A multifunctional compass

Abstract

The invention discloses a multifunctional compasses. The multifunctional compasses comprises a first compasses arm, a second compasses arm, a flexible display, an angle sensor and a controller, wherein a first end of the flexible display winds around the surface of the first compasses arm, a second end of the flexible display is connected to the second compasses arm; the first end is opposite to the second end; the angle sensor detects the angle between the first compasses arm and the second compasses arm; the controller is respectively connected to the angle sensor and the flexible display, the controller controls the flexible display to display information related to the angleaccording to the angle detected by the angle sensor and a pre-stored length of the first compasses arm / second compasses arm, and controls the flexible display winding around the surface of the first compasses arm to display a scale line simultaneously, so that the multifunctional compasses can be used as a compasses and can be used as a ruler and a protractor simultaneously, and a drawing tool such as a ruler and a protractor does not need to be used, thereby simplifying the drawing steps and improving the drawing efficiency.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a multifunctional compass. Background technique [0002] In the process of drawing, it is often used for drawing tools such as compasses, rulers, and protractors. For example, compasses are used to draw arcs, circles, etc.; rulers are used to measure the radius of circles, lengths of straight lines, etc.; protractors are used to measure angles. When using a compass to draw a sector diagram, first, you need to use a straightedge to measure the radius of the sector, use a protractor to measure the included angle of the sector, and then use a compass to draw an arc with the measured radius as the radius. Therefore, when using compasses to draw graphics, it is necessary to switch to other tools at any time, resulting in cumbersome drawing steps and low drawing efficiency.
