So that twisting central shaft 9 clockwise or counterclockwise, external toothing 10 rotates clockwise drafting circle；It is multiple if necessary to draw simultaneously
Concentric circles, it is only necessary to install drawing pen 15 respectively on multiple radius regulating mechanisms, radius be adjusted respectively, then according to top
Step is drawn.
If the radius of circle drawn is smaller, stabilizer blade 3 influences the drafting of circle, can remove stabilizer blade 3, by one in drawing process
Hand firm banking 1 carries out the drafting of circle；It, can be by the second ruler item 22 from the opposite side of the second sliding block 21 if fruit radius is excessive
It is inserted into, drawing pen 15 is made to be placed in outside, increase the range for drawing radius, the size for drawing center of circle radius passes through 19 He of the first ruler item
Scale on second ruler item 22 carries out plus-minus acquisition.
Different drawing pens 15 should be selected when being drawn in different materials, such as：When being drawn on paper, draw
Pen should select pencil or oil pen；When being drawn on wooden tablet, drawing pen 15 should select pencil or free ink pen；In metal
When surface is drawn, drawing pen 15 should select pencil or watercolor pencil；When being drawn on smooth hard surface, drawing pen 15 should
Select watercolor pencil.
