Abstract
The utility model discloses a kind of compasses of amount diameter.Existing compasses, general needs carrys out picture circle by ruler, and this makes troubles to drawing.The utility model provides a kind of compasses of amount diameter, carries scale, can measure diameter of a circle voluntarily, draw circle fast.Technical scheme is: a compass foot of the utility model compasses body is equipped with scale.Bulb is equipped with in one end of scale.Scale is enclosed within slide block, and scale can along skid.Scale is carved with scale, diameter of a circle drawn by compasses can be determined.Slide block and compass foot chain connection, slide block can rotate around compass foot.Another compass foot of compasses body is done have ball-type to cheat.During use, the bulb of scale one end is stuck in ball-type hole, pulls two compass foots, and scale can slide by opposing slider, and diameter of a circle drawn by scale determination compasses, can draw circle fast.During collection, scale can go to the position overlapped with compass foot, reduces storage area.
Description
Technical field:
The utility model relates to a kind of compasses, specifically, especially relates to a kind of compasses of amount diameter.
Background technology:
Existing compasses, general needs carrys out picture circle by ruler, and this makes troubles to drawing.
Summary of the invention:
The purpose of this utility model is to provide a kind of compasses of amount diameter, carries scale, can measure diameter of a circle voluntarily, draw circle fast.
In order to achieve the above object, the technical solution of the utility model is: a kind of compasses of amount diameter are made up of compasses body, bulb, ball-type hole, compass foot, scale, scale, slide block, hinge etc.
A compass foot of the utility model compasses body is equipped with scale.Bulb is equipped with in one end of scale.Scale is enclosed within slide block, and scale can along skid.Scale is carved with scale, diameter of a circle drawn by compasses can be determined.Slide block and compass foot chain connection, slide block can rotate around compass foot.Another compass foot of compasses body is done have ball-type to cheat.During use, the bulb of scale one end is stuck in ball-type hole, pulls two compass foots, and scale can slide by opposing slider, and diameter of a circle drawn by scale determination compasses, can draw circle fast.During collection, scale can go to the position overlapped with compass foot, reduces storage area.
The beneficial effects of the utility model are: a kind of compasses of amount diameter, carry scale, can measure diameter of a circle voluntarily, draw circle fast.
Accompanying drawing illustrates:
Fig. 1 is scale operating position of the present utility model schematic diagram.
Fig. 2 is scale expanded position schematic diagram of the present utility model.
Fig. 3 is scale favorite places schematic diagram of the present utility model.
In above-mentioned accompanying drawing, the meaning of each numbering is: 1: compasses body; 2: bulb; 3: ball-type is cheated; 4: compass foot; 5: scale; 6: scale; 7: slide block; 8: hinge.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is further described.
Refer to Fig. 1 ~ Fig. 3: a kind of compasses of amount diameter, comprise compasses body (1), bulb (2), ball-type hole (3), compass foot (4), scale (5), scale (6), slide block (7), hinge (8).
A compass foot (4) of the utility model compasses body (1) is equipped with scale (5).Bulb (2) is equipped with in one end of scale (5).Scale (5) is enclosed within slide block (7), and scale (5) can slide along slide block (7).Scale (5) is carved with scale (6), diameter of a circle drawn by compasses can be determined.Slide block (7) is connected with compass foot (4) hinge (8), and slide block (7) can rotate around compass foot (4).The upper work of another compass foot (4) of compasses body (1) has ball-type to cheat (3).
During use, it is inner that the bulb (2) of scale (5) one end is stuck in ball-type hole (3), pull two compass foots (4), scale (5) can slide by opposing slider (7), diameter of a circle drawn by compasses can be determined according to scale (6), draw circle fast.During collection, scale (5) can go to the position overlapped with compass foot (4), reduces storage area.
