Description
Technical field
The utility model relates to multipurpose ruler, belongs to the realia technical field.
Background technology
In daily teaching, teacher often can use multiple aid, and like ruler, set square, compasses etc., there is following shortcoming in these educational aids: the first, owing to need multiple instrument, so just increased the expenditure of school; The second, because the shape of every kind of educational aid all is different, it is very big to take up room when depositing like this; The 3rd, because every kind of instrument all separates separately, seek very inconvenient like this; The 4th, because the effect of every kind of instrument is all more single, will cause the very big wasting of resources like this.
Summary of the invention
The purpose of the utility model is to solve the weak point that above-mentioned prior art exists, and a kind of reasonable in design is provided, different geometric multipurpose rulers as required can draw.
The utility model is realized through following technical scheme:
A kind of multipurpose ruler, its special character are to comprise main scale 1 and secondary chi 2, are connected through rotating shaft 3 between main scale 1 and the secondary chi 2, and main scale 1 is provided with graduation mark 4, and graduation mark 4 lower ends are provided with the hollow hole 5 that is used to place writing implement, and secondary chi 2 is provided with angle line 6.
The multipurpose ruler of the utility model with the use that is integrated in one of various drawing tools, has so not only been practiced thrift resource, has reduced school's expenditure, brings very big help also on class efficient, and can fold, and has reduced taking up room, and greatly facilitates daily teaching and uses.
Description of drawings
Fig. 1: the utility model multipurpose ruler structural representation;
Among the figure: 1: main scale; 2: secondary chi; 3: rotating shaft; 4: graduation mark; 5: hollow hole; 6, angle line.
The specific embodiment
Provide the specific embodiment of the utility model below with reference to accompanying drawing, be used for the formation of the utility model is done further explain.
The multipurpose ruler of present embodiment comprises main scale 1 and secondary chi 2, is connected through rotating shaft 3 between main scale 1 and the secondary chi 2, and main scale 1 is provided with graduation mark 4, and graduation mark 4 lower ends are provided with the hollow hole 5 that is used to place writing implement, and secondary chi 2 is provided with angle line 6.
During use, can chalk be inserted in the hollow hole, can draw according to the angle line on the secondary chi when drawing triangle, when drawing circular arc, the angle line that can draw earlier gets final product main scale being rotated to the respective angles line.The overall dimensions of present embodiment is dwindled, also go for the daily study of student and use.
The multipurpose ruler of present embodiment with the use that is integrated in one of various drawing tools, has so not only been practiced thrift resource, has reduced school's expenditure, brings very big help also on class efficient, and can fold, and has reduced taking up room, and greatly facilitates daily teaching and uses.
