The inner cavity of the shell three 41 is slidably connected with a card plate 43, and the rear part of the shell three 41 is rotatably connected with the middle part of the inner cavity of the two fixed blocks 25. The left and right sides of the rear end of the shell three 41 are provided with limit grooves, and the left and right ends of the card plate 43 are slidably connected with limit blocks, and the two limit blocks are matched with the limit holes 42 opened on both sides of the shell three 41.

[0029] Furthermore, in the specific implementation process, by setting the device housing 21 to cooperate with the device pull rod 27, the painter can pull the device pull rod 27 to drive the device box 2 to move as a whole, thereby saying goodbye to the traditional method of using both hands to pick up the painting tools, which is inconvenient to pick up other items. Further, by setting the rear end of the device 44 to cooperate with the device inclined groove 26, the painter can fix the drawing board by folding, so that the painter can adjust and clamp the drawing board of any size purchased by the painter. Further, by setting two device storage components 3 to cooperate with the two sliding grooves 23 opened in the inner cavity of the housing 21, the painter can classify the drawing paper and the drawing tools into the inner cavities of the two device storage components 3, so as to facilitate the painter to store and classify. Further, by setting the device storage component 3 to cooperate with the device rotating groove 22, the painter can fix the storage component 3 by rotating the front end of the outer surface of the device storage component 3, thereby preventing the device storage component 3 from slipping out during the movement, thereby causing unnecessary problems such as the drawing tools falling off.

[0030] It should be noted that the internal parts of the device limiter 24 are composed of a device ball handle, a connecting rod, a spring and an inclined block, and further their connection relationship is as follows: the two connecting rods are slidably connected to the rear of the shell 1 21, and then the ends of the two connecting rods that are away from each other are fixedly connected to the ball handle, and the ends of the two connecting rods that are close to each other are both fixedly connected to the inclined block, and further the ends of the two inclined blocks that are away from each other are fixedly connected to the spring, and the ends of the two springs that are away from each other are both fixedly connected to the shell 1 21;

[0031] Then, when the device housing 3 41 cooperates with the two limiting grooves on the left and right sides of the rear end, the device housing 3 41 is folded so that the two limiting grooves on the left and right sides of the rear end of the housing 3 41 squeeze the inclined block, so that after the rear end of the device housing 3 41 is folded to a suitable position, the inclined block drives the limiting groove to limit the inclined block through the resilience of the spring itself;

[0032] Furthermore, by arranging two limit blocks slidably connected to the bottom of the left and right sides of the card plate 43, when the painter is painting, the card plate 43 can be adjusted up and down by pressing the two limit blocks, so that the device can be suitable for different drawing boards.

[0033] The working principle of the utility model is as follows: first, when the operator uses the device, the operator pulls the device pull rod 27 which is rotatably connected at the rear end of the device shell 21, and then drives the four device shells 21 fixedly connected at the bottom of the shell 21 to move. Further, when the operator needs to draw, the operator can rotate the rotating rod 33 to release the limit between the rear end of the device rotating rod 33 and the rotating groove 22, so that it is convenient for the painter to take the drawing tool. Further, the front end of the device limiting hole 42 is lifted to make the rear end of the limiting hole 42 cooperate with the inclined groove 26. Further, after the device limiting hole 42 is folded to a certain extent, the device inside the device limiter 24 will limit and fix the limiting hole 42. Further, the painter can stretch the device card plate 43, and the two limiting blocks at the bottom of the device card plate 43 make the device card plate 43 clamp the drawing board, and then adjust the appropriate size according to the size of the drawing board.
