Abstract
The utility model relates to a kind of mathematical education blackboard eraser, comprise blackboard eraser body, the front end of described blackboard eraser body is provided with the adhesive hair for blackboard wiping, two ends up and down at blackboard eraser body are provided with suction block near adhesive hair place, the front end of described suction block is provided with for being adsorbed on the sucker on blackboard, the upper and lower two ends, side of described blackboard eraser body are provided with magnet, the rear end of described blackboard eraser body is fixed with pole, described pole comprises tuning pipe and holding rod, described tuning pipe is fixed on the rear end of blackboard eraser body, offers several louvres on described holding rod.The utility model is reasonable in design, by being provided with sucker, when erasing the board, because sucker is adsorbed on blackboard, keeps like this adhesive hair and blackboard close contact, can low weight loose ground by chalk dust wiping, do not leave a trace; By magnet is set, can be adsorbed on magnet board simultaneously, prevent descending slowly and lightly of dust.
Description
Technical field
The utility model relates to teaching apparatus for mathematics field, relates in particular to a kind of mathematical education blackboard eraser.
Background technology
Along with scientific and technological progress and the raising to teaching requirement, the environment of education activities also needs to improve.At present, the blackboard that China school is used remains take traditional blackboard as main, and the wiping method of this blackboard is hand-held blackboard eraser, wiping repeatedly on blackboard.The wiping operation method of this blackboard eraser is not only time-consuming but also require great effort, and while erasing the board, tedious chalk dust can dance in the air all over the sky, drops on desk, before dais, is even inhaled in people's body, affects mood, more unhealthful.Because attend class every day, will write writing on the blackboard, erase the board, chalk dust often makes with dishevelled hair and a dirty face teacher.Although chalk dust there is no large evil to human body, however the millions of teacher of China, and all will do writing on the blackboard with chalk every day, all lives in every day in the chalk dust after erasing the board, and still can cause nose, pharynx, throat's discomfort.
Blackboard eraser of the prior art is in the process erasing the board, if the application of force is large not, very difficult that blackboard eraser is clean, can leave chalk trace, can require great effort very much like this, and giving erases the board has brought inconvenience.
Utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of mathematical education blackboard eraser is provided.
The utility model is to be achieved through the following technical solutions:
A kind of mathematical education blackboard eraser, comprise blackboard eraser body, the front end of described blackboard eraser body is provided with the adhesive hair for blackboard wiping, two ends up and down at blackboard eraser body are provided with suction block near adhesive hair place, the front end of described suction block is provided with for being adsorbed on the sucker on blackboard, and the upper and lower two ends, side of described blackboard eraser body are provided with magnet.
As optimal technical scheme of the present utility model, the rear end of described blackboard eraser body is fixed with pole, and described pole comprises tuning pipe and holding rod, is convenient to hand-held.
As optimal technical scheme of the present utility model, described tuning pipe is fixed on the rear end of blackboard eraser body.
As optimal technical scheme of the present utility model, on described holding rod, offer several louvres.
Compared with prior art, the beneficial effects of the utility model are: the utility model is reasonable in design, by being provided with sucker, when erasing the board, because sucker is adsorbed on blackboard, keep like this adhesive hair and blackboard close contact, can low weight loose ground by chalk dust wiping, do not leave a trace; By magnet is set, can be adsorbed on magnet board simultaneously, prevent descending slowly and lightly of dust.
