Abstract:
     The present invention relates to an U-shaped multifunctional adjustable rule. It is composed of a main rule, two adjustable rules and a card. When one adjustable rule in main rule is pushed out from one end of the main rule and rotated upwards at 90 deg., it can be made into a T-squane. Another ajustable rule also can be pushed out or fully drawn out from another end of the main rule or connected with the former end to form a set square. Besides, two protractor holes with a properly large radius are opened in both sides of the main rule to form the angle-measuring scales for teaching and general purposes respectively.
