[0034] like Figure 1-6 As shown, during the use of the road bridge design drawing winding device, one end of the drawing is first inserted into the inner side of the drawing clamping plate 43, and then the winding roller 4 is positioned by rotating the bracket 67, and the sliding column 41 is pushed to slide, so that the pulling rod 44 pulls the C-shaped clamping plate 45 to clamp and fix the drawing. Then, the winding motor 3 is started, driving the winding roller 4 to rotate, and performing the winding work of the road bridge design drawing. Under the action of the tightening spring 53, the pressure roller 5 applies pressure to the drawing on the winding roller 4 to ensure that the drawing is stably wound on the winding roller 4.
