Free of the most classic humorous jokes to grasp first-hand military intelligence.

According to Xinhua News Agency, the legend of Lu Ban's invention of the saw is almost a household name in China. However, when this reporter interviewed in the Bahrain Right Banner in Chifeng City, Inner Mongolia Autonomous Region, in the Liaohe River Basin this autumn, he found that this legend is not credible. As early as the Neolithic period, the Hongshan people living in the territory of Chifeng City, Inner Mongolia, invented the saw.

The reporter witnessed the fragment of a stone saw invented by the Hongshan people in the Neolithic period, which is about 5 centimeters long and 1 centimeter wide, and the sawtooth is clearly visible. This fragment of a stone saw was picked up by Yang Chunguang, chairman of Bahrain Stone Group Co., Ltd., at the northern foot of Mount Tenigeltu the year before last. The Hongshan culture appeared at least 7,000 years ago, and it is estimated that the appearance of stone saws was two or three thousand years earlier than the era in which Luban lived.

Yes, legend has it that his woman was scratched by the leaves of a grass when she went up the mountain, and she was inspired to invent it.

When I was in elementary school, I learned a text that said that Luban was scratched by a small grass with jagged teeth on the mountain, and later invented the saw.

Luban. The leaves were scratched, oozing blood, he picked the leaves and touched them gently, it turned out that there were sharp teeth on both sides of the leaves, and he used these dense small teeth to lightly scratch on the back of his hand, and actually cut a cut. His hand was cut by these small teeth, and he saw a large locust on a weed, and there were many small teeth lined up on the two large plate teeth, so that the leaves could be ground very quickly.

Lu Ban was inspired by these two things. He thought, if such a toothed tool could also cut through trees very quickly! So, after many experiments, he finally invented a sharp saw, which greatly improved the work efficiency.

Luban gave this newly invented tool a name called "saw".

Luban (507 BC - 444 BC), the state of Lu during the Spring and Autumn Period.

People, Ji surname, Gong Yi Shi, the word Yizhi, the name class, people are called Gong Losing.

Gong loses, class loses, honorific public losers, also known as Lu Pan or Lu Pan, commonly known as "Lu Ban". The name of Luban has actually become a symbol of the wisdom of the ancient working people.

For more than 2,400 years, people have concentrated the collective creations and inventions of the ancient working people on him. Therefore, the story about his invention and creation is actually the story of the invention and creation of the working people in ancient China.

The saw isLuban. Invention,Legend has it that when Lu Ban built a palace, he used more wood, but in ancient times, logging was far from what was needed for construction, so he was inspired by the edge of the toothed blades of thatch and created the saw.

The oldest carpentry hand saws are usually structured in the shape of a saw. By adjusting the tightness of the screws on the opposite side of the saw blade, the saw blade is straightened and easy to operate, and after continuous improvement, it is now smaller and smaller, and there are more varieties.

The story of Luban's invention of the saw.

Lu Ban needed a lot of wood after taking over the construction task of a huge palace, so Lu Ban asked his apprentices to go up the mountain to cut down trees, and the apprentices used inefficient axes to cut down, although the craftsmen worked hard every day to get up early and work at night, they couldn't cut down many trees, and the project progressed.

just can't go up, Lu Ban is very anxious when he sees that the construction period is getting closer and closer. So he decided to go up the mountain to see the trees cut down himself.

When he went up the mountain, he inadvertently grabbed a handful of wild grass on the mountain and his hand was scratched, and Lu Ban was very puzzled how a soft grass could cut his hand. So he plucked a leaf to observe, he found that there were many small teeth on both sides of the leaf, and when he touched these small teeth with his hand, they were very sharp, and Lu Ban understood that it was these small teeth that cut his hand, and then he invented the saw.

Lu Ban stumbled upon the small fine teeth on the thatch, through careful observation, serious thinking, and so on to invent the saw blade, we should carefully observe the details in life, seriously think about the principle, to draw inferences from one another, and understand it thoroughly. At the same time, there is a connection between things, and everything will have some kind of connection.

Legend has it that one day, when Luban was going up the mountain, one accidentally slipped and was cut by a kind of wild primrose. Lu Ban took a closer look, and there were many small teeth on both sides of this leaf. He thought, wouldn't it be equally sharp if the tools used to cut wood were made jagged?

Thus, the saw was invented.

Legend has it that once when Luban fell deep in the mountains to cut down trees, his hand was cut by weeds, and it was the sharp serrations on this grass that inspired him. Lu Ban made the same sharp tooth tool from the grass, which can quickly sawn trees. Luban gave this newly invented tool a name called "saw", which is the origin of the saw.

During the Spring and Autumn Period and the Warring States Period, there was a creative inventor named Lu Ban in my country. For more than 2,000 years, his name and stories about him have been passed down among the people, and later generations of woodmakers have honored him as their ancestor.

Definition of saw: A saw is a tool used to cut or cut wood or other items that need to be processed. It consists of a saw blade and a saw body made up of irregularly arranged serrations.

Broadly speaking, it refers to a tool that separates objects by using the repeated movement of multiple contact points with huge pressure arranged in a single column. Common forms (as distinguished from knives and files) include woodworking saws, disc chainsaws, band chainsaws, wire saws, etc.

2. Be good at collecting information.

3. Elevate perceptual cognition to a space of rational cognition.

4. Invention is people-oriented, in order to facilitate life and transform life, rather than pursuing luxury and nothingness.

Inventing the Legend of the Saw:

The saw used by carpenters is said to have been invented by Luban. Originally, there were no saws, and the carpenters used axes to chop wood. Once, Lu Ban was working on the mountain, and suddenly something cut his hand, and blood flowed.

When he looked for it, it turned out to be a silk thatch, and the silk thatch had many hard and sharp teeth on it, and the flesh of the human being was broken by it. Lu Ban was inspired by this: if you make long strips with teeth from metal, wouldn't you be able to saw the wood?

So, Luban invented and manufactured a metal saw. (According to archaeological materials, China's primitive society had a toothed mussel sickle, and the Shang Dynasty already had a small copper saw.) )
