Problems solved by technology
[0002] A projector is an optical instrument that uses optical components to enlarge the outline of a workpiece and project it onto a video screen. Projectors are currently widely used in homes, offices, schools and entertainment venues. According to different working methods, there are CRT, LCD , DLP and other different types; the existing projectors are basically placed on the rack, and the rack is fixed on the top of the wall for use; but these are not convenient to carry, and it is troublesome to install. It is also inconvenient to adjust, and sometimes it is necessary for personnel to adjust the bracket with the help of a high bench, which is likely to cause safety accidents
