[0029] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0030] Embodiment 1:

[0031] Please refer to Figure 1-Figure 3 A drawing display stand includes a base 1, rollers 2 are fixedly connected at the four end corners of the lower end of the base 1, a cavity is opened in the middle of the upper end of the base 1, a rotating component 3 is arranged inside the cavity, a first connecting rod 4 is fixedly connected to the middle of the upper end of the rotating component 3, a display board 5 is fixedly connected to the end of the first connecting rod 4 away from the rotating component 3, and two clamping mechanisms 7 are arranged on the front of the display board 5.

[0032] Through the above structural design, it can be known that the drawings can be clamped on the display board 5 through the cooperation of the clamping mechanism 7 and the first slide groove 6, and the drawings can be displayed through the display board 5. The rotation angle of the display board 5 can be adjusted by the rotating component 3.

[0033] Specifically, the clamping mechanism 7 includes a connecting plate 8, and sliders 9 are fixedly connected to the upper and lower ends of the connecting plate 8 close to the display board 5. First sliding grooves 6 are provided at the upper and lower ends of the front of the display board 5 and at positions corresponding to the sliders 9. The sliders 9 at the same end are slidably connected to the first sliding grooves 6 at the same end. A clamping assembly 10 is provided on the side of the connecting plate 8 close to the display board 5 and between the two sliders 9.

[0034] Specifically, the clamping assembly 10 includes a clamping plate 11, which is located on one side of the connecting plate 8 close to the display plate 5. In order to limit the movement of the clamping plate 11, the upper and lower ends of the clamping plate 11 close to the connecting plate 8 are fixedly connected with a round rod 12. The end of the round rod 12 away from the clamping plate 11 extends through the connecting plate 8 to the outer side of the connecting plate 8 away from the clamping plate 11 and is fixedly connected with a limiting block 13. The limiting block 13 can prevent the round rod 12 from falling off the connecting plate 8.

[0035] Specifically, a bearing 14 is fixedly connected to the middle part of the clamping plate 11 near the connecting plate 8, and a screw 15 is rotatably connected to one end of the bearing 14 near the connecting plate 8. The end of the screw 15 away from the bearing 14 extends through the connecting plate 8 to the outer side of the connecting plate 8 away from the clamping plate 11 and is fixedly connected to a turning handle 16. The screw 15 is threadedly connected to the connecting plate 8.

[0036] Through the above structural design, it can be known that when it is necessary to clamp the drawings on the display board 5, the distance between the two clamping mechanisms 7 can be adjusted according to the size of the drawings, and the connecting plate 8 can be pushed, so that the connecting plate 8 drives the slider 9 to slide inside the first slide groove 6. When the two connecting plates 8 are moved to a suitable position, the drawings can be placed on the display board 5 and clamped and fixed by the clamping assembly 10. When it is necessary to clamp it, the handle 16 can be rotated, so that the handle 16 drives the screw 15 to rotate. Through the connection between the screw 15 and the connecting plate 8, when the screw 15 rotates, the screw 15 pushes the clamping plate 11 to approach the display board 5 through the bearing 14. Through the approach of the clamping plate 11 to the display board 5, the clamping plate 11 can clamp and fix the drawings on the display board 5.
