[0040] Embodiment 2

[0041] like Figure 1-Figure 11As shown, based on the first embodiment, a third sliding groove 39 is provided on the side of the triangular block 10, a limiting block 40 is movably connected to the third sliding groove 39, a limiting block 40 is threadedly connected to a fixing bolt 41, and the limiting block 40 is located on the motion track of the second fixing block 13, a square groove 18 is symmetrically provided on the inner side of the base 1, a storage plate 19 is slidably arranged on the inner side of the square groove 18, a second sliding groove 21 is symmetrically provided on the upper part of the base 1, a second sliding block 22 is slidably arranged inside the second sliding groove 21, and the second sliding block 22 is close to One side of the drawing board 2 is fixedly connected to the storage board 19, a second movable plate 23 is installed on the side of the second sliding block 22 away from the drawing board 2, a first fixed groove 26 and a second fixed groove 33 are symmetrically opened on the upper part of the base 1, the second movable plate 23 is movably connected to the movable rod 25, a third spring 24 is installed on the side of the second movable plate 23 away from the base 1, a side of the third spring 24 away from the second movable plate 23 is fixedly connected to the movable rod 25, and the first fixed groove 26 and the second fixed groove 33 are both movably connected to the movable rod 25;

[0042] A first rack 27 and a second rack 28 are slidingly arranged on the inner side of the base 1, and the first rack 27 and the second rack 28 are fixedly connected to the storage plate 19. A plurality of gears 29 are rotatably connected to the inner side of the base 1, and the plurality of gears 29 are meshed with the first rack 27 and the second rack 28. A second rotating rod 30 is installed on the side of the gear 29 close to the drawing board 2, and a first fan blade 31 is installed on the end of the second rotating rod 30 away from the gear 29. A storage groove 32 is provided on the side of the two storage plates 19 close to the drawing board 2, and the first rack 27 and the second rack 28 are movably connected to the storage groove 32.

[0043] In this embodiment, when the angle of the drawing board 2 needs to be adjusted for drawing, the first movable plate 17 is first pulled to move the first movable plate 17 along the first sliding groove 14 through the first sliding block 16. At this time, the second spring 15 is stretched, and the first movable plate 17 can drive the arc plate 11 to move when it moves, until the first fixed block 12 and the second fixed block 13 are separated. At this time, the drawing board 2 can be rotated to rotate the drawing board 2 through the first rotating rod 7, and at the same time drive the second fixed block 13 to rotate. When the drawing board 2 is adjusted to a suitable angle, the first movable plate 17 can be released, and the stretched second spring 15 drives the first movable plate 17 to reset through the first sliding block 16. At the same time, the first fixing block 12 is driven to reset through the arc plate 11, and the second fixing block 13 is limited by the first fixing block 12 again, so that the drawing board 2 can be adjusted to the desired angle, and when adjusting, the limiting block 40 can be slid along the third sliding groove 39 until the limiting block 40 abuts 13, and then the limiting block 40 is fixed by the force generated by rotating the fixing bolt 41. At this time, the angle adjusted by the second fixing block 13 can be memorized. When using it next time, the drawing board 2 is directly rotated to make the second fixing block 13 abut the limiting block 40, which indicates that it is adjusted to the last angle. The angle adjusted last time can be memorized, which is convenient for accurate adjustment to the last used angle, thereby improving work efficiency.

[0044] When the drawing board 2 is used, the servo motor 37 can be started, and the second fan blade 38 can be driven to rotate by the servo motor 37. The wind force generated by the rotation of the second fan blade 38 can be used to dissipate heat for the drawing board 2, so as to avoid the drawing board 2 generating high temperature due to long-term operation, resulting in a slow heat dissipation process and an increase in the internal temperature of the drawing board 2, which can cause the drawing board 2 to freeze due to high temperature and reduce the drawing efficiency. When the drawing board 2 is rotated by the first rotating rod 7, the third rotating rod 34 can be driven to rotate by the transmission belt 36, and the third movable plate 35 can be driven to rotate at the same time, so that the second fan blade 38 can rotate with the drawing board 2, so as to facilitate the wind direction to always face the drawing board 2 for heat dissipation.

[0045] In addition, the cleaning brush 20 can be used to clean the drawing board 2 during the movement of the storage plate 19, and when the two storage plates 19 move, the first rack 27 and the second rack 28 can be driven to move. Since the first rack 27 and the second rack 28 are both meshed with the gear 29, when the two storage plates 19 move, the gear 29 can be driven to rotate by the first rack 27 and the second rack 28, and the first fan blade 31 can be driven to rotate by the second rotating rod 30. When the two storage plates 19 are in contact, the first rack 27 and the second rack 28 can be driven to be inserted into the storage groove 32 respectively, and the wind force generated by the rotation of the first fan blade 31 can process the impurities attached to the surface of the drawing board 2 and the impurities cleaned out by the second sliding groove 21, thereby improving the flatness of the surface of the drawing board 2 and avoiding the stirring of impurities adsorbed on the drawing board 2, which affects the touch of the brush on the drawing board 2 and the generation of lines when drawing.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
