Abstract
The utility model discloses a tooling scale comprises a ruler, a protractor, space patterns and arc laces. The utility model is characterized in that hollow mathematic operation symbols are arranged below the scales of the tooling scale. The adoption of the tooling scale with mathematic operation symbols enables teachers to use the mathematic operation symbols very conveniently when scoring wax plate paper to prepare comparatively regular paper for tests and exercises. The utility model solves the problem of existing tooling scales and has the advantages of simple structure, convenient use and so on.
Description
Technical field
The utility model relates to a kind of schooling apparatus.
Background technology
The schooling apparatus that existing market is sold, it all is single sale and use that ruler, protractor, the compasses of band scale are arranged respectively, the ruler size broad that has, there are a plurality of empty graphics the centre, and empty graphic is respectively triangle, rectangle, trapezoidal, square, ellipse etc.These schooling apparatus all are the schooling apparatus at the student, but in some zone, teacher also needs to carve waxed cardboard with hand, to be used for manual mimeograph paper and exercise volume, need a kind of with using with the tool ruler of oeprator is convenient for this reason.
Summary of the invention
It is a kind of with the tool ruler with oeprator that the utility model provides.
For achieving the above object, the technical solution of the utility model is:
A kind of tool ruler comprises ruler, protractor, space diagram and arc lace, is characterised in that, has the mathematical operation symbol of hollow out below the scale of tool ruler.
The utility model is a teacher and carves stencil plate paper owing to adopt the tool ruler of band with oeprator, can use these mathematic signs very easily, carves more regular paper and exercise volume.Solve existing tool ruler and can not origin carve the problem of waxed cardboard, and had characteristics such as simple in structure, easy to use.
Description of drawings
Fig. 1 is the schematic diagram that this practicality is newly moulded.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1, a kind of tool ruler comprises ruler 1, protractor 3, space diagram 4 and arc lace 5, is characterised in that, has the mathematical operation symbol 2 of hollow out below the scale of tool ruler.The left side is a protractor 3, and the right is the ruler 1 of band scale, the size broad of ruler 1, the top has scale, be processed with the space diagram 4 of different shape below the mathematical operation symbol 2 that has hollow out below the scale of tool ruler, scale limit, tool ruler bottom is an arc lace 6.This multifunctional learning tool ruler is a transparent plastic material, adopts Mould Machining to be shaped, and protractor 3 can the measuring angle size, and ruler can be drawn the right angle, and space diagram 4 can be drawn triangle, square, trapezoidal etc., and arc lace 6 can be drawn the arc lace.The utility model is a teacher and carves stencil plate paper owing to adopt the tool ruler of band with oeprator, can use these mathematic signs very easily, carves more regular paper and exercise volume.Solved the problem that existing tool ruler can not origin be carved wax value plate.
