Wide direction is equipped with annular rectangular channel, and the annular rectangular channel is internally provided with hairbrush, and the upper surface of the substrate passes through fixation
Glue sticking has felt, and is bonded with hairbrush, and the outside of the hairbrush is equipped with ring-shaped lever support, and the ring-shaped lever support is along long
The both ends central bottom in degree direction is provided with fixing piece, the fixing piece with lever annular support by fixed pin connection, it is described
The upper end of fixing piece is provided with converse force block.
Further, the outside interplanar distance of the annular rectangular channel and substrate is 3-4mm, and the groove depth of the annular rectangular channel is
1.5-2mm。
Further, the height of the hairbrush covers low 1-2mm than the leakage of anti-dust.
Further, the spacing between the lever annular support and hairbrush is 0.5-1mm, the lever annular support with it is anti-
Spacing between dust leakage set is 0.5-1mm.
Further, the fixing piece passes through fixed glue sticking with substrate.
Further, setting is fluted among the both sides of the felt, and the groove matches with converse force block.
With the above structure, the beneficial effects of the utility model are：The utility model is simple in structure, reasonable design, leads to
Converse force block is crossed as wiping direction swings back and forth, lever annular support is caused to strut the side of anti-dust leakage set and make another
Side is tightened, and by dust collection in anti-dust leakage set, hairbrush can in blackboard eraser motion process for mechanical movement in this way
Dancing in the air for dust is reduced, has the effect of environmental protection, reduces environmental pollution, be conducive to the physical and mental health of teachers and students.

Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and specifically
Embodiment, the present invention will be further described in detail.It should be appreciated that the specific embodiments described herein are only used
To explain the utility model, it is not used to limit the utility model.
Shown in Fig. 1 to Fig. 4, present embodiment uses following technical scheme：A kind of novel blackboard eraser, including inverse
Anti- force block 1, felt 2, fixed pin 3, lever annular support 4, fixing piece 5, hairbrush 6, substrate 7, annular rectangular channel 7-1, anti-powder
Dirt leakage set 8, the substrate 7 are rectangular shape, and the outside of the substrate 7 is enclosed with anti-dust leakage set 8, the substrate 7
Upper surface be equipped with annular rectangular channel 7-1 along the long wide direction of its profile, the annular rectangular channel 7-1's is internally provided with hairbrush
6, the upper surface of the substrate 7 is bonded with felt 2 by fixing glue, and is bonded with hairbrush 6, and the outside of the hairbrush 6 is equipped with ring
Shape lever support 4, the both ends central bottom of the ring-shaped lever support 4 along its length are provided with fixing piece 5, the fixing piece
5 are connect with lever annular support 4 by fixed pin 3, and the upper end of the fixing piece 5 is provided with converse force block 1.
