A novel engineering drawing board of the utility model can not only fix drawings on the drawing board, but also ensure that the drawings are even and orderly, so that users can draw relatively neat graphics on the engineering drawings, which is convenient for learners to draw. Adding an adjustment frame can make the drawing board suitable for drawings of various sizes, which is convenient and practical.

As a further improvement of the utility model, a fixing clip is also provided above the drawing board body. The fixing clip can fix the upper edge of the drawing, and the combination of the imprint groove and the fixing clip can ensure that the drawing is neat and tidy, so that the user can draw a more neat figure on the engineering drawing, which is convenient for learners to draw, convenient and practical.

The adjustment frame can be set in a U shape, and a compression piece is arranged at two corners of the lower end of each adjustment frame, and one end of the compression piece is rotatably connected to the side of the adjustment frame. The two corners of the lower end of the drawing board body are also respectively provided with pressing pieces, and one end of the pressing piece is rotatably connected to the side of the drawing board body.

The adjustment frame can also be set to be L-shaped, and a compression piece is arranged at a corner of each adjustment frame, and one end of the compression piece is rotatably connected to the side of the adjustment frame. The two corners of the diagonal line of the board body are also respectively provided with pressing pieces, and one end of the pressing pieces is rotatably connected to the side of the drawing board body.

A new type of engineering drawing board of the utility model can well overcome the problems of difficult fixing and unevenness. The imprint groove is formed by stamping, and the engineering drawing is stuck in the imprint groove, which can fix the drawing in the center. In the center of the wooden engineering drawing board body, there is an imprint groove formed by stamping, and the lower two corners or diagonals are pressed. The tight piece is pressed, and the top is clamped by the fixing clip. A novel engineering drawing board of the utility model solves the problems that drawings are difficult to be fixed on the drawing board and cannot ensure that the drawings are even. When in use, as long as the engineering drawing is stuck in the imprint groove, press the drawing with the two corners or diagonal compression pieces at the bottom, and clamp the drawing with the fixing clip at the top, the drawing can be fixed on the drawing board horizontally and evenly superior. The beneficial effect of the utility model is that the drawings can be fixed and aligned to ensure that the drawings are even and orderly, so that users can draw more neat graphics on the engineering drawings, which is convenient for learners to draw.
