Adjustable blackboard

An adjustable blackboard solves the problem that students sitting at the two sides of a classroom can not see the board writing clearly because of the light reflection for the prior blackboard. The utility model is characterized in that a blackboard face (2) comprises two plane plates connected by a middle rotating shaft (3). The two sides of the blackboard face (2) are respectively provided with a telescoping rod (4). The blackboard is fixed on a wall (1) by the rotating shaft (3) and the telescoping rod (4).The blackboard position can be adjusted according to the incidence angle of sunlight so that the specula reflection light can not influence the students sitting at the two sides of the classroom.
