With the continuous advancement of science and technology, more and more power tools are emerging to improve work efficiency and replace heavy physical work. It is no exaggeration to say that the emergence of power tools has changed the face of the world. Tools are instruments that give humans mechanical advantages. In the animal world, many birds and primates also use tools, but one thing that sets us apart from them is strength. 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.
We may not have superpowers, but we have power tools. Power tools cover all aspects of our lives, including medical treatment, manufacturing, construction, rescue, etc. During the Industrial Revolution in the 19th century, factories used gas, steam and electricity to give tools more power. Since the 1960s, people have once again transformed power tools so that they can be used in ordinary households. The global market share of power tools is US$23.4 billion. About 40% of them come from North America, 22% from Asia, and 27% from Europe, of which power tools account for about 75% of all power tools sold. Power tools account for approximately 75% of all power tools sold.
The power of a power tool depends on how much voltage it can withstand. Think of voltage as water pressure. The greater the pressure of water management, the stronger the water flow. The same goes for voltage, the more volts you have in a tool, the more power the tool can produce. Getting enough voltage also meant plugging in, but the discovery of batteries changed all that. Battery-powered tools were first used on the moon, in the 1960s. The Apollo astronauts needed a small handheld drill to drill into the lunar surface to collect soil samples, so engineers designed a special power tool battery pack. From then on, the cordless drill was born. This unique invention was first used in the handheld cordless vacuum cleaner launched in 1979. This later sparked a revolution in home power tools.
The power tools we know and use run on human energy, electricity, gasoline, and compressed air, but the tools used by professionals are much more powerful. In some car events, we often see racing maintenance personnel using pneumatic wrenches to remove tires. Because the event has time limits, they must race against time to save time. It only takes maintenance personnel 12 seconds to remove the nuts of the four tires, because the speed of this thunder gun wrench can reach 25,000 rpm in one minute. It is powered by compressed air, compared to a standard pneumatic wrench that rotates at 2,000 rpm. The speed of the thunder gun is 12.5 times that of them. At this speed, a tire nut can be removed in 0.2 seconds. If using a standard air wrench. Instead of a thunder gun, the 12 seconds it takes to change a tire will become three minutes.
