The invention discloses a protractor capable of measuring a 360 degrees angle. The protractor is composed of a lower protractor body and an upper protractor body, the lower protractor body and upper protractor body are stacked and movably crossed into a single unit, and the lower protractor body and upper protractor body are connected through a pin shaft. When using, any angle within 360 degrees can be measured through the rotation regulation between the lower protractor body and upper protractor body, and the needed angle can be intuitively and precisely measured through a crossed empty angle there-between.
Description
technical field [0001] The invention relates to a protractor, specifically a protractor capable of measuring 360 0 Angle protractor. Background technique [0002] The protractors used now can only measure 180 0 For the single structure of the angle, when measuring and calculating, it is necessary to mark the angle line that should be measured with a pen, and it is impossible to make an intuitive, fast and accurate calculation. Contents of the invention [0003] The present invention provides a measureable 360 0 Protractor for angles, available in 360 0 The angle range can be used to measure and calculate any angle, and it is fast and accurate. [0004] The present invention includes a lower protractor body and an upper protractor body of a protractor. The technical solution adopted is that the protractor is combined with the lower protractor body and the upper protractor body by superimposed movable crossing, and the two are connected by a pin shaft. [0005] The bene...
