Abstract
The invention provides a compass, wherein a radius-adjustable graduated scale is arranged between two compass rods of the compass; one of the two compass rods is connected with one end of the graduated scale through a hinge shaft; and the other of the two compass rods is arranged in a sliding chute of the graduated scale through an adjustable bolt. When the compass is in use, the pitch between the two compass rods on the graduated scale can be adjusted through adjusting tension of the bolt, so that a radius required for drawing a circle is obtained; moreover, the compass provided by the invention has the effects of convenience and rapidness for using the compass.
Description
Technical field
The present invention relates to a kind of compasses, a kind of specifically compasses with rule.
Background technology
Compasses are to draw one of employed instrument of circle in the working and learning, and traditional compasses will adopt ruler to mark the required radius of picture circle earlier in use, then could be with the compasses required figure that draws, and both inconvenient in the use, also influence the speed of working and learning.
Summary of the invention
The present invention provides a kind of compasses, can pass through with rule directly regulate radius distance, pictorial pattern fast, easily draws.
The present invention includes the gauge bar of compasses, the technical scheme that is adopted is: said compasses are equipped with the rule of a scalable radius between two gauge bars.
Two gauge bars of said compasses one of them adopt hinge to be connected a termination of rule, and another gauge bar is installed in the chute of rule through adjustable bolt.
Beneficial effect of the present invention is: during use, can regulate the spacing on rule between two gauge bars through the degree of tightness of regulating bolt, can obtain the required radius of picture circle thus, have the effect of using compasses easily and fast.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is made further detailed description.
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
Shown in the accompanying drawing embodiment: compasses are equipped with the rule 2 of a scalable radius between two gauge bars 1.Two gauge bars, 1 one of them employing hinge 3 of compasses is connected a termination of rule 2, and another gauge bar 1 is installed in the chute 5 of rule 2 through adjustable bolt 4.
Claims (2)
1. compasses comprise the gauge bar (1) of compasses, and it is characterized in that: said compasses are equipped with the rule (2) of a scalable radius between two gauge bars (1).
2. a kind of compasses according to claim 1; It is characterized in that: two gauge bars (1) of said compasses one of them adopt hinge (3) to be connected a termination of rule (2), and another gauge bar (1) is installed in the chute (5) of rule (2) through adjustable bolt (4).
