Problems solved by technology

[0003] In the past, in school multimedia classrooms, projectors were installed. The projectors are generally installed on the top of the wall. A controllable telescopic rod is installed above the projector. The telescopic rod is fixedly connected to the wall. Install the curtain on the wall, the installation position of the curtain needs to be determined according to the position of the projector, but often due to the deviation of the installation, the image projected by the projector on the curtain will be biased to one side of the curtain, and the up and down directions can be adjusted by telescopic rod adjustment, but the left and right directions of the projector cannot be adjusted, resulting in uncoordinated left and right directions of the resulting image, or distorting the image, thus affecting the quality of teaching
