Abstract

The invention discloses a vernier caliper. The range of the vernier caliper is adjustable, so that the use cost of the vernier caliper is reduced, the measurement efficiency and measurement accuracy are improved, and the vernier caliper is convenient to carry. The vernier caliper comprises a fixed main scale, a movable main scale and a vernier, wherein the movable main scale can be contained at the rear side of the fixed main scale, and the head of the movable main scale can be butted with the tail of the fixed main scale; and the vernier is arranged on the fixed main scale in a sliding manner and can be mounted with the movable main scale in a sliding manner when the fixed main scale is butted with the movable main scale.

Description

technical field [0001] The invention relates to the technical field of measuring tools, in particular to a vernier caliper. Background technique [0002] The vernier caliper is a high-precision 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. The main scale is generally in millimeters, and the vernier has 10, 20 or 50 divisions. According to the divisions, the vernier calipers can be divided into ten-degree vernier calipers, twenty-degree vernier calipers, and fifty-degree vernier calipers. The main scale and vernier of the vernier caliper have two sets of movable claws, which are the inner measuring claw and the outer measuring claw. The inner measuring claw is usually used to measure the inner diameter, and the outer measuring claw is usually used to measure the length and outer diameter. The depth gauge is connected with the vernier to measure the depth of th...
