Abstract
The invention provides multi-functional compasses. According to the multi-functional compasses, an angle gauge is arranged on a connection position of two supporting legs, a distance adjustment ruler is arranged between the two supporting legs respectively through a hinged shaft and an adjusting screw column, when the multi-functional compasses are used, through the distance adjustment ruler between the two supporting legs, the two supporting legs are enabled to fixedly draw a round shape, further, a usage angle of the angle gauge can be accurately adjusted, and the multi-functional compasses are enabled to be more convenient and adequate to use.
Description
Technical field
The present invention relates to a kind of compasses, specifically a kind of multifunctional compass.
Background technology
Common compasses can only use as drawing circular diagram, in use, can only use the fixed axis of two supporting legs to regulate, and will cause slightly because of carelessness two distances between supporting leg to make a fault, directly the accuracy of impact picture.
Summary of the invention
The invention provides a kind of multifunctional compass, in the time of can allowing drawing, the adjusting of two supporting legs can be fixed, and can grasp accurately and calculate angle.
The present invention includes the supporting leg of compasses, the technical scheme that adopts is: described compasses are equipped with a protractor at the connecting place of two supporting legs, by hinge and adjusting double-screw bolt, the spacing adjustable ruler are installed respectively between two supporting legs.
Beneficial effect of the present invention is: during use, can allow two supporting legs fixedly draw circle by the spacing adjustable ruler between two supporting legs, also the use angle of adjustment amount hornwork accurately, allow compasses use convenient and to prepare.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Accompanying drawing is structural representation of the present invention.
The specific embodiment
Shown in accompanying drawing embodiment: compasses are equipped with between 2, two supporting legs 1 of a protractor respectively by hinge 4 and regulate double-screw bolt 5 at the connecting place of two supporting legs 1 spacing adjustable ruler 3 is installed.
Claims (1)
1. multifunctional compass, the supporting leg (1) that comprises compasses, it is characterized in that: described compasses are equipped with a protractor (2) at the connecting place of two supporting legs (1), by hinge (4) and adjusting double-screw bolt (5), spacing adjustable ruler (3) are installed respectively between two supporting legs (1).
