  • About Product:Measuring method editing the tape head is loose, so that we can measure the size. There are two measuring methods when measuring the size of the tape. One is hanging on an object, and the other is pushing it to the object. The difference between the two methods is the thickness of the iron sheet on the head of the tape measure. The purpose of the tape head looseness is to compensate the iron sheet of the tape head when it is on the object.

The "inner core" of the tape measure has a small piece of steel inside, which works almost like a spring. You can also think like this, that is, the small steel wire on the cap gun trigger, which is used to "strike" the bullet. When it is pulled out, it is bent by force, after loosening, the external force (refers to the force pulled by hand, while the friction force is small, which is less than the elastic force of small steel wire) disappears, so it springs back automatically. However, there is a folded part at the front of the tape measure, which works at this time, making the tape measure stuck outside so that it will not be completely pinch in. At the beginning, he was loose. After pulling it out, he became tight. After letting it go, it should have a recovery process, so it will automatically bounce back. That is, he was loose at the beginning, and it was tight when he pulled it. There was an elastic force between them. If he loosened it, he would bounce back naturally.
