is a form, but compared with the electric tools and manual tools it is very convenient, in the actual production of the machinery industry in general, we require is to improve work efficiency, efficiency can only meet the actual production tasks, to know the production the use of electric tools, the equivalent of artificial production several times. There is no available but here is not able to slander is hand tools, when a lot of manual tools not available nowhere, need a lot of industry is the manual operation of the fine work, only hand tools can be completed.
Simple example, general big nut or screw when tightened and fixed, this time the power is limited, so this time should use is mechanized operation, using electric tools, electric tools is charged, need to contact can be used, but for a relatively small number of electric tools, taking into account the carrying convenience, are used in rechargeable battery, install and use only when the need to replace the battery on the line at the scene.
The most common is the difference between a manual screwdriver and electric screwdriver, electric screwdriver to screw a screw in less than 3 seconds, but the manual may be 30 seconds, this gap may be separately without distinction, if the screw workload is large enough, the difference between is as can be imagined.
