Zusammenfassung:	The utility model relates to a ruler for students, which is used by students to draw parallel lines, in particular to a fixed ruler formed by a plane frame. The surface of the fixed ruler is provided with a movable ruler which has two ends embedded in the two sides of the plane frame and can move up and down translationally. A compass can be arranged on the surface of the fixed ruler. The fixed ruler can be rectangle or square. The surface of the fixed ruler can not be provided with the compass. With the ruler, the students can draw a line parallel to a baseline if provided, no matter at what distance, the tow lines are ensured to be parallel with each other and the grids drawn are uniform and the students also can draw parallel lines along the direction pointed by the compass, which brings great convenience to the students.
