Description
Technical field
The utility model relates to a kind of compasses, is specifically a kind ofly can draw circle, can draw oval novel ellipsograph again.
Background technology
Compasses are the often practical schooling apparatus of middle school student, the instrument that often uses when also being engineering drawing.The general at present compasses that use generally can not be drawn ellipse, can only draw circle.Recently also occur some and can draw oval compasses, but their structure more complicated, oval major and minor axis is not easy to regulate, and therefore the oval size range of drawing is smaller, uses very inconvenient.
Summary of the invention
Technical problem to be solved in the utility model is: the defective at the said goods exists provides a kind of novel bow compass to remedy the deficiency of the said goods.
The technical solution of the utility model is achieved in that it comprises compasses and oval assistor, oval assistor comprises rolling bearing, rolling bearing is fixed on the top of compasses, be fixed with support on the rolling bearing, oval paintbrush is equipped with in activity on the cross bar of support, be connected with movable push bar between oval paintbrush and the rolling bearing, two legs of compasses are provided with fairlead.The lower end of oval paintbrush is provided with the lead-in wire groove.A leg of compasses is provided with movable nib, and another leg of compasses is provided with lead-in wire and reclaims fixator; Movable push bar is provided with spring; One end of support is provided with rotary handle.
The utlity model has advantage simple in structure, easy to use, it can easily draw the circle and the ellipse of various sizes, and it is very convenient to regulate dismounting, is suitable as very much drawing instrument.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, the utility model comprises compasses and oval assistor, oval assistor comprises rolling bearing 1, rolling bearing 1 is fixed on the top of compasses 2, is fixed with support 3 on the rolling bearing 1, and oval paintbrush 7 is equipped with in activity on the cross bar 4 of support 3, be connected with movable push bar 6 between oval paintbrush 7 and the rolling bearing 1, movable push bar 6 is provided with spring 5, can regulate the position of oval paintbrush 7 like this, thereby determines oval size; Two legs of compasses 2 are provided with fairlead 8; The lower end of oval paintbrush 7 is provided with lead-in wire groove 13; A leg of compasses 2 is provided with movable nib 13, and another leg is provided with lead-in wire and reclaims fixator 10; One end of support is provided with rotary handle 9.
Draw bowlder, syringe needle 11 can be taken off, activity nib 13 is turned to nib down, will go between and 14 take in the leg, get final product the picture standard round by lead-in wire recovery fixator 10.
When drawing ellipse, original compasses are revolved a little 12 by arachnoid to be connected with oval assistor, to go between and 14 reclaim the fixator 10 from lead-in wire and to pull out, the lower end of walking around oval paintbrush 7 is provided with lead-in wire groove 13, connect the fairlead 8 that is provided with another leg, stop 15 by compasses and movable push bar 6 can be determined the draw ellipse of different size of the long and short axle of compasses.
