Utility model content
Technical problem to be solved in the utility model is for the above-mentioned state of the art, and the ellipsograph of the popularization that for a kind of elegant in shape, is easy to carry, is suitable for.
The utility model solves the problems of the technologies described above adopted technical scheme:
Ellipsograph, comprise handle and to be arranged on handle and the first supporting leg be hinged and the second supporting leg, needle tray is offered in first supporting leg lower end, needle tray internal fixtion is provided with intermediate plate, the first syringe needle is provided with in intermediate plate, wherein: the second supporting leg bottom is fixed with winding bracket, winding bracket is provided with clamping plate, a reel is folded with in clamping plate, clamping plate are outside equipped with clamping runner, reel can rotate in clamping plate, it is fixing that clamping runner energy clamping jaws makes clamping plate and reel rub, winding bracket bottom is provided with the second syringe needle, the lower end of the first syringe needle and the second syringe needle is provided with through wires hole, the winding of single line one end is on reel, the other end passes the through wires hole of the first syringe needle and the second syringe needle successively, be fixed on the first syringe needle place.
For optimizing technique scheme, the concrete measure taked also comprises:
Above-mentioned also comprises detail pen, and the nib place of detail pen is provided with groove, and detail pen blocks the line between the first syringe needle and the second syringe needle by this groove.
Above-mentioned detail pen is pencil.
Above-mentioned line is cotton thread.
The first above-mentioned syringe needle and the second syringe needle are stainless pin.
The utility model ellipsograph is a kind of divider calipers drawing ellipse, and it changes on the basis of traditional compasses profile and comes.The end of two of traditional compasses contact papers is made into, with can the draw point of threading, by draw point threading end sharpening, make not slide on paper.One end winding is on reel, and the other end passes the through wires hole of the first syringe needle and the second syringe needle successively, is fixed on the first syringe needle place.Reel is one can rotate the device that cotton thread can be wrapped in, with clamping plate as fork, reel is fixed, the degree of tightness determining clamping plate is rotated again with clamping runner, when making to need unwrapping wire, reel can rotate, and when drawing oval, reel is compacted, can not rotate, ensure that ellipse drawing obtains precisely.Between ellipsograph two summit, the distance of cotton thread is exactly the length of oval 2a, then two summit spacings be transferred to the length of 2c and be fixed on paper, being then close to cotton thread with a pencil and just can drawing oval, in order to non-off-line, at pencil plumbous point place groove at quarter one, cotton thread is placed on groove.
Ellipsograph is elegant in shape, is easy to carry.Be particularly suitable for student and drawing worker draws ellipse, be suitable for promoting, market prospects are considerable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of winding bracket.
Wherein, Reference numeral is: handle 1, first supporting leg 2, second supporting leg 3, needle tray 4, intermediate plate 5, first syringe needle 6, winding bracket 7, clamping plate 8, reel 9, clamping runner 10, second syringe needle 11, through wires hole 12, line 13, detail pen 14.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Ellipsograph, comprise handle 1 and to be arranged on handle 1 and the first supporting leg 2 and the second supporting leg 3 be hinged, needle tray 4 is offered in first supporting leg 2 lower end, needle tray 4 internal fixtion is provided with intermediate plate 5, the first syringe needle 6 is provided with in intermediate plate 5, wherein: the second supporting leg 3 bottom is fixed with winding bracket 7, winding bracket 7 is provided with clamping plate 8, a reel 9 is folded with in clamping plate 8, clamping plate 8 are outside equipped with clamping runner 10, reel 9 can rotate in clamping plate 8, it is fixing that clamping runner 10 energy clamping jaws 8 makes clamping plate 8 and reel 9 rub, winding bracket 7 bottom is provided with the second syringe needle 11, the lower end of the first syringe needle 6 and the second syringe needle 11 is provided with through wires hole 12, single line 13 one end winding is on reel 9, the other end passes the through wires hole 12 of the first syringe needle 6 and the second syringe needle 11 successively, be fixed on the first syringe needle 6 place.
In embodiment, also comprise detail pen 14, the nib place of detail pen 14 is provided with groove, and detail pen 14 blocks the line 13 between the first syringe needle 6 and the second syringe needle 11 by this groove.
