Description
Technical field
The present invention relates to the drawing compass of mathematics drawing instrument technical field, specially tape measure shape.
Background technology
Traditional instrument draws bowlder, uses compasses, and when accurately round radius is drawn, compasses do not reach expected
Effect, in order to overcome this technical problem, has designed and produced the drawing compass of tape measure shape.
The content of the invention
, can be accurately according to circle the present invention provides the drawing compass of tape measure shape for overcome the deficiencies in the prior art
Radius circle is drawn on blackboard.
The technical solution adopted by the present invention to solve the technical problems is：By 1, disk, 2, rotation handle, 3, positioning lock,
4th, circular cotton rope, 5, centimeter scale, 6, clamping lock, 7, metal ring, 8, chalk, 9, disk opening, 10, solution lock-switch, 11, disk
Bearing and 12, cone-shaped nail composition.
The drawing compass of the tape measure shape, it is characterized in that：The inside of disk 1 is provided with disk bearing 11, disc shaft
Hold and circular cotton rope 4 is connected on 11, the center of circle of disk 1 is provided with rotation handle 2 and cone-shaped nail 12, on circular cotton rope 4, makes
There is centimeter scale 5, the installation rotation handle 2 on the bearing bore diameter of disk bearing 11, the lower end of rotation handle 2 connects with cone-shaped nail 12
It is connected together.
The drawing compass of the tape measure shape, it is characterized in that：Being made on disk 1 has disk opening 9, disk opening 9
Making above has positioning lock 3 to conciliate lock-switch 10.
The drawing compass of the tape measure shape, it is characterized in that:Metal ring 10 is connected on circular cotton rope 4, round metal
The internal diameter of ring 10 is identical with the cross-sectional diameter of chalk, and chalk 8 is installed on the inside of metal ring 10, is made on metal ring 10
There are clamping lock 6, the chalk 8 of the inside of fixed metal ring 10.
The beneficial effects of the invention are as follows：The drawing compass of tape measure shape, drafting circle is convenient and efficient in teaching, is convenient for carrying.
Therefore the invention has the advantages that：This product makes simple, easily promotion and popularization.
