A rotating base is fixedly installed in the middle of the upper surface of the base. A supporting column is vertically arranged in the middle of the top end of the rotating base. The upper portion of the supporting column is sleeved with a telescopic rod matched with the supporting column. A main display board is hinged to the top end of the telescopic rod. According to the invention, magnetic sheet clampinggrooves are arranged above the main display board. Scraps written with fragmentary knowledge points can be adhered to the main display board through the magnetic sheet clamping grooves. The classroomteaching efficiency is improved. Students can observe samples conveniently through cooperation of the illuminating lamp, the display box and the mechanical clamp. The teaching process is vivid and visual. A recording device can record teaching content of teachers. Therefore, the leakage checking, the vacancy filling and the cyclic utilization are facilitated.
