| description | The invention discloses a blackboard capable of achieving turnover. The blackboard capable of achieving turnover comprises a left frame and a right frame. An extending end is arranged at the right endof the left frame, and a fixed shaft I is fixedly arranged at the extending end. A rotating sleeve I is fixedly arranged at the left end of the right frame and connected with the fixed shaft I in a rotating mode through a bearing. Two fixing supports are arranged in the left frame, two fixing supports are arranged in the right frame, blackboard bodies are fixedly arranged in the two fixing supports of each frame, and the two blackboard bodies in each frame can rotate. By the adoption of the blackboard capable of achieving turnover, the usable area of the blackboard is increased, and a teacherdoes not need to frequently clean the blackboard advantageously.
