The invention belongs to the technical field of drawing display, and particularly relates to a display device providing convenience for placing a drawing for mechanical design. For the problem that adrawing display fixing device for mechanical drawing teaching is inconvenient to design and needs to be operated by many people, the following scheme is proposed that the device comprises a placing plate, wherein the outer wall of the top of the placing plate and the outer wall of the bottom of the placing plate are welded with a first connecting transverse plate and a second connecting transverseplate respectively, a first sliding groove is formed in the outer wall of one side of the first connecting transverse plate, the inner walls of the opposite sides of the first sliding groove are welded with a same sliding rod, the outer wall of one side of the sliding rod is slidably connected with a first moving sliding block, the specification of the first moving sliding block is matched with the specification of the first sliding groove, a second sliding groove is formed in the outer wall of one side of the second connecting transverse plate, and the inner wall of one side of the second sliding groove is slidably connected with a second moving sliding block. The display device providing convenience for placing the drawing for the mechanical design not only reduces the labor intensity,prevents the occurrence of wrinkles and breakage from affecting the repeated use of the drawing, but also plays a certain role in protecting the drawing, thereby improving the drawing display effect.
