<p>In 1895, German Overtone produced the world's first DC electric drill. The shell is made of cast iron and can drill 4mm holes in the steel plate. Then a three-phase power frequency (50Hz) electric drill appeared, but the motor speed failed to exceed 3000r/min. In 1914, electric tools driven by single-phase series motors appeared, and the motor speed reached more than 10000r/min. In 1927, an intermediate frequency electric tool with a power supply frequency of 150 to 200 Hz appeared. It not only has the advantages of a single-phase series motor with high speed, but also has the advantages of a simple and reliable three-phase power frequency motor. However, it needs to be powered by an intermediate frequency current. , Use is restricted.</p><p><br></p><p>An <a href="https://www.worksitetool.com" rel="noopener noreferrer" target="_blank">electric tool</a> is a mechanized tool that uses a motor or an electromagnet as the power and drives the working head through a transmission mechanism. According to the "Classification of National Economic Industries" (GB/T4754-2011), the company's industry belongs to the sub-category "Pneumatic and Electric Tool Manufacturing" (code C3465), which is a sub-category of "General Equipment Manufacturing". Power tools are mainly divided into metal cutting power tools, grinding power tools, assembly power tools and railway power tools. Common power tools are electric drill, electric grinder, belt machine, electric wrench, electric screwdriver, electric hammer, concrete vibrator, electric planer, angle grinder, electric saw, grinder, angle grinder, blower, polishing Machine, sanding machine, etc.</p><p><br></p><p>The upstream industries of power tools are suppliers of raw materials (such as silicon steel sheets, enameled copper wires, aluminum parts, plastics, etc.), and the industry is more sensitive to price changes of the above-mentioned raw materials. The application areas of power tools include road construction, decoration, wood processing, metal processing and other manufacturing industries. Affected by the state's policy of stimulating domestic demand and increasing investment in infrastructure, the future development prospects of the construction road and metal processing industries are promising, which will drive the increase in demand for the power tool industry.</p><p><br></p><p>In 2016, the total industrial output value of my country's power tool industry was 48.247 billion yuan, a year-on-year increase of 3.14%. In 2017, the total industrial output value of the power tool industry reached 49.989 billion yuan, a year-on-year increase of 3.61%. Relatively speaking, the growth rate of the output value of electric tools is relatively slow. In 2016, the sales volume of China's power tool industry was 239,699,400 units, a year-on-year increase of 3.29%. In 2017, the total sales volume reached 246,304,700 units, a year-on-year increase of 2.76%. Since more power tools are exported in my country, the following sales data include the number sold abroad.</p><p><br></p><p>my country's electric tool industry presents the following characteristics and development trends: (1) The industry growth rate is stable. (2) There is a gap in technology level, and the production capacity of key parts is low. (3) The profit margin is reduced. (4) Lack of brand. In response to the current situation and problems of these industries, my country’s power tool companies need to focus on the following aspects: 1) need to strengthen brand awareness, improve international competitiveness, and obtain due profits; 2) continuously improve product quality and added value, research and development New products; 3) At the same time, actively explore emerging markets such as Africa and Latin America to achieve market diversification. The domestic power tool market is more critical of the quality and brand of power tools. Therefore, the market is increasingly inclined towards good-quality, good-brand power tools.</p>
