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.

We may not have superpowers, but we have power tools. Power tools cover all aspects of our lives, including production, manufacturing, construction, rescue, and more. In the 19th century industrial revolution, factories used gas, steam, and electricity to give tools more power. Since the 1960s, people have once again transformed power tools to be used in ordinary households. The market share of power tools is 23.4 billion US dollars. About 40% of them come from North America, 22% from Asia, and 27% from Europe, with electric tools accounting for about 75% of all sold power tools. Electric tools account for approximately 75% of all sold power tools.

The power of electric tools depends on how much voltage they can withstand. You can think of voltage as water pressure. The greater the pressure of water management, the stronger the water flow will be. The voltage is also the same, the more volts there are in a tool, the greater the power it can generate. To obtain sufficient voltage also means plugging in the power supply, but the discovery of the battery changed this phenomenon. Battery powered tools were early used on the moon in the 1960s. Apollo astronauts needed a small handheld electric drill to drill into the lunar surface to collect soil samples, so engineers designed a special electric tool battery pack. From then on, wireless drills emerged, and this special invention was first applied to the handheld wireless vacuum cleaner launched in 1979. Afterwards, it triggered a reform of household electric tools.

The power tools we understand and use rely on human physical energy, electricity, gasoline, and compressed air to operate, but the tools used by professionals are more powerful. In some car racing events, we often see racing repairmen using pneumatic wrenches to remove tires, as there are time constraints in the event, and they have to race against the clock to save time. The maintenance personnel only need 12 seconds to remove the nuts of the four tires, as this type of torpedo wrench can reach 25000 revolutions per minute. Its power comes from compressed air, compared to a standard pneumatic wrench with 2000 revolutions per minute. The speed of the thunder gun is 12.5 times that of them, and at this speed, the nut for dismantling the tire can be removed within 0.2 seconds. If a standard pneumatic wrench is used. Instead of changing the tire like a thunder gun, 12 seconds would turn into three minutes.

In the 19th century, there was a legendary story in which the protagonist was John Henry, a railway worker who was a strong worker at the time. His job was to drive iron nails into the tracks, and no one could match him. Later, a power tool was born, and the appearance of the air hammer made people no longer need to use brute force to drive nails. The worker fearlessly challenged the air hammer, and the human-machine battle began. Who can beat faster? The result was that human Henry won. But due to excessive physical exhaustion, he soon died. Of course, this is just a legend. In today's era, even commonly used hammers and nails cannot escape the elimination of human progress.

The emergence of a new type of electric tool nail gun, which has a speed at least ten times that of a hammer and can shoot 100 nails per minute, far exceeding the efficiency of human labor. There is also our common electric saw, which uses a two-stroke starting engine. Although it is small in size, it has a powerful engine that can drive equipment such as lawn mowers and motorcycles. When using an electric saw, the operator only needs to pull on the rope to start the starter, which drives the steel teeth on the saw chain to cut wood. The emergence of these electric tools has revolutionized the construction industry.

Of course, in addition to being used for production and manufacturing work, electric tools can also be used to save lives. Electric tools can also achieve surgical precision. In the past, surgeons have shifted from undergoing major resection surgery to minimally invasive surgery, and in order to achieve this, doctors need technical support. However, technology often means the need for power tools. We all know that surgeons will use surgical blades to make incisions when performing surgery. The problem is that such incisions will bleed. Now there is a power tool for surgery. The needle end will be heated, and it can cut and coagulate the wound with high temperature like a scalpel. Coagulation means stopping bleeding, which is very important for surgeons. It is driven by humans to turn materials into endless high-tech equipment, injecting real power into power tools.
