Tape measure is a very common tool in life, but we often find that many of its designs are difficult to understand when using a tape measure. In fact, every seemingly strange design on the tape measure is not tasteless, but we don’t Just understand their real usefulness.
Below we are going to reveal the 4 secrets of the tape measure, they will definitely make you re-understand how ingenious the design of this common tool is.
If you have observed the tape measure carefully, you will remember that there is a hole in the hook of the tape measure.
So what exactly is it for? It can be stuck on the nail in this way, and then there is no need for another hand or another person to fix the tape measure for you.
The edge of the tape measure hook is not flat, but toothed.
Its usefulness is when you need to draw a line on the measuring place and you don’t have a pen in your hand. Hold it on the place where you need to draw a line and rub it a few times, and you can draw a line to help you identify it. .
The tip of the tape measure can be moved, and generally the length of the first frame is shorter than the length of the second frame. Many people think that the design of this movement will affect the accuracy of the tape measure, but in fact the tape measure hook is flexible It is a very important quality requirement for tape measure.
In fact, when using a tape measure to measure the outer diameter of an object, you need to pull the tape measure backwards so that the measurement result is accurate. If you measure the inner diameter of an object, the tape measure hook itself has a thickness, and then you need to retract this movable distance. This is why the front end of the tape measure is designed to be flexible.
The last secret about the tape measure is the number on it. We often see that the tape measure is marked with a number, but we don’t know its purpose. For example, the tape measure is marked with the number 3, so what is it for? What about? In fact, it represents the length of the tape measure shell.
Suppose you measure the length of the window, and you cannot read the exact number at the corner. At this time, the number marked on the tape measure will play a huge role.
You need to place the tape measure on the same plane, with the tape measure's shell stuck at the bottom, and then read the length on the tape measure, plus the length of 3 feet of the tape measure itself, you will get the exact length of this distance.
