Abstract

The invention discloses a vernier caliper. The vernier caliper comprises a movable clamping jaw and a caliper body provided with a fixed clamping jaw, wherein the fixed clamping jaw comprises a rotary base, a rotary rod and an idler wheel, a through hole is formed in the caliper body in the thickness direction, the rotary base is connected with the caliper body in a rotary mode through the through hole, the top of the rotary rod is cylindrical, the rotary rod is connected with the rotary base in a rotary mode, the rotary rod can rotate along the axis of the cylindrical portion on the top of the rotary rod, a rotary shaft is arranged in the center of the idler wheel, and the idler wheel is connected with the rotary rod in a rotary mode through the rotary shaft. According to the vernier caliper, due to the fact that the rotatable idler wheel type measuring jaw is arranged, the movable clamping jaw can conveniently move along with the appearance of a workpiece to be measured in the process of measurement, and accuracy and convenience of measurement are improved.

Description

technical field [0001] The invention relates to a vernier caliper and belongs to the field of measuring instruments. Background technique [0002] The jaws of the traditional vernier caliper are fixed, and direct and accurate measurement cannot be achieved in some special environments. Contents of the invention [0003] In order to achieve the above object, the present invention adopts the following technical solutions: the present invention realizes the measurement of the caliber of complex wall objects and the size of other complex situations by setting a freely rotatable roller on the fixed claw. [0004] The specific plan is as follows: [0005] A vernier caliper, comprising movable claws and a bar body on which fixed claws are installed, and the fixed claws include a rotating base, a rotating rod and a roller; [0006] The thickness direction of the ruler body is provided with a through hole, the rotating base is connected to the ruler body through the through hole,...
