The spring 11 is movably mounted on the corresponding clamping rod 9. The pull ring 10 on the right side is located in the U-shaped handle. With the cooperation between the clamping rod 9 and the corresponding clamping groove 8, the round roller 2 can be restricted. The utility model uses a series of structural settings, and the entire device can support a drawing board and a tablet computer at the same time. The two support methods are integrated into one body to improve the scope of application, and the support height can be adjusted according to the needs of use, so that it can meet the use of people of different heights and improve the flexibility of use. In addition, the four adjustable support mechanisms can be stored in the box-shaped support seat 1 after use, which reduces the total volume of the entire device and is convenient for people to carry.

[0027] Working principle: when the whole device needs to be used, pull the pull ring 10 in the direction away from the box-shaped support seat 1, the pull ring 10 stretches the corresponding spring 11, and at the same time, the pull ring 10 drives the corresponding clamping rod 9 to move out of the clamping groove 8, and releases the fixation of the round roller 2. At this time, the two corresponding support seats 5 can be rotated downward, and the support seat 5 drives the support leg 3 to move out of the box-shaped support seat 1 through the corresponding screw 4, and the support leg 3 drives the corresponding first magnet 7 and the second magnet 6 to separate, and the support leg 3 also drives the corresponding round roller 2 to rotate. When the support leg 3 rotates to a vertical state, the round roller 2 drives the corresponding clamping groove 8 below to align with the clamping rod 9, and then relaxes the tension on the pull ring 10. At this time, the elastic force of the spring 11 in the stretched state is brought by the pull ring 10 The movable card rod 9 moves into the corresponding card slot 8, and with the cooperation of the card rod 9 and the card slot 8, the corresponding round roller 2 is restricted, thereby realizing the restriction of the support leg 3. When the four support legs 3 are all turned out and are in a vertical fixed state, the four support legs 3 cooperate with the screw rod 4 and the support seat 5 to support the entire box-shaped support seat 1. The personnel can directly place the tablet computer on the top right side of the box-shaped support seat 1, and the drawing board is tilted and placed between the inner side of the L-shaped restriction block 13 and the top of the support roller 15. The support roller 15 and the iron support plate 12 cooperate to support the drawing board. The entire device can support the drawing board and the tablet computer at the same time. The two support methods are integrated into one, which improves the scope of application and does not need to set up different brackets separately.

[0028] When supporting the drawing board, when adjusting the inclination angle of its support, the iron support plate 12 can be pulled upward obliquely. The iron support plate 12 is separated from the corresponding strong magnet 16, and the iron support plate 12 is removed from the corresponding positioning sleeve 14 and inserted into the corresponding positioning sleeve 14 according to the required support inclination angle. The setting of multiple positioning sleeves 14 can adjust the inclination support angle of the drawing board and improve the flexibility of use;

[0029] During use, when adjusting the support height of the box-shaped support base 1 according to the usage needs, the corresponding support base 5 can be lifted and rotated. The support base 5 drives the corresponding screw rod 4 to rotate in the thread groove. While the screw rod 4 rotates, it also moves out of the corresponding thread groove. As the length of the screw rod 4 moving out increases, the total support height increases, so that the support height of the box-shaped support base 1 can be adjusted. After the adjustment is completed, stop rotating the support base 5. After all four support bases 5 are adjusted, it can continue to be used for support. The adjustable support height of the box-shaped support base 1 can be suitable for people of different heights and improve the flexibility of use;

[0030] After use, after removing the drawing board and the tablet computer, the support base 5 can be rotated in the reverse direction. The support base 5 drives the corresponding screw rod 4 to rotate and retract into the thread groove. When retracting to the initial length, pull the pull ring 10 away from the box-shaped support base 1 again, so that the latch 9 moves out of the corresponding card slot 8. Immediately, rotate the support leg 3 upward. The support leg 3 rotates into the box-shaped support base 1. The support leg 3 drives the corresponding support base 5 to rotate into the box-shaped support base 1 through the corresponding screw rod 4. The support leg 3 drives the corresponding first magnet 7 to adsorb with the second magnet 6, so as to initially fix the support leg 3. While the support leg 3 rotates, it also drives the corresponding roller 2 to rotate. When the roller 2 drives the corresponding card slot 8 to align with the latch 9, release the pulling force on the pull ring 10, so that the latch 9 rebounds into the corresponding card slot 8 again to limit the roller 2, thereby realizing the secondary fixation of the support leg 3. At this time, the four support legs 3 are received in the box-shaped support base 1, reducing the overall volume of the entire device and facilitating carrying. At this time, the user can carry the entire device through the U-shaped handle.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
