The invention provides a combined drawing tool. The combined drawing tool comprises a disc structure and a support structure. The disc structure comprises a connecting disc, a disc cap, a cap pin assembly and an elastic assembly. The support structure comprises a first support and a clamping structure, wherein the extending side of the disc structure is connected with the first support, and the clamping structure is clamped inside the support structure and is in sliding connection with the support structure. A steel needle is arranged inside the disc structure and serves as the circle center of a compass, one end of the disc structure is vertically and rotatably connected with the first support through a shaft wheel, a sliding clamping structure is arranged inside the first support, a pen is inserted into the clamping structure, a user can use the pen to draw a circle by fixing the circle center and rotating the pen, and therefore the combined drawing tool can serve as the compass. An auxiliary ruler is arranged on the side face of the first support, the user can use the auxiliary ruler to draw a straight line with the certain length, and therefore the combined drawing tool can serve as a straight ruler. The combined drawing tool which is multifunctional and convenient to use is provided, the complex steps in the drawing process can be simplified, the combined drawing tool is convenient carry, and the comprehensive combined functions can be achieved.
Description
technical field [0001] The invention belongs to the field of drawing tools, and in particular relates to a combination tool of a disk, a ruler and a protractor for students to measure and draw. Background technique [0002] Among the common drawing tools in college students’ classrooms, two triangular plates, 45-degree and 60-degree triangular plates, as well as protractors and compasses are needed. The four tools work together to draw fixed-length lines, polygons, circles, and arcs. The above-mentioned tools are relatively common, relatively easy to obtain, and have the advantages of relatively accurate measurement results, but at the same time, they have the following disadvantages: cumbersome operation, inconvenient portability, and the function of each tool is too single. Contents of the invention [0003] The purpose of the present invention is to provide a multifunctional and convenient combined drawing tool. [0004] The technical problem to be solved by the prese...
