Abstract

The invention relates to a combined measuring tool. The combined measuring tool comprises a first ruler body and a second ruler body, wherein the first ruler body and the second ruler body are in sliding connection. A fixed measuring jaw with a lower end of adjustable lengths is arranged at the left end of the first ruler body. A first sliding measuring jaw is arranged at the right side of the fixed measuring jaw. The first sliding measuring jaw is in sliding connection with the first ruler body. A measuring head is arranged at the lower end of the fixed measuring jaw. A dial indicator is arranged at the lower end of the first sliding measuring jaw. The measuring head and the dial indicator are in the same straight line. A second sliding measuring jaw with a lower end of adjustable lengthsis slidably connected with the second ruler body. The fixed measuring jaw and the second sliding measuring jaw are provided with a fixing plate capable of sliding in lateral direction. The side wallof the fixed measuring jaw, the first sliding measuring jaw and the second sliding measuring jaw are provided with a protective layer. The combined measuring tool solves the problems of limited measurement length and low accuracy of the vernier caliper.

Description

technical field [0001] The invention relates to a measuring tool, in particular to a combined measuring tool. Background technique [0002] Measuring tool is the abbreviation of physical measuring tool, which is an instrument with a fixed shape when used to reproduce or provide one or more known quantities of a given quantity. The most commonly used measuring tool is the vernier caliper. [0003] The vernier caliper is a measuring tool for measuring length, inner and outer diameters, and depth. The vernier caliper is composed of two parts, the main ruler and the sliding vernier attached to the main ruler. The main ruler is generally in millimeters, and the vernier has 10, 20 or 50 divisions. According to the different divisions, the vernier calipers can be divided into ten-degree vernier calipers, twenty-degree vernier calipers, and fifty-degree vernier calipers. The vernier is 9mm for 10 graduations, 19mm for 20 graduations, and 49mm for 50 graduations. The main scale a...
