Description

technical field [0001] The invention is an easy-to-use multimedia interactive teaching device, which belongs to the technical field of multimedia interactive teaching devices. Background technique [0002] Projectors are used to provide visual information for the crowd. With the development of electronic technology, projectors are becoming smaller and more portable. Because the projector lens is fragile, it is easy to be damaged when carrying it. A corresponding protective structure is needed to protect it. This lens, in addition, when the projector projects visual information, it is necessary to adjust the angle of projection according to the actual situation of the playing site, and generally after the projector is set up on the projector bracket, it is difficult to adjust the angle of the projector lens as needed. The projection angle should be fine-tuned appropriately, and the projector must also be placed on a level table. [0003] However, the existing technology is n...
