Abstract
The utility model relates to a multifunctional teaching ruler which comprises a protractor and a straight ruler connected with the protractor. One end of the straight ruler is hinged to the center of the straight side of the protractor, and a sucker used for fixing the protractor is arranged on the back of the protractor. The teaching ruler is formed by hinging the protractor to the straight ruler. When the teaching ruler is used, functions of the protractor and the straight ruler can be achieved, and the protractor and the straight ruler can be matched to achieve functions of a set square. The teaching ruler has the advantages of being full in function, simple in structure and convenient to use and carry. In addition, the sucker is arranged on the back of the protractor. When the teaching ruler is used, the protractor is sucked on a backboard through the sucker, the problems of low accuracy and labor waste due to the fact that a teacher needs to press the protractor while conducting drawing are solved, work load of the teacher is reduced, and drawing efficiency and teaching progress are improved.
