Originally published as can you really use a tape measure? ☞ This is article 8321 posted by Metalworking (mw1950pub) Guided reading Tape measure, a necessary measuring tool for home and work. Gold fans must be familiar with it, but "familiarity is not equal to true knowledge", for example, have you ever wondered why the hook of a tape measure shakes back and forth? What is the number on the ruler shell? The mystery of the tape measure Tape measure, I believe everyone is familiar with it, but 99% of people do not know about the practical functions of tape measure. 1. The ruler hook will shake back and forth, many people think that it is not done well, shaking will lead to inaccurate measurement, but the fact is that the ruler hook shaking back and forth is not not done well, but for more accurate measurement. When you need to measure the outside diameter,bra measuring tape, you need to pull the tape back so that the measurement is accurate. 2. The function of the magnet on the ruler hook is that when measuring a long distance, if there is an iron plate in front of it, it is just attracted by the magnet, and there is no need for a person to hold the ruler hook, which is very practical; the function of the sawtooth on the ruler hook is that when measuring the length of wood,custom tailor tape, there is no marking tool, and you can use the sawtooth to mark the mark.

What is the corner? At this time, the ruler shell is used. You need to place the tape on the same plane, with the housing of the tape stuck at the bottom, and then read the length on the tape, plus the 3-foot length of the tape itself, and you get the exact length of this distance. Let me share another video with you. After a simple improvement by a foreign brother, the tape measure has a wonderful use. I believe many gold fans who have practiced metalworking also know this trick: The video lasts 4 minutes and 59 seconds, mini tape measure ,personalised tailor tape, and WiFi is recommended to watch it. The principle of a tape measure China is a big producer of tape measures, which are produced in Yuyao, Zhejiang and Shangqiu, Henan. The quality of Yuyao factories is better, and of course the price is more expensive. Other places also have production, the more famous Ningbo Great Wall Seiko, I believe everyone has heard or used. Now that we've talked about it, let's take a closer look at the tape measure. The construction of a tape measure The tape measure is mainly composed of a shell, a tape strip, a brake, a tape hook, a lifting belt, a tape spring, an anti-falling protective sleeve and a label. The specific functions are as follows: 1. Shell: ABS new plastic, with glossy texture on the surface; resistant to falling, wear-resistant and not easy to deform. 2. Ruler: 50 # Grade I strip steel with a thickness of 10 wires (0.10 mm) shall be used. 3. Braking: With upper, side and bottom three-dimensional braking, the hand control feeling is stronger. 4. Ruler hook: The rivet ruler hook structure is not easy to deform and ensures more accurate measurement. 5. Lifting belt: two types of rubber and nylon; high-grade and high-quality; strong and durable, with good hand feeling. 6. Ruler spring: generally made of 50 # carbon steel and 65 # manganese, with strong toughness and high accuracy. 7. Anti-fall protective cover: high-quality plastic to prevent falling and collision damage and enhance durability. 8. Labeling: Labeling production can be carried out according to customer requirements. How a Tape Measure Work After the tape is pulled out, the fixed tape can be rolled up because there is a spring inside the tape. When the tape is pulled out to measure the length, the length of the ruler and the spring is actually lengthened. Once the measurement is completed, the spring inside the tape will automatically contract, and the ruler will also contract under the action of the spring force, so the tape will be rolled up.
