Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：
1- clipboards, 2- litter, 3- sliding blocks, 4- blackboard erasers, 5- supports, 6- bases, 7- universal wheels, 8- arrestment mechanisms, 9- rotations
Rotating shaft, 10- swingles, 11- pie chart disks, 12- scale values, 13- is around axle, 14- scales.
Embodiment
The utility model is elaborated below in conjunction with the accompanying drawings.
As shown in figure 1, the Multifunctional combined teaching aids that a kind of international trade teaching of the present utility model is used, including clipboard
1st, litter 2, sliding block 3, blackboard eraser 4, support 5, base 6, universal wheel 7, arrestment mechanism 8, rotary shaft 9, swingle 10, pie chart disk 11,
Scale value 12, around axle 13, scale 14；
The upper and lower ends of clipboard 1 are respectively equipped with horizontally disposed litter 2, and any litter 2 is provided with and is slidably connected with it
Sliding block 3, the upper and lower ends of blackboard eraser 4 be separately fixed above and below on two sliding blocks 3, the wiping surface of blackboard eraser 4 and the writing of clipboard 1
Face offsets；
One end of swingle 10 is arranged on the back of clipboard 1 by rotary shaft 9, and the other end of swingle 10 is fixed with
Pie chart disk 11, the marginal position of pie chart disk 11 is provided with angle index value 12, and one end of scale 14 is with being arranged on the center of pie chart disk 11
Be rotatably connected around axle 13, the other end extends to the marginal position of pie chart disk 11.
The clipboard 1 is fixedly installed on base 6 by support 5, and the bottom of base 6 is arranged with universal wheel 7.
The course of work of this example：
Write teaching notes in use, being submitted a written statement to a higher authority in clipboard 1, during wiping, left and right pulls blackboard eraser 4, and time saving and energy saving, wiping is finished
Afterwards, blackboard eraser 4 is moved to the left end or right-hand end of clipboard 1, does not influence to reuse.
During international trade is given lessons, it is necessary to be explained using substantial amounts of pie chart, it is necessary to during using pie chart, rotating rotary rods
10 cause pie chart disk 11 be located at clipboard 1 surface, can be drawn along scale 14 it is some from the center of pie chart disk 11, to pie chart
The line segment that the marginal position of disk 11 is terminated, according to the angle index value 12 indicated on pie chart disk 11, scale 14 is rotated to different
Position, draws straight line, pie chart disk 11 can be thus divided into some different size of sectors, for representing shared by disparity items
Ratio, can so save it is substantial amounts of drafting pie chart time.When pie chart disk 11 is on the shelf, rotated to clipboard 1
Back, saves space.
The setting of universal wheel 7, is easy to move the present apparatus, high using flexibility ratio.
One embodiment of the present utility model is described in detail above, but the content is only of the present utility model
Preferred embodiment, it is impossible to be considered as being used to limit practical range of the present utility model.It is all to be made according to present utility model application scope
Equivalent change with improve etc., all should still belong within patent covering scope of the present utility model.
