The utility model provides a pair of compasses through adopting foretell structure, utilizes can the draw up circle of different diameter of two pens, the people was stabbed easily to the tiptoe end that can avoid current compasses effectively problem, and simultaneously, it also possesses the ruler function, makes compasses and ruler mapping in coordination, changes mapping instrument, simple structure, convenient and practical during avoiding mapping frequently.

Description

A kind of compasses
Technical field
The utility model relates to study article field, particularly a kind of compasses.
Background technology
In study and work, often can meet the situation that mapping worked in coordination with by compasses and ruler, due to existing drawing tool function singleness, need to change drawing tool continually, and existing compasses be bifoot type, it is most advanced and sophisticated easily pricks people, is inconvenient to use.For addressing this problem, provide a kind of compasses.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of compasses, utilize two pens can draw the circle of different-diameter, the toe end of existing compasses can be effectively avoided easily to stab the problem of people, simultaneously, it also possesses ruler functions, makes compasses and the collaborative mapping of ruler, changes drawing tool continually during avoiding mapping, structure is simple, convenient and practical.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of compasses, comprise slide bar and slide block, described slide block is connected by chute with slide bar, described slide bar one end is provided with protractor and erasing rubber, and described protractor circle centre position is provided with circle center hole, is provided with aperture in the middle of described slide block, the edge of described slide bar is provided with graduation mark, and the line of described circle center hole and aperture is parallel to the limit of slide bar.
A kind of compasses that the utility model provides, by adopting above-mentioned structure, during use, the nib of one-pen is fixed on circle center hole as the center of circle, the nib of another one-pen, to correct position, is placed in the aperture on slide block, and rotates by moving slider, can draw the circle of specific size, and diameter can be controlled by the position changing slide block.Can effectively avoid the toe end of existing compasses easily to stab the problem of people like this, meanwhile, it also possesses ruler functions, and make compasses and the collaborative mapping of ruler, change drawing tool continually during avoiding mapping, structure is simple, convenient and practical.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure: slide block 1, slide bar 2, protractor 3, erasing rubber 4, aperture 5, circle center hole 6.
Detailed description of the invention
As in Fig. 1, a kind of compasses, comprise slide bar 2 and slide block 1, described slide block 1 is connected by chute with slide bar 2, and described slide bar 2 one end is provided with protractor 3 and erasing rubber 4, and described protractor 3 circle centre position is provided with circle center hole 6, be provided with aperture 5 in the middle of described slide block 1, the edge of described slide bar 2 is provided with graduation mark.Structure thus, during use, the nib of one-pen is fixed on circle center hole as the center of circle, moving slider is to correct position, the nib of another one-pen is placed in the aperture on slide block, and rotate, the circle of specific size can be drawn, and diameter can be controlled by the position changing slide block.Can effectively avoid the toe end of existing compasses easily to stab the problem of people like this, meanwhile, it also possesses ruler functions, and make compasses and the collaborative mapping of ruler, change drawing tool continually during avoiding mapping, structure is simple, convenient and practical.
Described circle center hole 6 and the line of aperture 5 are parallel to the limit of slide bar 2.Structure thus, can control drawn radius of a circle size easily.
The above embodiments are only optimal technical scheme of the present utility model; and should not be considered as restriction of the present utility model; the technical scheme that protection domain of the present utility model should be recorded with claim, the equivalents comprising technical characteristic in the technical scheme of claim record is protection domain.Namely the equivalent replacement within the scope of this improves, also within protection domain of the present utility model.
