[0002] Compulsory education is the education that all school-age children and teenagers must receive, and it is a public welfare undertaking that the country must guarantee. The quality of compulsory education is related to the healthy growth of hundreds of millions of children, the development of the country, and the future of the nation. This is a system of compulsory education for school-age children and teenagers for a certain period of time in accordance with the provisions of the law. Compulsory education is also called compulsory education and free compulsory education. Compulsory education has the basic characteristics of compulsory, free, universal and secular , in the stage of compulsory education, a kind of teaching demonstration equipment commonly used by teaching staff is the blackboard. With the continuous development of science and technology and the continuous provision of education funds, the current blackboards mostly use blackboards and computer screens for multimedia teaching. The equipment divides the blackboard into multiple plates and installs them in a rectangular frame. The blackboard slides through the chute on the rectangular frame, and the computer screen is placed in the center of the rectangular frame. The device demonstrates teaching to students through the computer screen At the same time, the teaching staff can also write part of the teaching content on the blackboard on the side, which is more flexible and convenient than the traditional projection screen. However, in the actual use process, since the rectangular frame is sealed Due to the structure, the chalk dust is easy to accumulate in the rectangular frame, hidden in the back of the rectangular frame, making it very inconvenient to clean up the dust, and because the computer screen is in the rectangular frame, when students observe, the edges of the computer screen The content of the position is easily blocked, so that students cannot observe it, and when the blackboard is in use, reflections often occur, so that students on the left and right sides cannot see the content, and the structure of the blackboard can be adjusted to the left and right sides to make it easy to use inconvenient
