The working principle is as follows:

in the process of using the device, the lower open box body 1 and the upper open box body 2 in the box body are firstly buckled to form an accommodating space, so that a folding tool storage space and a folding support can be accommodated, and the drawing board frame of the device is convenient to carry through folding. When carrying, utilize fixed buckle 32 to fix the lower uncovered box body 1 and the last uncovered box body 2 of lock, prevent both to scatter. The device can be lifted by using the lifting handle 33 to carry, or carried on the back by using the double-shoulder straps 34, which is convenient and labor-saving. Wherein the lower open box body 1 and the upper open box body 2 are hinged through a hinge structure in the hinged rotating body. Specifically, the rotating disc 3 in the hinged rotating body is embedded through the upper opening 4 on the upper open box body 2, so that the rotating disc 3 is fixed on the upper open box body 2 and can drive the rotating disc 3 to rotate along with the overturning of the upper open box body 2. Wherein the other end of the rotating disc 3 is also embedded into the upper opening 4 on the lower open box body 1, and a certain gap is arranged between the rotating disc 3 and the upper opening 4, so that the rotating disc 3 can rotate relative to the upper opening 4, the upper opening 4 plays a role in accommodating the rotating disc 3, and the lower open box body 1 and the upper open box body 2 can be buckled structurally. Wherein the hinge structure between rolling disc 3 and the box body 1 that opens downwards comprises axis of rotation 7 on the rolling disc 3 and the fixed cylinder seat 6 on the box body 1 that opens downwards, and when driving rolling disc 3 along with the upset of last open box body 2 and rotating, rolling disc 3 will drive axis of rotation 7 and rotate at fixed cylinder seat 6 also. When the lower open box body 1 and the upper open box body 2 are mutually buckled, the upper open box body 2 is flatly placed and can be used as a desk board for writing and the like. No matter the lower open box body 1 and the upper open box body 2 are flatly placed or the upper open box body 2 is turned, the foldable support can be unfolded to support the whole device. Specifically, the bottom groove 25 on the accessible open box body 1 holds down when the foldable support is folded, and occupation space is not. And the magnetic attraction between the third magnet 27 and the fourth magnet 28 on the first support 26 enables the two support legs at the tail end of the first support 26 to be adsorbed at the upper bottom part in the bottom groove 25, and similarly, the magnetic attraction between the fifth magnet 30 and the sixth magnet 31 on the second support 29 enables the two support legs at the tail end of the second support 29 to be adsorbed at the upper bottom part in the bottom groove 25, so that the first support 26 and the second support 29 are more stably folded and stored. After the first support 26 and the second support 29 are turned over, the upper end parts of the first support 26 and the second support 29 are limited at the side of the bottom groove 25, so that the first support 26 and the second support 29 cannot be turned over any more after being turned over to a certain angle, the limiting angle can be adjusted through the distance between the upper ends of the first support 26 and the second support 29 and the side of the bottom groove 25, the farther the distance between the upper ends of the first support 26 and the second support 29 and the side of the bottom groove 25 is, the larger the turning angle of the first support 26 and the second support 29 is, and the whole device can be stably supported within the range that the first support 26 and the second support 29 are turned over more than 90 degrees but not more than 105 degrees. When using the drawing board support afterwards, open box body 2 is gone up in the upset after suitable angle, open box body 2 is gone up to adjusting inclination through the electrodeless fixed establishment in inclination fixes, make it unable continuation upset, use as the drawing board through 2 outside upper surfaces of last open box body this moment and place the drawing paper, restrict drawing paper landing from last open box body 2 through bar stopper 35, or make the drawing paper compress tightly on last open box body 2 and fix through the magnetic force between the pre-buried metal sheet 36 in magnet briquetting and the last open box body 2, prevent the drawing paper landing. When the upper open box body 2 with the well adjusted inclination angle is fixed through the stepless fixing mechanism for the inclination angle, the screwing head 10 is screwed to drive the supporting rotating shaft 9 to rotate, and then the gear 12 is driven to rotate, and because the gear 12 is meshed with the rack 11, the supporting rotating shaft 9 is driven to move along the extending direction of the rack 11, and then the bearing 13 and the extrusion fixing plate 14 are driven to move. Because the bottom of the extrusion fixing plate 14 is attached to the inner bottom surface of the lower open box body 1, the extrusion fixing plate 14 does not rotate along with the supporting rotating shaft 9 and can move along with the supporting rotating shaft 9 under the action of the bearing 13 when the supporting rotating shaft 9 rotates until the extrusion fixing plate 14 extends into the lower part of the rotating disc 3 and the extrusion fixing plate 14 extrudes the circumferential surface of the rotating disc 3. One surface of the joint of the extrusion fixing plate 14 and the rotating disc 3 can be designed into a shape fitting with the circumferential surface of the rotating disc 3, so that the extrusion fixing plate can be completely fitted on the circumferential surface of the rotating disc 3 to fix the rotating disc 3 by extrusion, the rotating disc 3 can not rotate, and the box body 2 with the upper opening can not be turned over continuously. Meanwhile, the anti-skid layer 15 is laid on one side surface of the extrusion fixing plate 14 facing the circumferential surface of the rotating disc 3 and is in contact with the circumferential surface of the rotating disc 3, so that the frictional resistance to the circumferential surface of the rotating disc 3 is improved, and the braking effect to the rotating disc 3 is improved. Unless the pressing and fixing plate 14 is actively withdrawn backward, the upper open box 2 is stopped by the pressing and fixing plate 14 regardless of the direction in which it is turned. Because no matter which direction the rotating disc 3 is turned over, the force towards the bottom in the downward opening box body 1 can be given to the extrusion fixing plate 14, and thus the friction force between the extrusion fixing plate 14 and the bottom in the downward opening box body 1 can be increased. Wherein the supporting rotating shaft 9 moves along the limiting sliding opening 8 when moving, so that the supporting rotating shaft 9 can not move up and down, the gear 12 is firmly attached to the rack 11 and meshed with the rack, and the gear transmission is more stable. Then the screwing head 10 is rotated reversely, so that the extrusion fixing plate 14 is separated from the rotating disc 3, and the upper open box body 2 can be turned over again for adjustment. In the process of using the drawing board frame, the tool storage space is utilized to store drawing tools such as drawing paper and painting brushes at any time, the package is not required to be prepared, the drawing board frame and the drawing tools are stored in one place, and the drawing board frame is convenient to carry. Specifically, the turnover buckle plate 21 on the upper open box body 2 can be turned over relative to the upper open box body 2, and the turnover buckle plate 21 can be fixed on the upper open box body 2 by utilizing the mutual attraction of magnetism between the first magnet 22 and the second magnet 23. When the turnover buckle plate 21 is turned over, the concertina type bag 24 between the turnover buckle plate 21 and the box body 2 with the upper opening is also unfolded, and drawing paper or paper documents can be placed in the concertina type bag 24. Meanwhile, the turnover cover plate 20 in the lower open box body 1 can be lifted, so that the first drawer box 17 and the second drawer box 19 are exposed, and painting tools such as paintbrushes and the like are placed in the exposed first drawer box 17 and the exposed second drawer box 19. Wherein, the first drawer box 17 and the second drawer box 19 can be internally provided with a separation plate and the like, which is suitable for the shape of a pigment barrel or a painting brush, and is convenient and practical. Wherein the flip cover 20 covers the first and second drawer boxes 17 and 19 to protect the drawing tools in the first and second drawer boxes 17 and 19 from scattering. Simultaneously under open box body and last 2 locks of open box body overturn buckle 21 can compress tightly and fix it on upset apron 20, when preventing to carry, because rock and make upset apron 20 break away from first drawer box 17 and second drawer box 19 and make the drawing instrument scatter. Still can use first drawer box 17 from first opening 16 take out down outside the uncovered box body 1, or use second drawer box 19 from second opening 18 take out down outside the uncovered box body 1, wherein when first drawer box 17 pushes back in the uncovered box body 1 down, be interference fit between first drawer box 17 and the first opening 16, when second drawer box 19 pushes back in the uncovered box body 1 down, be interference fit between second drawer box 19 and the second opening 18, first drawer box 17 and second drawer box 19 drop when preventing to carry. Or the first drawer box 17 and the second drawer box 19 can be provided with magnets, and the magnets are fixed through the magnetism between the magnets corresponding to the lower opening box body 1, or the first drawer box 17 and the second drawer box 19 can be fixed with the lower opening box body 1 through additionally arranging buckles.
