Description
Technical field:
The utility model relates to a kind of attending classes, drawing appliance.Be specially adapted to the multi-functional gusset chi that students in middle and primary schools use.
Background technology:
Well-known, attending classes and drawing appliance all are that number of packages is many by the supporting use of set square, ruler, protractor and compasses, preserve and use inconvenience.By literature search, application number: 99229095,3 titles: multifunctional student chi.Be characterized in being made up of main scale and auxilliary chi, an end of rectangle main scale is provided with protractor, is provided with the auxilliary chi that can be superimposed with this protractor place main scale by rotating shaft on protractor, establishes compass, magnifying glass, tape measure and lead box on the chi body.Shortcoming is a complex structure, the cost height, and students in middle and primary schools are inapplicable.
Summary of the invention:
In order to overcome the shortcoming of original technology, the purpose of this utility model is a kind of simple in structure, cheap, preservation of design, multi-functional gusset chi easy to use.
The utility model is achieved through the following technical measures, a kind of multi-functional gusset chi, it is characterized in that 45 chi and the rectangle ruler that is provided with 30 °, 150 ° angles are connected as a single entity, on the 45 chi, be provided with protractor, per 0.25 centimeters is established small sircle hole on rectangle ruler one side 0-10 centimeter scale, establish two by touching circular hole in protractor center line both sides, on the plane of 45 chi and rectangle ruler, establish 40 square holes that vary in size.
The advantage of this multi-functional gusset chi be the function of comprehensive multiple function angle square in a chi, gusset chi upper aperture is enclosed within the answer of standardization examination examination paper and selects on the square hole, with pen fill out draw after, avoid misunderstanding topic, fill out wrong going.Simple in structure, with low cost, preserve, easy to use, multiple functional, adapt to and produce in batches.
Description of drawings:
Fig. 1: multi-functional gusset chi schematic diagram
1 45 chi, 2 protractors, 3 rectangle rulers, 4 pattern square holes, 5 small sircle holes, 6 pattern circular holes
The utility model be by 45 chi (1) with become one with the rectangle ruler (3) at 30 °, 150 ° angles, on the 45 chi, establish protractor (2), on rectangle chi one side 0-10 centimeter scale, establish small sircle hole (5) for per 0.25 centimetre, establish pattern circular hole (6) in the center line both sides of protractor (2), on the plane of 45 chi and rectangle ruler, establish 40 and vary in size by touching square hole (4)
Specific embodiments:
Can be with 45 chi (1) 45 °, the 90 ° angles of directly drawing when the utility model uses.With 45 chi (1) and rectangle ruler (3) 30 °, 60 °, the 150 ° angles of drawing.Use amount hornwork (2) can be measured and paint 180 ° of each angles of angle.In the small sircle hole (5) of 0-10 centimeter scale, insert sharp shaped material and do the center of circle, other root nib is inserted in the small sircle hole of any scale and make radius, realize the effect of compasses.Each square hole on 45 chi (1) and rectangle ruler (3) plane is to be enclosed within on the standardization examination answer choice box.
