Description

Technical Field

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

[0002] As we all know, learning mathematics and physics requires drawing; the commonly used drawing tools in mathematics are triangle rulers, protractors and compasses; when learning physics from junior high school, there are no special drawing boards to use when encountering light path diagrams and circuit diagrams, and physical diagrams are different from geometric diagrams. Physical diagrams have specific meanings, that is, meanings related to physics, and they must be connected with physics when drawing. In particular, the physics drawing board plays a positive role for students who are just beginning to learn physics, from not being able to draw to being familiar with drawing.

[0003] The existing geometry model rulers are relatively large in size. Although they have many diamond and ellipse patterns, it seems that one board can draw multiple pictures. However, when drawing on books, it is difficult to draw in the designated position due to its large size. In particular, there are currently no professional physical drawing boards on the market, which is not conducive to cultivating students' drawing skills. Utility Model Content
