Abstract

A combined ruler convenient to use comprises an angle gauge, wherein the angle gauge is provided with a central point, one side of the angle gauge is fixedly connected with a straight scale, the straight scale is provided with a scale line, the other end of the straight scale is connected with a compasses tip, the central point of the angle gauge is relatively and rotatably connected with a rotating shaft, the other end of the rotating shaft is connected with a pen container, a through hole is formed in the rotating shaft, and the formation position of the through hole corresponds to the scale line on the angle gauge. The combined ruler integrates the angle gauge, compasses and the straight scale, and greatly facilitates carrying and using for teachers.
