Abstract
Description
technical field
[0001] The invention relates to a plotter, in particular to an integrated plotter used in classrooms of various engineering graphics courses. Background technique
[0002] In the classrooms of various engineering graphics courses in engineering colleges and universities, the drawing of various graphics such as straight lines, circles, arcs, angles, and ellipses is often involved. When teaching, teachers need to carry a variety of drawing teaching aids such as rulers, set squares, anglers, and compasses. They need to switch teaching aids or even combine multiple props from time to time. The operation is cumbersome and inconvenient to carry, which brings a lot of inconvenience to classroom teaching.
