Description
Technical field
The present invention relates to a kind of convenient drawing instrument field, and in particular to a kind of ellipsograph.
Background technology
In middle and primary schools of today teaching classroom, it is lead-pipe cinch to draw a circle by compasses, but to make a size
The suitable accurate ellipse of eccentricity is extremely inconvenient.Common ellipsograph is by the base plate and swing arm group that have cross chute
Into, it is a kind of oval light instrument of ancient drawing, relatively more inflexible, it is unpractical to enter into student classroom.At present more
Advanced ellipsograph is a kind of magnetic, has the ruler with dead slot, two magnetic to slide focus part etc. and constitute magnetic slip focus
On ruler, adjustable focal length is inhaled on blackboard, and the line of closure is enclosed within slip focus draws oval.It can not serve
It is raw.According to it is currently understood that the ellipsograph for arriving, goes back picture the Ellipse tool that the more suitable student of neither one is applicable both at home and abroad.Therefore,
A kind of simple to operate, function admirable, practical ellipsograph is urgently researched and solved.
The content of the invention
For shortcomings and deficiencies present in above-mentioned technology, present invention aim at a kind of ellipsograph of offer, the device energy
It is enough to realize that picture be facilitated oval, stroke circle can be also pressed from both sides, can also press from both sides the convenient effect that graver cuts out circle.
Realizing the technical scheme that foregoing invention purpose is used is：A kind of ellipsograph, mainly including connecting rod, left support arm, the right side
Support arm, screw rod, left burnt pin, right burnt pin and tape, the ellipsograph is by the connection of connecting rod top left support arm and right support arm, two support arms
Middle part extends transversely through two screw rods, and two support arm lowermost ends respectively set left burnt pin and right burnt pin；Described left support arm upper end
The handle of longitudinal direction is set；The lower section side of the right support arm sets card groove, by the spacing ring of semicircle shape and through card pen thereon
Device is limited, it is characterised in that described two screw rods middle part respectively sets a handwheel, and intermeshing can drive screw rod to adjust two
Arm room is away from making two support arms to move in parallel；Described left burnt pin top front face runs through the one number service hole for penetrating tape together；Institute
The one number service hole side stated sets left control button, and the back side of through hole sets the tape box for shrinking；The top of described right burnt pin
Longitudinally disposed No. two through holes, the latch of tape termination connection is inserted in No. two through holes, and the right control button set by side is controlled
Plug；Described tape directly gives picture radius of circle.
The side of described connecting rod is rotatably connected place, and dead angle circular arc joint is not stayed in setting；Connecting rod and left support arm and right branch
The connection of arm, work is not limited treatment by angle.
Described latch is at zero graduation line with tape junction.
The length of described screw rod is combined according to the length of connecting rod and tape and set.
The screw thread set on described connecting rod or so rotation direction is conversely, oppositely oriented up and down.
Described left control button is tossed about setting spring, belongs to pressing unblocked type button；Described right control button belongs to
Insert resistance type button.
Described one number service hole and No. two aperture positions of through hole are in same horizontal line, and with corresponding burnt pin
At tip on same longitudinal axis, i.e., burnt pin is set to semi-conical.
Described burnt pin should be short and small, shortens the distance on tape defocus pin top, reduces the oval error of gained.
Graver as shown in Figure 5, to be made up of a body and cutter head can be fixed in a described card groove, for cutting out circle.
Described left support arm and right support arm can be cylindrical, or stupefied cylindricality.
The beneficial effects of the invention are as follows, this colony of student is had finally and make oval instrument conveniently, can random root
According to required size, required eccentricity is drawn oval.Also can be used to any picture within books to justify, more conveniently, drawing bowlder can root
According to flexible rule scales, round radius is given.Big cabinet also dependent on the required round scraps of paper justifies the scraps of paper.

Specific embodiment
The specific embodiment for being given with inventor with reference to the accompanying drawings, further retouches to a kind of ellipsograph of the invention
State：
Fig. 1 gives the structural representation of ellipsograph of the present invention, and the left Jiao Jiaochu that Fig. 2 gives ellipsograph of the present invention amplifies signal
Figure, Fig. 3 gives enlarged diagram at the right burnt pin of ellipsograph of the present invention, and the left burnt pin that Fig. 4 gives ellipsograph of the present invention is left
View, when drawing oval, first pulls out tape 11 from the end of left control button 8, the control that latch 16 is passed through right control button 13, inserts
In No. two through holes 17 of the upside of right burnt pin 18, according to the length of required oval big tape 11 good in a small amount, then adjust handwheel 6 and determine
Distance and left burnt pin 7, the position of right burnt pin 18 of left support arm 2 and right support arm 3, a hand are fixed on handle 4, and another hand is taken
Drawing pen is close to tape 11 and draws a semiellipse arc, the position of left burnt pin 7 and right burnt pin 18 is exchanged afterwards, in the semiellipse finished
Ibid method draws another semiellipse arc to the plane of symmetry of arc；
Bowlder is drawn, drawing pen is put into card groove 12, fixed by card groove 12 and spacing ring 14, hand catches handle 4 and draws circle
Arc, right burnt pin 18 herein should be higher than that drawing pen nib, and tape measure 11 can provide the radius of required circle with direct measurement, convenient fast
It is prompt.
Fig. 4 gives the accessory graver schematic diagram of ellipsograph of the present invention, cuts out bowlder.Drawing pen is changed to graver, and it is fixed
In card groove 12, fixed with spacing ring 14, cut out circle method with picture circle method.
