Description
technical field:
the utility model relates to a kind of for mathematical education multifunctional ruler.
background technology:
mathematics Curriculum is a required basic theory class of university's each specialty of science and engineering subject, is basic quality for cultivating student, learns the service of follow-up course.But, the teaching aid relating in mathematical education process is at present few, when preparing lessons, teacher often need ruler to draw and mark correlated knowledge point and some simple data of calculating etc., tradition ruler is that structure is very simple, and oblong-shaped has scale on one side, and be often used in conjunction with at use procedure needs and protractor, but both have usually separately brought a lot of inconvenience so when in use, have delayed the time, affect service efficiency.
summary of the invention:
the purpose of this utility model is to provide a kind of for mathematical education multifunctional ruler.
above-mentioned object realizes by following technical scheme:
a kind of for mathematical education multifunctional ruler, its composition comprises: wooden chi body, described middle, wooden chi body upper end has puts a groove, above described wooden chi body left end, there is calculator, before described wooden chi body, there is slide-rule dial line, after described wooden chi body, there is wave, on described limit, calculator left side, there is through hole A, described wooden chi body right-hand member has pencil sharpening device, described pencil sharpening device is fixed on wooden chi body by screw, described wooden chi body right flank has through hole B, described wooden chi body left surface has square mouth, in described square opening, there is protractor, in described wooden chi body, there is lead for retractable pencil chamber, described lead for retractable pencil chamber has rubber capping.
described for mathematical education multifunctional ruler, described calculator has display screen and button, and described display screen button is arranged on above wooden chi body left end, and described protractor bottom has through hole C, and described through hole A is connected by rotating shaft with through hole C.
the beneficial effects of the utility model:
1. the utility model chi body is wooden, in the process that can prevent from using teacher, there is static, on wooden chi body, there is pencil sharpening device and calculator, when can facilitating teacher to use, sharpen a pencil and calculate, be provided with protractor in left end simultaneously, protractor can be taken out and be carried out angulation measurement by rotating shaft from square orifice, does not so just need to carry separately protractor.
2. the utility model is provided with slide-rule dial line and wave in front and back, and teacher can draw straight line also can draw wave simultaneously, and separator can be carried out with two kinds of lines in places different on teaching notes.
3. chi needs certain thickness, common chi is solid, the space of the utility model handle increase thickness is as memory space and inlay space, after thickening, not only there is original function, increase storage effect, also increased the rigidity of chi, although be not shocking breakthrough, be unprecedented really.
4. the utility model is simple, multiple functional, and a chi is multiplex, easy to operate.
brief description of the drawings:
accompanying drawing 1 is structural representation of the present utility model.
accompanying drawing 2 is structural representations of the utility model protractor.
detailed description of the invention:
embodiment 1:
a kind of for mathematical education multifunctional ruler, its composition comprises: wooden chi body 13, described middle, wooden chi body upper end has puts a groove 5, above described wooden chi body left end, there is calculator 3, before described wooden chi body, there is slide-rule dial line 9, after described wooden chi body, there is wave 4, on described limit, calculator left side, there is through hole A14, described wooden chi body right-hand member has pencil sharpening device 6, described pencil sharpening device is fixed on wooden chi body by screw 7, described wooden chi body right flank has through hole B8, described wooden chi body left surface has square mouth 1, in described square opening, there is protractor 12.In described wooden chi body, have lead for retractable pencil chamber 15, described lead for retractable pencil chamber has rubber capping.
