Abstract
The utility model relates to a ruler which comprises a straight scale; two ends of a long side of the straight scale, marked with scale marks, are respectively provided with a convex column; and the surface of the straight scale is sheathed and connected with a sliding sleeve along the direction of the long side. The ruler has the advantages of being reasonable in structure, convenient, practical, simple in operation and the like.
Description
Technical field
The utility model relates to a kind of instruments of labour, especially a kind of survey tool.
Background technology
As everyone knows, ruler is one of measurement drawing instrument commonly used in people's study and work.But present ruler structure is too dull, all adopts strip chi bar structure, though the function of measuring and drawing can be provided, nib and chi face graduation mark have certain distance when draw line segments, are easy to cause error, influence drafting accuracy.
Summary of the invention
The purpose of the utility model provides a kind of easy to use, rational in infrastructure and can improve the ruler of drafting accuracy.
The utility model mainly comprises ruler, and the two ends, long limit that indicate graduation mark at ruler are respectively equipped with projection; On the ruler surface along long side direction socket sliding sleeve.
During use, the user can normally use ruler to measure length.When drawing straight line; The user at first confirms line segment length, then at ruler surface slip sliding sleeve, makes that length equals line segment length to be painted between sliding sleeve and the zero graduation; Grow limit setting-out to sliding sleeve one side along ruler from the ruler zero graduation with nib then; Nib arrives the sliding sleeve place to be stopped, because sliding sleeve and nib distance are nearer, therefore can improve precision.The projection of ruler both sides can provide protective effect, avoids the sliding sleeve landing.
Compared with present technology, the beneficial effect of the utility model is: rational in infrastructure, convenient and practical, simple to operate, but accurate measuring length and drafting straight line.
Description of drawingsFig. 1 is the stereochemical structure sketch of the utility model.
The specific embodimentIn the stereochemical structure sketch of the utility model shown in Figure 1, mainly comprise ruler 1, the two ends, long limit that indicate graduation mark at ruler are respectively equipped with projection 2; On the ruler surface along long side direction socket sliding sleeve 3.
Claims (1)
1. a ruler mainly comprises ruler (1), it is characterized in that: the two ends, long limit that indicate graduation mark at ruler (1) are respectively equipped with projection (2); Surperficial at ruler (1) along long side direction socket sliding sleeve (3).
