Problems solved by technology

[0002] Ordinary rulers only have the function of measuring length, and do not have the function of measuring angles and drawing arcs.
For some objects, such as carpentry, you often need to use measuring and drawing tools such as rulers, protractors, and compasses. When you need to use the functions of length measurement, angle measurement, and arc drawing, carrying multiple tools will lead to measurement and drawing. It is very inconvenient when working with wires, and one of the tools is easy to lose

Abstract

The invention discloses a multifunctional measuring and line drawing ruler which comprises a ruler main body, a movable ruler, an installation structure, an angle scale, a first datum line and a second datum line. The movable ruler is rotationally arranged on the ruler body, the installation structure is arranged on the movable ruler and used for installing a line drawing pen, the angle scale is arranged on the ruler main body, the circle center of the angle scale coincides with the rotation center of the movable ruler, the first datum line is arranged on the ruler main body, a drawing radiusline is formed between the rotation center of the movable ruler and the center of the line drawing pen, the drawing radius line can coincide with the first datum line, the second datum line is arranged on the ruler main body, the movable ruler is provided with an angle measuring line which can coincide with the second datum line, and the angle measuring line rotates along with the movable ruler toform an angle measuring mechanism with the second reference line. According to the measuring and line drawing ruler, the movable ruler which is rotatably arranged on the ruler main body is matched with the angle scale to carry out angle measurement, the line drawing pen is arranged on the movable ruler, a circular arc line can be drawn by rotating the movable ruler, and therefore the functions ofangle measurement and circular arc line drawing can be added through a simple structure.

Description

technical field [0001] The invention relates to the technical field of measuring tools and line drawing tools, in particular to a multifunctional measuring line drawing ruler. Background technique [0002] Ordinary rulers only have the function of measuring length, and do not have the function of measuring angles and drawing arcs. For some objects, such as carpentry, you often need to use measuring and drawing tools such as rulers, protractors, and compasses. When you need to use the functions of length measurement, angle measurement, and arc drawing, carrying multiple tools will lead to measurement and drawing. It is very inconvenient when working with wires, and one of the tools is easy to lose. Contents of the invention [0003] In order to solve the above problems, the purpose of the present invention is to solve at least one of the technical problems in the prior art, and provide a multi-functional line measuring and drawing ruler, which can increase the functions of...
