The tape measure is a commonly used length measuring tool in daily life. Because the tape measure is equipped with a spring, when the tape measure is pulled out to measure the length, the length of the ruler and the spring is actually stretched. Once the measurement is completed, the spring inside the tape measure will automatically shrink.
