The driving steering engine 25 is arranged on the movable clamping seat 26, and the movable clamping seat 26 plays a role in supporting the driving steering engine 25. In addition, the movable clamping seat 26 also plays a role of a nut and is in threaded fit transmission with the screw rod 14, two ends of the screw rod 14 are supported by screw rod fixing supports 13a and 13b fixed on the supporting plate 8, one end of the screw rod is also connected with the second stepping motor 5 through a coupler 7, and the second stepping motor 5 is fixed on the supporting plate 8 through the second stepping motor fixing support 4.

The invention adopts the electromechanical combination technology to realize the automation of the blackboard erasing process. As shown in fig. 7, when the control switch is turned on, a program pre-inputted by the control system completes a set of actions such as automatic rolling, wiping, dust collection, etc. of the annular panel 1. In the relative motion process of rolling of the annular panel 1 and feeding of the blackboard eraser 10, the blackboard eraser realizes double strengthening effect, and the blackboard eraser is ensured to be cleaner. In addition, the control switch 18 can be divided into two stages, wherein one stage is used for controlling the above actions, and the other stage is used for controlling the operation of the eraser clutch mechanism, so that the eraser 10 is separated from the annular panel 1, the eraser 10 is convenient to take out for cleaning or replacing, or the blackboard-writing on the annular panel 1 is reserved. The object stage 6 is also used for placing other teaching aids.
