Abstract
A storable tool used for drawing great circles through a self-chosen pen comprises a supporting part and a circle drawing part. The circle drawing part comprises a fixation clamp and the circle drawing pen, and the circle drawing pen is clamped in the fixation clamp. The storable tool is further provided with a compass frame and a flexible rule. The supporting part comprises a triangular support and a circle center pen which penetrates through the center of the triangular support in the vertical direction. The compass frame is rotationally arranged on the triangular support. The compass frame is provided with a cavity where the flexible rule is wound. One end of the flexible rule penetrates out of the compass frame and is connected with the fixation clamp. The circle drawing radius is determined by adjusting the length of the flexible rule. The storable tool has the beneficial effects that great circles can be accurately and conveniently drawn through the tool used for drawing great circles; due to the arrangement of the triangular support, the problem that serious inclination and unsteadiness occur when great circles are drawn is solved, and great circles are drawn conveniently and steadily; the circle drawing pen can be chosen and replaced by users as needed, so that the storable tool is simple and practical.
Description
Technical field
The present invention relates to a kind of circle tool, specifically a kind of picture received great circle instrument of free pen.
Background technology
The instrument often used when compasses are mappings, the size that circle drawn by common compasses is limited, and be only suitable for student and map uses, and in reality, a lot of design also needs picture circle, and the circle of picture is comparatively greatly, common compasses can not meet; In addition, the pen that circle drawn by compasses is in the market fixing, and usually needs stroke circle that is dissimilar or color during design mapping.
Therefore need to provide a kind of facilitate picture great circle and draw the instrument justified pen and can change.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of picture received great circle instrument of free pen, facilitates picture great circle and draw circle pen to be convenient for changing as required.
The present invention for solving the problems of the technologies described above adopted technical scheme is: a kind of picture received great circle instrument of free pen, comprises support section and draws circular portion, and described picture circular portion comprises geometrical clamp and draws circle pen, draws circle pen and is stuck in geometrical clamp; Also be provided with compass shelf and tape measure, described support section comprises A-frame and the vertical direction center of circle pen through A-frame center; Compass shelf rotates and is arranged on A-frame, described compass shelf is provided with the cavity for being wound around tape measure, one end of tape measure passes compass shelf and is connected with geometrical clamp, picture radius of a circle is determined by the length adjusting tape measure, the outside of described compass shelf is provided with buckle, is limited the relative movement of tape measure and compass shelf by buckle.
The center of circle of the present invention pen is scalable, presses down and can draw the center of circle.
Picture circle pen of the present invention can be changed as required.
Tape measure of the present invention is steel tape.
The invention has the beneficial effects as follows: picture great circle instrument provided by the invention, arranges steel tape and measure picture radius of circle, accurately and picture great circle can be facilitated; Arrange A-frame, avoid tilting during picture great circle serious problem of drawing great circle instability, picture great circle is convenient stable; Center of circle pen is scalable, needs to press the center of circle pen during center of circle, can draw the centered great circle of band; Draw circle pen to be fixed by geometrical clamp, can free replacing as required, simple and practical; Compass shelf be provided be buckled in determine large radius of circle after fix tape measure, avoid picture bowlder radius change draw circle non-type problem.

Mark in figure: 1, A-frame, 2, buckle, 3, center of circle pen, 4, compass shelf, 5, tape measure, 6, draw circle pen, 7, geometrical clamp.
Detailed description of the invention
As shown in the figure, a kind of picture received great circle instrument of free pen, comprises support section and draws circular portion, and described picture circular portion comprises geometrical clamp 7 and draws circle pen 6, draws circle pen 6 and is stuck in geometrical clamp 7; Also be provided with compass shelf 4 and tape measure 5, described support section comprises A-frame 1 and the vertical direction center of circle pen 3 through A-frame 1 center; Compass shelf 4 rotates and is arranged on A-frame 1, described compass shelf 4 is provided with the cavity for being wound around tape measure 5, one end of tape measure 5 passes compass shelf 4 and is connected with geometrical clamp 7, picture radius of a circle is determined by the length adjusting tape measure 5, the outside of described compass shelf 4 is provided with buckle 2, is limited the relative movement of tape measure 5 and compass shelf 4 by buckle 2.
Center of circle pen 3 is scalable, presses down and can draw the center of circle.
Draw circle pen 6 can change as required.
Tape measure 5 is steel tape.
When drawing great circle, A-frame 1 is placed on picture disk, the if desired center of circle, the stroke center of circle, the center of circle can be pressed, then from compass shelf 4, extract tape measure 5 out, measure the radius of circle of needs according to scale, then pressing buckle 2, after fixing tape measure 5, namely drawing circle by drawing round pen 6.
Need change dissimilar or color time, open geometrical clamp 7, change the picture circle pen needed, and then fixing geometrical clamp 7, can picture circle.
At the end of drawing circle, unclamp buckle 2, make tape measure 5 shrink back original position.
