[0002] Vernier caliper is a measuring tool for measuring length, inner and outer diameters, and depth. It is mainly composed of a main scale and a sliding vernier attached to the main scale. From the back, the vernier is a whole. The depth gauge is connected to the vernier scale, which can measure the depth of the groove and the barrel. There are two pairs of movable jaws on the main scale and vernier of the caliper, namely the inner measuring jaw and the outer measuring jaw. The inner measuring jaw is usually used to measure the inner diameter, and the outer measuring jaw is usually used to measure the length and outer diameter. The vernier caliper has the characteristics of simple structure, easy use, medium accuracy and large measurement range.

Repeated measurements are required to find the maximum measurement value. The efficiency and accuracy are low, and the usage scenarios are limited. Utility Model Content
