Español4 ingenious designs of steel tape measure and how to use it
Steel tape is a common measuring tool. When using steel tape, you will find that many of its designs are difficult to understand. In fact, every seemingly strange design on the steel tape measure is not tasteless, but we don't understand their real use. Today we will take a look at 4 ingenious designs of steel tape measures and how to use them.
First, if you have carefully observed the steel tape measure, you will remember that there is a hole in the hook of the steel tape measure.
So what exactly is it for? The picture below will give you an instant understanding. That's right, it can be stuck on the nail in this way, and then you don't need another hand or another person to help you fix the steel tape measure. Second, the edge of the hook of the steel tape measure 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.
Third, the position of the foremost end of the steel tape can be moved, and the length of the first grid is generally shorter than the length of the second grid.
Many people think that the design of this activity will affect the accuracy of the steel tape measure, but in fact, the flexible hook of the steel tape measure is a very important quality requirement of the steel tape measure.
In fact, when using a steel tape to measure the outer diameter of an object, you need to pull the steel tape back so that the measurement result is accurate. If you measure the inner diameter of an object, the steel tape measure hook itself has a thickness, and then you need to retract this movable distance. This is why the front end of the steel tape is designed to be flexible.
Fourth, we often see numbers on the steel tape measure shell, but we don’t know its purpose.
For example, this steel tape is marked with the number 65mm, so what exactly is it used for? In fact, it represents the length of the outer casing of the steel tape measure.
