1results about How to "Drawn precisely" patented technology

This utility model discloses a drawing board for engineering cost estimation, relating to the technical field of engineering cost estimation tools. It includes a first drawing board body, a rotating shaft rotatably connected to one side of the first drawing board body, and a second drawing board body fixedly connected to the other side of the rotating shaft. Assembly blocks are symmetrically fixedly connected to one side of the first drawing board body, and fixing components are installed inside the assembly blocks. L-shaped plates are symmetrically slidably connected to one side of both the first and second drawing board bodies, and clamping components are installed on one side of the L-shaped plates. Merging components are installed on both sides of the first drawing board body. This utility model, using the above structure, folds the originally large board surface into a compact form, easily placing it under a desk, in a closet gap, or in a corner of a vehicle, greatly freeing up office and living space. Moreover, the folded drawing board significantly reduces the difficulty of carrying it; whether going out to survey sites or going to construction sites to coordinate drawings, it can be easily packed into a backpack or handbag, meeting the frequent movement needs of engineering cost estimators.
