Abstract

The invention relates to the technical field of drawing devices for mathematics learning, and discloses an all-purpose drawing device used for mathematics learning. The problems that current mathematics drawing tools are single in function, are not convenient to use or carry and cannot be effectively combined for use are solved. The all-purpose drawing device comprises a right-angle triangle ruler. The right-angle long side of the right-angle triangle ruler is movably connected with a measurement long ruler. First measurement graduated scales are engraved on the right-angle short side on the top of the right-angle triangle ruler and the tilted side correspondingly. A straight line groove is formed in one side of the right-angle long side on the top of the right-angle triangle ruler. A second measurement graduated scale is engraved on one side of the top of the measurement long ruler. The all-purpose drawing device used for mathematics learning is more diversified in function and can meet different drawing requirements; meanwhile, the all-purpose drawing device is of a spliced integrated structure, and therefore the all-purpose drawing device is convenient to detach, use and carry;and the all-purpose drawing device can be effectively combined to be used, the number of drawing tools is effectively decreased, and the all-purpose drawing device is more practical.

Description

technical field [0001] The invention belongs to the technical field of drawing devices for mathematics learning, in particular to a universal drawing device for learning mathematics. Background technique [0002] Mathematics is a discipline that studies concepts such as quantity, structure, change, space and information. Observation of the shape and motion of objects; Mathematics has become part of the education in many countries and regions, and it is applied in different fields, including science, engineering, medicine, economics and finance. [0003] In the process of learning mathematics, various graphics will be drawn to assist learning, but the current drawing tools are of various types, and most of the tools only have one function for drawing pictures, so it is necessary to carry various drawing tools during the learning process , it is very inconvenient to use and carry, and at the same time, various drawing tools cannot be used in effective combinations, thereby la...
