Problems solved by technology
[0003] When the teacher is giving a lecture, he needs to prepare the lesson before. When he arrives in the classroom, he also needs to bring some books to help the lecture. The shape and size of the school bag are relatively fixed, and it is relatively large and inconvenient to carry. The books carried during teaching are not just a book. The traditional school bag can hold books but not drawing tools. If the book gets wet, if you bring it with the rest of the books in a school bag, it will be easier to get the rest of the books wet. Traditional drawing tools are usually scattered, and the compass and ruler are separate. If you want to draw Drawing a straight line and drawing a circle requires more tools to be carried, so in order to solve these problems, it is necessary to design a teaching aid carrying device
