Description

Combined vernier length measuring structure Technical field: the utility model relates to the technical field of measuring tools, in particular to a combined vernier length measuring structure. The background technology is as follows: Students learn tools are numerous. For a student population, multiple measurement tools need to be frequently contacted during daily learning. For example, the students can learn to use vernier calipers in the junior middle school stage, the learning stage is only several weeks, partial poor schools cannot purchase teaching aids in batches, one-hand learning cannot be achieved, the students can take away the learning, the students can only conduct grouping and alternate practice, even only see the learning degree, the learning efficiency of the students is reduced, the students can purchase the vernier calipers independently for learning, the purchasing cost is greatly increased, the service period is short, the tool is inconvenient to arrange, store and carry in the process, unnecessary trouble and cost burden are brought to the students, the learning efficiency and the teaching level are reduced, and meanwhile, the conventional vernier calipers 50 are difficult in indexing degree due to the fact that a plurality of scale marks are aligned. In conclusion, the fact that students learn that the vernier caliper lacks practical operation conditions is the biggest problem in learning. The utility model comprises the following steps: The present utility model is directed to a combined vernier length measuring structure, which solves the above-mentioned problems in the prior art. The utility model is implemented by the following technical scheme: A combined vernier length measuring structure comprises an independent platy first structure body and a second structure body, wherein the independent platy first structure body and the second structure body are in edge joint, the first structure body comprises at least four straight edges and are connected end to end, at least one concave angle is formed by two edges, a length scale mark is arranged on one straight edge in the horizontal direction of the concave angle, the second structure body comprises at least three straight edges and are connected end to end, at least one convex angle is arranged on the second structure body, the convex angle is formed by two straight edges, vernier scale marks are arranged on one straight edge in the horizontal direction of the convex angle, the length scale marks and the vernier scale marks are formed by a plurality of uniformly distributed scale lines, the concave angle and the convex angle are right angles, and one edge in the horizontal direction of the concave angle and one edge in the horizontal direction of the convex angle are mutually joint and mutually slide. Preferably, the concave angle and the convex angle are right angles, and the first structure body and the second structure body are independent plate-shaped structure bodies. Preferably, the first structure body comprises four straight edges and is connected end to end, the whole body is formed by integrally splicing two triangles to form four straight edges, wherein the two straight edges form a concave angle, the second structure body comprises three straight edges and is connected end to end, the whole body is a right triangle, and the two straight edges form a convex angle.
