Civilian scissors, as the name suggests, are scissors commonly used by the general public, while industrial scissors are mainly used in the field of industrial construction. There are obvious differences between the two, which will be introduced in detail today:

The difference between civilian scissors and industrial scissors-YangjiangScissorsFactory
  1. In terms of material, civilian scissors are generally made of stainless steel, while industrial scissors are generally made of manganese steel because this material has good wear resistance and high hardness, and is not easily damaged or bent.

Another difference between civilian scissors and industrial scissors is the design of the handle. Civilian scissors only need to be simple and convenient to use, and if necessary, efforts can be made to design the structural shape. Industrial scissors, on the other hand, need to be sleeved on the outside because the friction force of industrial scissors is relatively high. Therefore, we need to fully consider this in the design process.

The use of scissors is based on the principle of labor-saving in physics, also known as the lever principle, which allows for the use of smaller forces to accomplish tasks that require greater force.

The ancient Greek scientist Archimedes had a famous saying that has been passed down through the ages: "If you give me a fulcrum, I can move the earth!" This sentence is not only an inspiring admonition, but also has strict scientific basis. The lever principle in scissors is the same as this.

By the way, there have been records of leverage in the history of our country. The Mohist school of the Warring States period once summarized the laws in this regard, and there are two articles in the "Mojing" specifically recording the principle of leverage. These two statements are very comprehensive about the balance of leverage. There are equal arms and unequal arms inside; There are ways to deflect it by changing the weight at both ends, as well as by changing the length of the two arms.
