Angle table, first main scale and the second scale surface bottom are pasted with graduation apparatus respectively, and the first main scale reverse side passes through
One telescopic is socketed with the first expansion plate, and the second main scale reverse side is socketed with the second expansion plate by the second telescopic, described
First expansion plate end is provided with the pen cap, and the second expansion plate end is provided with positioning body.
Further, the anglec of rotation of first main scale and the second main scale is 0-90 degree.
Further, the rotary shaft is adjustable-tightness device.
Further, first connector be groove-like, and with the second connector pivot bush unit.
Further, the second connector end is provided with angle indicator.
Further, first expansion plate is symmetrical arranged with the second expansion plate.
The utility model has the advantages and positive effects of：Because the utility model is by setting the first main scale, second
Main scale and graduation apparatus so that teacher conveniently draws the straight line of designated length, by setting the first expansion plate and the second expansion plate, make
Teacher is needed when drawing longer straight line, it is stretchable go out expansion plate, simply and conveniently, by setting rotary shaft, the first connection
Part, the second connector and angle table so that teacher can easily draw the triangle of specified angle, while being also convenient for measurement folder
The angle at angle, by setting the pen cap and positioning body, facilitates teacher and draws different size of circle；Simultaneously compared to more traditional system
A variety of functions are integrated by figure instrument, the utility model, and are convenient for carrying, while greatly improving the teaching effect of teacher
Rate.
Brief description of the drawings
Fig. 1 is the front view that the utility model embodiment is provided；

Embodiment
For invention, features and effects of the present utility model can be further appreciated that, following examples are hereby enumerated, and coordinate
Accompanying drawing describes in detail as follows.
It is explained in detail with reference to the structure of Fig. 1-3 pairs of Mathematical multipurpose rulers of the present utility model.It is a kind of new
Versatile ruler, including the first main scale 1, the second main scale 2 and rotary shaft 3, described one end of first main scale 1 and the one end of the second main scale 2
It is hinged by rotary shaft 3, the anglec of rotation of the main scale 2 of the first main scale 1 and second is 0-90 degree, and the rotary shaft 3 is adjustable
Take-up is saved, the surface middle part of the first main scale 1 riveting has the first connector 4, and the surface middle part of the second main scale 2 riveting has
Second connector 5, the inner chamber of the first connector 4 is connected with the surface of the second connector 5 using socket, first connector 4
For groove-like, and with the pivot bush unit of the second connector 5, the top of the first connector 4 pastes angled table 6, and described second connects
The end of fitting 5 is provided with angle indicator, and the surface lower portions of 1 and second main scale of the first main scale 2 are pasted with graduation apparatus 7 respectively, described
The reverse side of first main scale 1 is socketed with the first expansion plate 8 by the first telescopic 12, and the reverse side of the second main scale 2 is flexible by second
