Abstract
The invention discloses an up-down push-pull-type blackboard eraser convenient and fast to use. A blackboard eraser body 1 is assembled on the front face of a blackboard 1, and a blackboard eraser body 2 is assembled on the back face of a blackboard 2. The blackboard eraser body 1 and the blackboard eraser body 2 are fixedly connected with a connecting rod 1 and a connecting rod 2 separately. Each connecting rod penetrates through a corresponding sleeve and can make axial movement in the sleeve, and the moving position can be fixed by a screw penetrating through the connecting rod to be fixed to the corresponding sleeve. When the blackboard 1 is pulled down, if contents on the blackboard 2 are expected to be erased, the corresponding connecting rod can be pulled to make the blackboard eraser body 1 compress and touch the blackboard 2, and at the moment, the contents on the blackboard 2 can be erased while the blackboard 1 is pulled down. If the contents on the blackboard 2 are expected to be reserved, the corresponding connecting rod can be pulled to make the blackboard eraser body 1 be separated from the blackboard 2. As for contents on the blackboard 1, the same principle can be adopted. Therefore, by means of the up-down push-pull-type blackboard eraser convenient and fast to use, after blackboard writing is completed, a teacher can be helped to selectively complete blackboard cleaning work in the process of pushing and pulling the blackboards up and down, the burdens on the teacher are relieved, and class hours can be saved.
Description
Technical field
The present invention relates to a kind of convenient blackboard eraser suitable for type of push and pull up down blackboard, belong to teaching aid field.
Background technology
At present, erasing the board needs the teacher to carry out manually, if required writing on the blackboard is more on classroom, frequently erasing the board will increase the burden of giving lessons of teacher；If blackboard panel is larger simultaneously, the time for erasing the board can be more long, in nervous atmosphere of attending class, is unfavorable for the efficient utilization of time.
Existing automatic blackboard eraser is only applicable to whole face formula blackboard, can only together wipe whole plate face, and the type of push and pull up down blackboard for just commonly using at present is not suitable for thus.
