Connection inside two elements.For the ordinary skill in the art, above-mentioned term can be understood at this with concrete condition
Concrete meaning in invention.
With reference to figure 1, the present embodiment provides a kind of compasses, including:Dial disc 1 and supporting rod 2, dial disc 1 are hollow
Cylinder, dial disc 1 circumferentially be equipped with angle line, angle line from 0 to 360 degree, and the upper surface edge of dial disc 1 with
And side is designed with identical angle line, convenient for the central angle and radian value of circular arc after observation mapping, wherein radian value can be by justifying
It converts to obtain in heart angle;Supporting rod 2 is equipped with graduation mark along the axis direction of bar, and graduation mark is using the center of supporting rod 2 as scale
Zero, graduation mark mark are located at the edge of supporting rod 2, and the graduation mark on supporting rod 2 is used to read the radius of drawn circle.Supporting rod 2
Both ends make it is tapered, facilitate read dial disc 1 on angle value.
With reference to figure 2, dial disc 1 circumferentially sets also sliding rail 3, and sliding rail 3 is that round and its diameter is slightly less than dial disc
Outer diameter, sliding rail 3 are the groove body that bottom is wide, top is narrow, and the both ends of supporting rod 1 are stuck in sliding rail 3, make supporting rod 1 on sliding rail 3
Rotation.Specifically, the both ends of supporting rod 1 are equipped with idler wheel 4, and idler wheel 4 is connect with supporting rod 1 by straight-bar 5, and idler wheel 4, which is located at, to be slided
The bottom of rail 3 is equivalent to the inside that idler wheel 4 is stuck in sliding rail 3, the compasses sound construction that designs in this way, stabilization, and when mapping is not easy to take off
Leave the right or normal track mark, and the height of straight-bar 5, which is just contacted with the upper surface of dial disc 1 with to meet supporting rod 2, to be advisable, and angle line is located at support
So that it is convenient to angle value when supporting rod 2 rotates on reading angular line on the outside of the end of bar 2, to quickly know drawn circle or
The central angle and radian value of circular arc need not be measured additionally using survey tools such as protractors, very convenient.
In order to realize the label in the center of circle, with reference to 1 and Fig. 3, it is equipped with second in the centre position of supporting rod 2 and fixes the pen cap 6, by
It is overlapped with the diametric(al) of dial disc 1 in 2 axis of supporting rod, second fixes that the pen cap 6 is vertical with supporting rod 2 and and dial disc
1 is coaxial, and the second side for fixing the pen cap 6 is equipped with the second lock-screw 7.It is fixed second and is inserted into marker pen 8 in the pen cap 6, and led to
It crosses the second lock screw to be fixed, when installation makes the pen container bottom of marker pen 8 be in same flat with the lower surface of dial disc 1
Face.Marker pen 8 uses the telescopic marker pen of pen core, and the flexible of pen core can be realized in the pen cap by pressing 8 top of marker pen,
When needing to mark the center of circle, the pen core of marker pen 8 need to be only pressed, and pen core can retract in pen container after label.
The picture pen 9 that can be slided along supporting rod 2 is additionally provided on supporting rod 2, gel ink pen or hard can be used in picture pen 9
Pencil, picture pen 9 are arranged in parallel with marker pen 8.Adjust position of the picture pen 9 on supporting rod 2, rotary supporting rod 2, picture pen
9 can draw circle or circular arc, and circle can be read by reading the distance between picture pen 9 and marker pen 8 by the scale on supporting rod 2
Or the radius of circular arc, while corresponding angle value is directly read by the graduation mark on dial disc 1, and then learn its radian
Value.
