Zusammenfassung: | The utility model discloses a flexible rule, which comprises a reel and a rule. A location hole is arranged between each two centimeter scales. When the flexible rule is used, the rule is pulled out from the reel; when a straight line needs to be drawn, the straight line is measured and drawn directly by using the rule; and when a circle needs to be drawn, a pen point is fixed on the location hole at the corresponding position, then, the reel is held with one hand, and the rule is rotated by utilizing a pen with another hand, and therefore, the problem that only the circle can be drawn by using the rule and compasses simultaneously is solved. The flexible rule is more convenient to use. |
