| description | The utility model discloses a multifunctional teaching ruler. The multifunctional teaching ruler is characterized by comprising a longest straight ruler, a middle short straight ruler, a shortest straight ruler and a middle long straight ruler which are connected through bolts in sequence; the length of the longest straight ruler is 600 mm, the width of the longest straight ruler is 40 mm, and the thickness of the longest straight ruler is 5 mm; the length of the shortest straight ruler is 120 mm, the width of the shortest straight ruler is 40 mm, and the thickness of the shortest straight ruler is 5 mm; the length of the middle short straight ruler is 300 mm, the width of the middle short straight ruler is 40 mm, and the thickness of the middle short straight ruler is 5 mm; the length of the middle long straight ruler is 420 mm, the width of the middle long straight ruler is 40 mm, and the thickness of the middle long straight ruler is 5 mm. Materials are convenient to get, the multifunctional teaching ruler can be obtained by machining an existing plastic ruler or a stainless steel ruler easily, cost is low, the technology is easy, and using is convenient; on the basis of flexibly applying the planar linkage characteristics, the multifunctional teaching ruler can be used for demonstrating the motion principle of a linkage mechanism and the change process of mechanism types. |
