The gear two of hawk jack-up, is connected by rotating mechanism between described gear two and gear one；
This utility model advantage compared with prior art is: wiping blackboard structure of the present utility model is simple, convenient to be used, and can have in use
Effect the dust near blackboard eraser is drawn onto on filter, and stick to the dust on hairbrush and by playing apparatus for ash, dust bullet can be fallen, it is simple to operate,
And dust can collect and economize on resources from new utilization.
As improvement, described rotating mechanism includes the axle one being arranged on gear one, the axle two being arranged on gear two, and a described axle part sets
Being set to screw-rod structure, described screw rod coordinates with gear two, in 90 ° between described axle one and axle two, this kind of simple and practical convenience.
As improvement, the described number playing hawk is 4, and uniform arranges in the enclosure, play the number of hawk be 4 can quickly by
Dust bullet on hairbrush falls, and practical function is more preferable.
As improvement, described housing is divided into upper shell and lower house, for removably connecting between described upper shell and lower house, removably connects
Upper-lower casing can be separated, easy cleaning filter.
As improvement, described bullet hawk is grid shaped board, and grid shaped board chalk dust can fall from grid, and cleaning effect is more preferable.
