[0042] Specifically, the two devices are aligned with each other to ensure that the left reserved hole 201 of one device is aligned with the right reserved hole 201 of the other device. At this time, by moving the pull rod 202 along the L-shaped groove 204, the threaded rod 203 can be driven to extend from the right reserved hole 201 and smoothly extend into the left reserved hole 201 of the other device. At the same time, the knob 208 of the other device is turned to drive the second bevel gear 207 to rotate. Rotating the second bevel gear 207 will drive the first bevel gear 206 and the threaded cylinder 205 thereon to rotate together through meshing transmission. The rotating threaded cylinder 205 is fixed together with the inserted threaded rod 203 through threaded connection to fix two or more devices to each other. Since this fixing method may not be stable enough at this time, in order to improve the stability of the connection between multiple devices, the block 210 on the right side of the device can be slid to the right so that the block 210 is engaged with the left groove 209 of another device. The engagement design can significantly enhance the stability of the connection to avoid shaking after connection, and ensure the firmness of the connection between multiple devices. The device is also equipped with a hinge 15 to open and close the movable door 16. When the device is not in use, the movable door 16 can effectively prevent dust and impurities from entering the interior of the box 1, thereby keeping the box 1 clean and intact.

[0043] Reference Figure 1 and Figure 3 The bottom of the inner wall of the bracket 4 is fixedly connected with a storage box 13, and the inner side of the storage box 13 is slidably connected with a drawer 14; the bottom of the inner wall of the box body 1 is fixedly connected with a magnetic plate 21, and the top of the outer wall of the magnetic plate 21 is provided with a plurality of magnetic nails 22; a handle 20 is provided in the middle of the rear side of the box body 1, and the left and right sides of the front end of the handle 20 are rotatably connected with a U-shaped block 19, and the front side of the U-shaped block 19 is fixedly connected to the box body 1;

[0044] Specifically, a storage box 13 is connected to the bottom of the inner wall of the bracket 4, and the inner side of the storage box 13 can be slidably connected to the drawer 14, making it more convenient to classify and store items to improve practicality and meet the user's needs for space utilization and organization. A magnetic plate 21 is fixed to the bottom of the inner wall of the box body 1, and a plurality of magnetic nails 22 are arranged on the top of the outer wall of the magnetic plate 21, which can be convenient for storing the magnetic nails 22 when they are not in use. Moreover, the small display board 7 and the large display board 12 are both iron plates, so that the magnetic nails 22 can be convenient for adsorbing and fixing drawings on the outer sides of the large display board 12 and the small display board 7, which can save and make full use of space. A handle 20 is arranged in the middle of the rear side of the box body 1, which makes it more convenient to carry. The left and right sides of the front end of the handle 20 are rotatably connected to the U-shaped block 19. Such a design increases the stability of holding, making it difficult for the box body 1 to slip during movement. The front side of the U-shaped block 19 is fixedly connected to the box body 1, which further enhances the structural strength of the box body 1.

[0045] Working principle: Before using the device, firstly, the rotation angle of the bracket 4 can be adjusted by rotating the rotating rod 3, and the frame 6 can be opened and closed through the hinge seat 5 on the bracket 4. When the frame 6 is opened and closed along the bracket 4, the rotating wheel 8 on it will rotate along the rotating wheel 8 on the bracket 4 through the belt 9. When the rotating wheel 8 on the frame 6 rotates, it will simultaneously drive the small display board 7 fixed at the bottom to rotate along the inner side of the frame 6, so that the small display board 7 can be turned over while the frame 6 is opened and closed, so that the drawings displayed on the small display board 7 will not be covered with the opening and closing of the frame 6, and the opening and closing frame 6 will expose the large display board 12 on the rear side to increase the total area of ​​the display board, thereby improving the practicality of the device, and aligning the two devices with each other, such as the reserved hole 20 on the left side of one device. With respect to the right side reserved hole 201 of another device, by moving the pull rod 202 along the L-shaped groove 204, the threaded rod 203 can be driven to extend from the right side reserved hole 201 and extend into the left side reserved hole 201 of another device. Meanwhile, by rotating the knob 208 of another device, the second bevel gear 207 can be driven to rotate. Rotating the second bevel gear 207 can drive the first bevel gear 206 and the threaded cylinder 205 thereon to rotate. The rotating threaded cylinder 205 can be fixed to the inserted threaded rod 203 through a threaded connection. Since the fixation is not stable at this time, the block 210 on the right side of the device can be slid to the right to engage with the left side groove 209 of another device to improve the stability of the connection between the multiple devices, thereby improving the functionality of the device.
