Abstract

The utility model relates to a multifunctional T square which is provided with a fixed ruler, a main ruler, an angle measuring slide block and a movable ruler, wherein, the fixed ruler and the main ruler are hinged by a revolving pair and fixed by screws; the main ruler and the angle measuring slide block are connected by a moving pair; the angle measuring slide block and the movable ruler are hinged by a revolving pair and fixed by screws. The movable ruler is provided with a plurality of rectangular through grooves which are parallel with each other with the same groove distance and the same groove width. The utility model is able to measure a variety of section lines with any angle and distance (the section picture of engineering). The existing T square can be sheathed on the angle measuring slide block connected with the movable ruler without changing so as to have the various functions of the multifunctional T square. The multifunctional T square has the advantages of complete function, easy manufacture and high application capacity.
