[0002] The tourism major is to cultivate first-line service and management professionals who adapt to the needs of tourism enterprises and institutions in the new situation. They have good ideological and moral qualities and comprehensive qualities, and have strong comprehensive professional abilities and development foundations. For teaching, the multimedia teaching equipment in the prior art generally adopts projection multimedia. After installing the projector on the corresponding position on the projection screen, since the height of the screen is different, it is necessary to manually adjust the projection angle of the projector. It is inconvenient to adjust the projection angle of the projector when the projector is aligned with the screen, and because the projector slides down by its own gravity after a long time, the projection angle deviates and affects its use effect. It is more stable than those fixed on the wall, but the height is inconvenient to adjust, resulting in people blocking and affecting projection consumption

However, in the teaching of tourism majors, in order to allow students to learn more intuitively, multimedia devices such as projectors or notebook computers are used. Using notebook computers is convenient for teachers to carry and move them for students to watch, but notebook computers do not have projection equipment. , causing the teacher to be unable to teach, and the existing teaching projectors are generally fixed on the top of the classroom wall, but the connection method of the projector is not stable enough, and it is prone to accidental drop, which not only causes damage to the projector, but also damages the students. Teacher safety poses a hidden danger
