Abstract
The utility model relates to a magnetic absorption type compasses comprising a compasses body. The compasses body is connected with a first compasses support leg and a second compasses support leg, the first compasses support leg is connected with a magnet, and the second compasses support leg is connected with a piece of chalk. When the magnetic absorption type compasses is used for drawing a circle, the compasses can be fixed on a blackboard firmly by the magnet so as to draw a circle, so that the compasses can not be easy to fall off from the blackboard, and can not damage the blackboard.
