Description
Technical field
The utility model relates to a kind of stationery, especially a kind of Napier's compasses.
Background technology
Compasses are to be used for the instrument of draw circles or circular arc in mathematics and drawing, are usually used in construction with ruler and compasses.Compasses are made of metal usually, comprise can adjusting the angle between two parts by hinged two parts.
In construction with ruler and compasses, generally need to use ruler, pencil, rubber etc. to match, and various tool is separate, needs supporting purchase also to carry simultaneously, to guarantee smooth mapping.But Chang Fashengyin lacks certain or multiple drawing tool and influences the situation of mapping effect in daily study, work, makes troubles for study, work.
The utility model content
Influence the problem of mapping effect in order to solve because of lacking certain or multiple construction with ruler and compasses instrument, the utility model provides a kind of Napier's compasses, and it integrates rubber, ruler, compasses function, efficiently solves the problems referred to above.
In order to realize that the technical scheme that the utility model purpose is adopted is: a kind of Napier's compasses is characterized in that: it is made of compasses, rubber; Described compasses comprise holding rod, securing member, rotation pin, centre pin, handwriting.Holding rod is provided with external screw thread, and the upper end of lower end and securing member is fixed by screw thread; The securing member front is provided with groove, and the holding screw embedded groove is interior and will rotate pin, the centre pin top is fixed; The described rotation pin other end and handwriting are connected and fixed by bolt; The described centre pin other end is fixed with needle point, and the right side is provided with graduation mark, and its outer and the securing member back side are in the same plane; Described rotation pin and centre pin top are connected through the hinge; Described rubber is a hollow cylindrical, and is provided with internal thread, by thread bush on holding rod.
The beneficial effects of the utility model are: rubber, ruler are integrated mutually with compasses, can realize the function that the three has separately simultaneously, avoid influencing the mapping effect, bring convenience for study, work, be applicable to the student and need to use the working clan of construction with ruler and compasses because of lacking certain instrument.
