Technical Field

The invention relates to a drawing tool, in particular to a mathematical plotter.

Background

Most of the plane geometry drawing can only use a ruler, a compass and the like, and the ruler and the compass can be used for drawing various figures, but some figures such as curves can not be drawn. Some problems look as simple as they are, but it is difficult to actually make them, and there are tools for drawing regular curves by gears in the prior art, but one size of gear can only draw a curve of one shape, and different curves can be drawn by providing holes at different positions on one gear, but the number of curves that can be drawn is limited, which requires gears of different sizes, and thus, there is room for improvement.
