Dynamic, teacher is purposeful, the study of planned and organized ground guiding student and grasp cultural and technical knowledge and technical ability, promotion student are plain
Matter improves, and them is turned into the people required for society, imparts knowledge to students and very important effect is played in the development of human civilization, it is pushed away
Great scientific and technological progress is moved.Twentieth century scientific and technological progress is certain to the great variety that human being's production and life are brought
Make us praising again and again." person who can hear voices a long way off " that always people have fantasies of from the ancient times, " prying eyes ", " airflight " and " flies to
Space " all becomes a reality in this century.The great scientific and technological progress of twentieth century is looked back, following project is undoubtedly shadow
Maximum is rung, and the prediction of mathematics and impetus are very crucial.
But existing mathematical education with servicing unit also there is in place of some shortcomings, the content that teacher teaches in classroom
It is limited, therefore teacher is nearly all to catch every point of time per second to give lessons, but most lose time when being erased the board undoubtedly on classroom
, and if chalk dust imprudence fall into the respiratory tract of human body, be likely to result in respiratory tract infection, existing blackboard is nearly all
Teacher holds blackboard eraser, therefore teacher can remain substantial amounts of chalk dust on hand, and human body is damaged for a long time.
The content of the invention
The invention aims to solve shortcoming present in prior art, and a kind of middle-school mathematics teaching proposed is used
Servicing unit.
To achieve these goals, present invention employs following technical scheme：A kind of middle-school mathematics teaching servicing unit,
Including the 3rd blackboard and firm banking, the firm banking side is by connecting rod with rotating axis connection, and the side of rotary shaft
Multiple universal wheels are provided with, the crown center opening position of the firm banking is provided with fix bar, and the inside of fix bar passes through
Fixture block is connected with expansion link, and dust disposable box is provided with the top of the fix bar, and is provided with the top of dust disposable box
Three blackboards, the both sides of the 3rd blackboard are slidably connected by chute with sliding block, and the side of sliding block passes through connecting shaft and blackboard
Cleaning wiping cloth connects, and the back of the 3rd blackboard is provided with hairbrush, and to be provided with slidable first black for the side of the 3rd blackboard
Plate, the side of first blackboard is provided with fixed plate, and the side of fixed plate is provided with slidable second blackboard.
As further describing for above-mentioned technical proposal：
The chute offers two altogether, and two chutes are symmetrical on the vertical center line of the 3rd blackboard.
As further describing for above-mentioned technical proposal：
The fix bar is provided with two altogether, and two fix bars is highly consistent.
As further describing for above-mentioned technical proposal：
The height of the expansion link is consistent with the height sum of two fix bars.
As further describing for above-mentioned technical proposal：
XTL-100 electric expansion bars are provided with the top of the blackboard eraser wiping cloth (rags).
In the present invention, first, blackboard eraser wiping cloth (rags) is provided with the top of the 3rd blackboard, and the back of the 3rd blackboard is provided with use
In the hairbrush for wiping the first blackboard, meanwhile, the back of fixed plate is provided with the hairbrush for wiping the second blackboard, then such to set
Be equipped with can so that teacher should not hand can realize the wiping of blackboard automatically, it is simple in construction, it is easy to operate, and the available face of blackboard
Product will not also reduce, and practicality is wide, and secondly, the back of the 3rd blackboard is provided with contractile second blackboard and the first blackboard, and
The side of firm banking sets multiple universal wheels by connecting rod with rotating axis connection, the side of connecting shaft, then universal wheel can use
Carry out freely activity, the second blackboard and the first blackboard are collapsible, therefore such set causes the teaching auxiliary device freely to move
It is dynamic and collapsible, it is not take up too big space.
