Abstract
The utility model relates to a drawing instrument, in particular to a multifunction drawing gauge which is provided with a drawing leg and a positioning leg, wherein, the upsides of the drawing leg and the positioning leg are hinged with each other. The utility model is characterized in that the lower rim of the outer side of the drawing leg is provided with a ruler; the inner side of the upside of the drawing leg is provided with a semicircular protractor, the central point of the median of the protractor and the hinged point of the upsides of the drawing leg and the positioning leg are overlapped; the upside of the positioning leg relative to the upside of the drawing leg is provided with a readout window which is provided with positioning graduation marks. The utility model integrates the functions of a triangle, the protractor, the ruler and compasses, overcomes the shortcoming of inconvenient carrying of drawing tools in the prior teaching and learning, reduces production procedures, saves raw materials, and is capable of being used either as a teaching tool for teachers or a learning tool for students.
Description
Technical field: the utility model relates to a kind of plotting apparatus, specifically a kind of multi-functional divider calipers.
Background technology: well-known, now in the middle and primary schools teacher teaching and student when doing one's assignment, the drawing instrument that uses generally includes compasses, set square, protractor and ruler, its weak point be each function singleness, use and carry inconvenience, manufacturing cost is high.
Summary of the invention: the purpose of this utility model provides a kind of have multiple function, use and multi-functional divider calipers very convenient to carry.
The utility model can reach by following measure:
A kind of multi-functional divider calipers, be provided with setting-out leg and location leg, the upper end of setting-out leg and location leg is hinged, it is characterized in that lower edge, setting-out leg outer side limit is provided with ruler, setting-out leg upper end inner side edge is provided with semicircle protractor, straight warp central point of protractor and pin joint coincide, and leg top, location is provided with the reading window with respect to protractor place, setting-out leg upper end, and reading window limit is provided with the location scale mark.
The utility model is owing to adopt said structure, make it integrate the function of set square, protractor, ruler, compasses, overcome that drawing instrument carries and use inconvenient deficiency in existing teaching, the study, and reduced production link, saved a large amount of raw materials for production, both can make teacher's teaching aid, can make student's learning tool again.
Description of drawings:
Fig. 1 is a structural representation of the present utility model, also is the structural representation of a kind of embodiment.
Embodiment: the utility model is further described below in conjunction with accompanying drawing:
As shown in the figure, a kind of multi-functional divider calipers, be provided with setting-out leg 1 and location leg 2, the lower end of setting-out leg 1 is provided with paintbrush clamper 3, the lower end of location leg 2 is provided with needle-like angle 4, the upper end of setting-out leg 1 and location leg 2 is hinged with a fastening bolt 5, setting-out leg 1 outer side edges lower edge is provided with ruler 6, setting-out leg 1 upper end inner side edge is provided with semicircle protractor 7, protractor 7 is provided with the angle groove, protractor 7 straight warp central points and pin joint coincide, and leg 2 tops, location are provided with reading window 8 with respect to protractor 7 places of setting-out leg 1 upper end, and reading window limit is provided with location scale mark 9.
The utility model integrates the function of set square, protractor, ruler, compasses, has overcome existing religion Learn, drawing instrument carries and uses inconvenient deficiency in the study, and reduced production link, saved A large amount of raw materials for production have that function is many, easy to carry, simple operation and other advantages, both can do teacher's religion Instrument can be done again student's schooling apparatus.
