Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example one

Referring to fig. 1-4, a multifunctional ruler specially used in the engineering technical field comprises a first main ruler 1, a second main ruler 2 and a scale 3, wherein the first main ruler 1 and the second main ruler 2 are both fixedly connected with a fixed shaft 4, one end of the fixed shaft 4 is both fixedly connected with a scale 5, two fixed shafts 4 are sleeved with connecting rulers 6, two corners of one side of the first main ruler 1 are both movably connected with connecting buckles 7, two corners of one side of the second main ruler 2 are both provided with connecting blocks 8, the first main ruler 1 and the second main ruler 2 are movably connected through the connecting rulers 6, the first main ruler 1 and the second main ruler 2 are both provided with the scale 3, the connecting rulers 6 can respectively rotate on the first main ruler 1 and the second main ruler 2 through the two fixed shafts 4, the two scales 5 are respectively fixedly connected with the first main ruler 1 and the second main ruler 2 through the fixed shafts 4, the surfaces of the scale 5 are provided with angles, the contained angle between 6 and first main scale 1 or the second main scale 2 of connecting chi can be measured to calibrated
