Abstract

The utility model discloses a foldable blackboard eraser. The foldable blackboard eraser comprises a first blackboard eraser body (1), a second blackboard eraser body (2) and bristles (3), wherein the first blackboard eraser body (1) and the second blackboard eraser body (2) are the same in shape and size; grooves (5) are formed in the middle of the first blackboard eraser body (1) and that of the second blackboard eraser body (2); the bristles (3) are movably connected with the interiors of the grooves (5); the flange on the first blackboard eraser body (1) and that on the second blackboard eraser body (2) are in hinge connection with each other; and when the foldable blackboard eraser is folded, the groove (5) of the first blackboard eraser body (1) and that of the second blackboard eraser body (2) correspond to each other in position, and water-absorbing sponges (4) are arranged on the first blackboard eraser body (1) and the second blackboard eraser body (2) and at the backs of the bristles (3). As the bristles (3) are arranged in the grooves (5) on the first blackboard eraser body (1) and the second blackboard eraser body (2), and the water-absorbing sponges (4) are arranged on the backs of the bristles (3), the foldable blackboard eraser can be used in such a manner that when the two blackboard eraser bodies are unfolded, and a bolt (6) is well plugged, a blackboard is erased by the bristles (3), and then erased by the water-absorbing sponges (4), so that the quantity of falling down chalk dust can be reduced; and after the use of the foldable blackboard eraser, the first blackboard eraser body (1) and the second blackboard eraser body (2) are folded, so as not to dirty the place where the foldable blackboard eraser is placed, and achieve a sanitary and dust-absorbing effect.

Description
