The utility model relates to the technical field of showing stands for teaching, and discloses a showing stand for teaching, which can be overturned and folded and comprises a function plate frame, a sliding groove is formed in the inner wall of the function plate frame, a rotating shaft is connected to the inner wall of the sliding groove in a sliding mode, and two function plates are connected to the end, away from the sliding groove, of the rotating shaft in a rotating mode. The end portions of the two function plates are fixedly connected with bosses and provided with shallow grooves respectively, and the end portions of the function plate frames are in threaded connection with bolts. According to the utility model, the two separable and symmetrically-folded function plate frames and the function plate are arranged, when in use, the folded function plate frames are unfolded to be horizontal and are pushed inwards, so that the two function plate frames are combined, and the function plate is respectively rotated to a desired surface through the rotating shaft; the two functional plates are pushed to enable the rotating shafts to slide to proper positions in the sliding grooves, the two functional plates are combined into a whole functional plate through the bosses and the shallow grooves on the side faces, and the bolts on the two sides of the functional plate frame are rotated to drive the push plates to rotate inwards.
