The idea of innovation development tool is convenient, efficient, environmental protection principle. Such as Screwdriver Bits for electric screwdriver. Alternating current tools early although power is strong, but when used outdoors must have enough power line, very inconvenient. It later developed a gasoline-powered tools, but the price is expensive, large weight, noise Yan, not environmental protection, winter engine problems.
And the lead acid batteries, nickel-cadmium, nickel zinc batteries because of its heavy weight or quantity is not enough and other reasons gradually eliminated. But the lithium battery tools now have solved the above problems, this type of battery of portable and durable, has been widely used in every field. Gold mould electrical network chief analyst Luo Baihui thinks, innovation must first solve the problem of real life. For example, in the nail, a lot of people have been the right hand left hand hammer to experience, but now has a mace, no longer just the case, a 6 inch long nails, just seven or eight seconds into the wood, the price of this tool in the United States is 70 dollars, although compared with an ordinary hammer, its price is more expensive, but it can solve the nailing working in confined spaces, such as under the table or in the drawer nailing, use this tool only.
