Referring to Figures 1-3 , a drawing auxiliary tool includes a drawing board 1, a supporting component 5 is arranged at the bottom of the drawing board 1, a fixing clip 2 is fixedly installed on the front end face of the top of the drawing board 1, and a clamping rod 4 is also slidably connected to the front end face of the drawing board 1. The clamping rod 4 is driven by a driving component 3. The driving component 3 includes a sliding groove 31 opened inside the drawing board 1, a threaded rod 32 is rotatably arranged inside the sliding groove 31, a sliding plate 33 is threadedly connected to the outer side of the threaded rod 32, fixing blocks 34 are fixedly installed at both ends of the sliding plate 33, a connecting rod 35 is slidably arranged inside the fixing block 34, one end of the connecting rod 35 is fixedly connected to the clamping rod 4, and a spring 36 is arranged between the other end of the connecting rod 35 and the fixing block 34.

[0021] Here, by pulling up the clamping rod 4, passing the drawing paper through the clamping rod 4, then turning the fixing clip 2 to clamp the drawing paper tightly, releasing the clamping rod 4, and rotating the threaded rod 32, the threaded rod 32 can push the sliding plate 33 to move downward. The sliding plate 33 drives the fixing blocks 34 and the connecting rod 35 to move synchronously, so that the clamping rod 4 can slide downward on the surface of the drawing board 1, thereby the drawing paper can be smoothed, and the bottom of the drawing paper can be clamped to prevent the drawing paper from warping during drawing and affecting the drawing effect.

[0022] Referring to Figure 1 and Figure 3 , the end of the threaded rod 32 penetrates through the bottom wall of the drawing board 1 and is fixedly connected to a turntable 37. A plurality of anti-slip grooves 31 are opened in the circumferential direction of the turntable 37.

[0023] Here, by providing the turntable 37 and opening the anti-slip grooves 31 on the turntable 37, it is convenient to drive the threaded rod 32 to rotate.

[0024] Reference Figure 3 A handle 41 is fixedly mounted on the top wall of the clamping rod 4.

[0025] Here, a handle 41 is provided so that the clamping rod 4 can be pulled to create a gap between the clamping rod 4 and the drawing board 1 so that the drawing can pass through.

[0026] Reference Figure 2 The support assembly 5 includes a vertically arranged lifting sleeve 51, the interior of the lifting sleeve 51 is slidably connected with a column 52, the top of the column 52 is fixedly hinged with a hinge rod 54 through a locking bolt 53, the hinge rod 54 is fixedly connected to the drawing board 1, and a fixing ring 55 is installed on the outer side of the lifting sleeve 51, and a plurality of supporting legs 56 are hinged in the circumferential direction of the fixing ring 55.

[0027] Here, by loosening the locking bolt 53 , the hinge rod 54 can be rotated at the top of the column 52 , so that the angle of the drawing board 1 can be adjusted, and then fixed by tightening the locking bolt 53 .
