The working principle of the thousand meters

The working principle of the micrometer is to move the tiny straight line of the measuring rod caused by the measured dimensions, and to enlarge the gear drive, to turn the meter on the dial to read the size of the measured size.

The structure of the micrometer is simpler, the transmission mechanism is the gear system, the outer outline size is small, the weight is light, the drive mechanism is small, the transmission ratio is big, can use the circumference scale, and has the larger measuring range, not only can make the comparison measurement, but also can make the absolute measurement.
