Description
Technical field
The utility model relates to stationery, in particular to a kind of cyclograph.
Background technique
When drawing circle with traditional compasses, ruler is needed to cooperate the radius for determining circle, operates more troublesome, the center of circle
Position may also break a duck eye.The stabilization of center of circle stitch is difficult to hold during drawing circle.When drawing fan-shaped with traditional compasses
It waits, not only to there is ruler cooperation to determine the length of radius, it is also necessary to which protractor, which cooperates, determines angle, gestures circle and more bothers, more
Kind tool can also be such that user is nervously fumbled.
Summary of the invention
The purpose of the utility model is to provide a kind of circle that can easily draw very much known radius and known radius and angles
The fan-shaped cyclograph of degree.
To achieve the above object, the technical solution of the utility model is:
A kind of cyclograph, the rocker arm including rectangular configuration, one end of the rocker arm are provided with through-hole, the rocker arm upper surface
It is provided with graduation mark, the starting point of the graduation mark is arranged at the center of the through-hole, it is additionally provided with sliding slot on the rocker arm,
The long side of the sliding slot is parallel with the graduation mark, is provided with clamping device on the sliding slot, the clamping device include sleeve,
Nut and screw, the lower cartridge and the nut thread cooperate, and sleeve upper end side is provided with threaded hole, the spiral shell
Pit and the screw thread cooperate, and the through-hole covers on pedestal, and the rocker arm can be around the base rotation, the pedestal
Upper surface be provided with 360 ° of angle index lines.
The rocker arm upper surface is provided with index line, and the index line is directed toward at the center of the through-hole, the index line
The straight line at place intersects with the sleeve axis.
Location hole is provided on the pedestal, the location hole and the through-hole are concentric.
The beneficial effects of the utility model are:
1. rocker arm is covered on pedestal by through-hole, and the rocker arm can very easily be drawn around the base rotation
It is round and pin hole will not be left on drawing.
2. being provided with graduated scale on rocker arm, clamping device can move along the chute, can very easily draw known radius
Circle.
3. base upper surface is provided with 360 ° of angle index lines, the sector of known angle can be very easily drawn.
4. being provided with location hole at base center, the position in the center of circle can be very easily determined.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 is the schematic cross-sectional view of Fig. 1;
Fig. 3 is partial enlargement structural representation at A in Fig. 2;
Fig. 4 is partial enlargement structural representation at B in Fig. 2.
Specific embodiment
One end of -3 cyclograph shown referring to Fig.1, the rocker arm 2 including rectangular configuration, the rocker arm 2 is provided with through-hole
21,2 upper surface of rocker arm is provided with graduation mark 22, and the center of the through-hole 21 is arranged in the starting point of the graduation mark 22
Locate, is additionally provided with sliding slot 23 on the rocker arm 2, the long side of the sliding slot 23 is parallel with the graduation mark 22, on the sliding slot 23
It is provided with clamping device, the clamping device includes sleeve 3, nut 31 and screw 32,3 lower part of sleeve and the nut 31
It is threadedly engaged, the 3 upper end side of sleeve is provided with threaded hole 33, and the threaded hole 33 is threadedly engaged with the screw 32, institute
21 sets of through-hole are stated on pedestal 1, the rocker arm 2 can be rotated around the pedestal 1, and the upper surface of the pedestal 1 is provided with 360 °
Angle index line 12.The rocker arm upper surface is provided with index line 24, and the index line 24 is directed toward at the center of the through-hole 21, institute
Straight line where stating index line 24 intersects with the axis of the sleeve 3.Location hole 11, the positioning are provided on the pedestal 1
Hole 11 and the through-hole 21 are concentric.
When work, pencil is put into sleeve, good position is adjusted, tightens screw, keeps pencil fixed in sleeve, no longer on
Lower movement, then turns nut, keeps clamping device fixed on rocker arm, is not moving along the chute, rocker arm is then being rotated, according to finger
Angle index line indicated by timberline can draw the circle or circular arc of known radius and angle.
