Problems solved by technology

[0002] Because multimedia has the characteristics of graphics, text, sound and even moving images, it has many characteristics and functions that are especially valuable to the education and teaching process. These characteristics and functions are not available or not fully available in other media. Yes, projection equipment is an important part of multimedia equipment. It can display pictures and texts in the multimedia teaching process, so that multimedia can better serve teaching. The patent application publication number is CN201711470980.1. Projection equipment for multimedia teaching. The existing projection equipment has the advantages of simple installation, convenient operation, flexible use by personnel, and power saving. It can meet the functional requirements of multimedia teaching. However, for the existing projection equipment On the one hand, it is not easy to install and disassemble. In some areas, due to the limited multimedia equipment, multimedia classrooms need to be used in turn to give lectures, which takes up a lot of time for students to change classrooms and seats. It is inconvenient to use and is not conducive to ensuring effective class time. On the other hand, the inability to freely adjust the angle of projection is not conducive to ensuring the use of projection equipment in different locations. On the other hand, when the installation of fixed equipment fails, it cannot effectively avoid the fall of the projection equipment, which is not conducive to protecting the projection equipment. device security
