The tape measure is a must at home, and you need to use a tape measure for daily measurements, but do you really understand all the functions of the tape measure?
1. Attentive friends may find that most of the tape measures will be marked with a number on the back. Like this tape measure marked 68 mm. This 68 mm actually refers to the size of this section of the tape measure shell. When we are measuring, if we encounter a corner, the tape measure bending simply cannot read the exact size. At this time, we only need to pull the tape measure to the end, we can read the size measured on the tape measure, plus the length of the tape measure shell 68 mm, you can get the accurate size.
2. People who regularly use a Horse weight lbs tape measure may find that the small iron sheet in front of the tape measure can be moved back and forth. The distance of movement is about one millimeter.
Many people do not understand, why manufacturers do not fix it when making it, in fact, the design of the tape measure is very scientific. When we measure the outer distance of the object, we pull the tape measure backwards, and the distance of this millimeter is the starting distance of the starting point. The measured dimensions are the most accurate. When we measure the inner dimensions of the object, the roll retracts by a millimeter. Because the iron sheet itself has a thickness of one millimeter, the retracted one millimeter just cancels out the thickness of the iron sheet. That's why small iron sheets are designed to move back and forth? The flexibility of this small iron sheet is also a very important quality requirement of the tape measure, we must carefully check the flexibility of the iron sheet and whether the workmanship is fine when purchasing the tape measure.
3. There will be a clip on the back of the roll. Many people will use this clip to clip it to the waistband of the pants, but it has another role. You can clip a pen with the help of a long tail clip, and then clip the long tail clip to the tape measure clip, when we are measuring, we can use the marker pen to mark at any time, which is very convenient.
4. There will be a hole in the hook in front of the Pi tape measure tape measure. This hole is used to hold the tape measure. When we are measuring some relatively long distances, and there is no one around to help, we only need to nail a nail at the starting point, and fix the hole in front of the roll on the iron nail, so that one can easily complete the measurement without error.
5. In addition to so many hidden small features above, the hook in front of the volume can also be used to make marks. Very convenient.
