Summary:The utility model belongs to a drawing tool, particularly an angle divider which can freely equally divide an angle. The utility model comprises a straight line side of a ruler and a moving circle which can roll along the straight line side. An initial definition line is arranged at the edge of the moving circle; an initial alignment line is arranged on a straight line side of one end of the ruler so as to determine the initial position of the moving circle; a handle is arranged at the center of circle of the moving circle; an indicating pointer is fixedly connected with the handle; the handle movably fits with the moving circle, which is convenient for an operator to push the edge of the moving circle to roll along the straight line side after pinching the handle by a hand; the included angle between the position pointed by the indicating pointer and the initial definition line is the angle to be equally divided.
