EspañolThe Four Secrets of the Tape Measure
The tape measure is a very common tool in life, but we often find that many of its designs are difficult to understand when we use the tape measure. In fact, every odd-looking design on the tape measure isn't rubbish, it's just that we don't understand what they're really for.
一、if you've looked closely at the tape measure, you'll remember that there is a hole in the hook of the tape measure.
You can stick to the nails this way, and then you don't have to have the other hand, or another person, to hold the tape measure for you.
二、 the edge of the tape measure hook is not flat, but toothed.
Its use is when you need to draw a line at the place to be measured, but you don't have a pen in your hand. Press and rub it on the position where you need to draw a line for a few times, and you can draw a line to help you identify it. .
三、the position at the front end of the tape measure can be moved, and generally the length of the first grid is shorter than the length of the second grid. Many people think that the design of this activity will affect the accuracy of the tape measure, but in fact the tape measure Hook flexibility 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 back, 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 you need to retract this movable distance back. This is why the front end of the tape measure is designed to be flexible.
四、 we often see numbers marked on the tape measure shell, but we don’t know its purpose. For example, this tape measure is marked with the number 65mm, so what is it used for? It actually represents the length of the tape measure housing.
