Abstract
The utility model relates to a multifunctional ruler for the students. The utility model comprises a ruler, a set square, a protractor, card marking holes, geometrical holes, and small circular holes, wherein, four small circular holes with different sizes, the geometrical holes and template holes for marking answer sheets are included in the ruler, the middle of one side of the ruler is marked with 0, scales 0 to 8 are extended towards the both sides, and the other side of the ruler is closely connected with the set square arranged outside and the protractor arranged inside, to form a whole body. Based on that the ruler, the set square, and the protractor are combined into a whole, the multifunctional ruler not only can be used for drawing straight lines, but also can be used for drawing semi circles and circles with different sizes, simultaneously has the functions of set square, protractor and compasses, and has the advantages that the structure is simple, the carrying is convenient, the operation is reliable, and the practicability is high, etc.
Description
Technical field
The utility model relates to a kind of chi, and exactly, it is that a kind of student uses multi-functional ruler, belongs to the cultural tools field.
