Abstract
The utility model discloses fast-type graduated compasses and solves the problem that circles of needed sizes can not be accurately drawn by the existing compasses is solved. The utility model is characterized in that a scribing branch leg (3) is provided with a soft band (4) with scale marks, and each scale mark corresponding to the distance between the tips of the two branch legs of the compasses is a set fixed value. The fast-type graduated compasses can be widely used for learning and drawing by school students and engineering technical personnel.
Description
One, technical field
The practical study article that belongs to relates in particular to a kind of quick type amount Graduated compasses.
Two, background technology
The compasses that existing market is sold all are to be made of handle, center leg and line leg etc., though relatively simple for structure, in the size that does not have can't know under the situation of ruler drawn circle.
Three, utility model content
Of the present utility model is for people provide a kind of simple in structure, can be according to directly the draw quick type amount Graduated compasses of target sizes circle of people's needs.
Its technical scheme of the present utility model is: it is made up of handle, center leg and line leg etc., is provided with the soft band of band scale mark on the line leg, the fixed value of the corresponding compasses two leg distance between two tips of its each scale for setting.
This reality has novel beneficial effect to be: not only simple in structure, and can know the size of knowing drawn circle, very easy to use.
Four, description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1 is handle, and 2 is the center leg, and 3 are line leg, the 4 soft bands for the band scale mark.
Five, the specific embodiment
As shown in Figure 1, producing on the basis of common compasses, on any of two legs, fixedly installing band the soft of scale mark and be with 4, softly be with that corresponding two tiptoes distance of each scale is 0.5 centimetre or 1 centimetre on 4.When implementing the utility model, only leg 2 tips in center need be put in and draw round center, calculate according to required picture radius of a circle then that soft the leg 3 of will ruling then draws back to this scale mark place with the corresponding scale on 4, rotary handle 1 circle of required size that can draw.
