Description

Technical Field

[0001] The utility model relates to the technical field of drawing tools, in particular to an automatic drawing device. Background Art

[0002] When it is necessary to draw engineering drawings such as machinery and architecture manually, a drawing board is often used. Ordinary drawing boards have a simple structure, and most of them are wooden cuboids. When using it, draftsmen need to first use tape to fix the drawing paper that matches the drawing board on it, and then remove the drawing paper after drawing the relevant drawings. From the user's perspective, this drawing process is time-consuming and laborious. On the one hand, drawing drawings of different sizes require drawing boards of different sizes, which greatly reduces the utilization efficiency of the drawing board, and traditional drawing boards are relatively bulky, and there are certain difficulties in carrying and transporting them; on the other hand, the traditional drawing process not only requires draftsmen to spend a lot of time, but also has low drawing accuracy, which is difficult to meet relevant engineering requirements.
