Analysis of Wanhua Ruler Play：
1.First press the ruler with your left hand and fix it on the drawing paper.
2.Select any external gear and put it into the internal gear plate to make it mesh without disengaging and jumping teeth; hold the ballpoint pen in your right hand and insert it so that the pen is perpendicular to the paper and rotate it in a certain direction to draw a beautiful curve pattern.
3.Replace one more as needed, and draw two or more gears separately on the original drawing, or move them up and down in parallel in one direction to draw a variety of different patterns.
