After teaching, the second driving motor can be started to drive the driving rod and the second bevel gear to rotate, and the second bevel gear can be used to drive the round block and the storage rack to rotate, so that the card on the other side of the storage rack is rotated to the front, without the need for personnel to manually replace the card. The third driving motor can be started to drive the auxiliary rotating rod and the notch gear to rotate. Since the protruding part of the notch gear is not in the right direction, the notch gear gradually drives the pulling block and the storage rack to move upward, so that the storage rack is separated from the round block, and the user does not need to manually rotate and replace the card. At the same time, the storage rack can be moved upward in batches, so that the storage rack does not need to rotate. It can be flexibly adjusted whether the card is rotated and replaced, thereby improving the student's memory ability. BRIEF DESCRIPTION OF THE DRAWINGS
