The tape measure, I believe everyone is familiar with it, but many people do not know these practical functions of the tape measure.

1. The ruler hook will sway back and forth. Many people think that it is not done well, and the shaking will lead to inaccurate measurements. The fact is that the ruler hook is not not well done, but it is to make the measurement more accurate. When encountering this required outer diameter, you need to pull the tape measure back so that the measurement is accurate.

2. The function of the magnet on the ruler hook is that when a relatively long distance is measured, if there is an iron plate in front of it that is just attracted by the magnet, there is no need for another person to hold the ruler hook, which is very practical; the sawtooth on the ruler hook is very practical. The function is that there is no marking tool when measuring the length of the wood, and you can use the sawtooth to mark the mark.

3. The numbers on the ruler shell are also very practical. Have you ever encountered a corner when testing, and it is not easy to read when the ruler is folded. How much is the corner? At this time, the ruler shell is used. You need to place the tape measure on the same plane, with the outer casing of the tape measure stuck at the very bottom, then read the length on the tape measure, add the 3 feet of the tape measure itself, and you will get the exact length of this distance.
