A storage component is provided on the top of the support plate 2, and a handle 3 is fixedly connected to the outer side of the support plate 2 for easy carrying of the folded device. A groove 20 is formed on the bottom surface of the support plate 2, providing storage space for a backrest 16. The backrest 16 is disposed inside the groove 20, and two rotating blocks 15 are rotatably connected inside the groove 20. A rotating column 14 is rotatably connected inside the groove 20, with both ends of the rotating column 14 rotatably connected to the support plate 2 via bearings embedded inside the support plate 2. The two rotating blocks 15 are symmetrically fixedly sleeved on the outer side of the rotating column 14, and one end of the rotating column 14 extends to the outer side of the support plate 2. The top of the support plate 2 has two rectangular grooves 17 that are connected to the groove 20, and two rotating blocks 15 are fixedly connected to the back plate 16. The outer side of the support plate 2 is provided with a limit component. The bottom end face of the support plate 2 is symmetrically fixedly connected with a fixing block 4. The front and rear adjacent fixing blocks 4 are rotatably connected with a support leg 10 and a support rod 11. The front and rear adjacent fixing blocks 4 are rotatably connected with a rotating rod 9. The front and rear adjacent fixing blocks 4 are each embedded with a bearing 2 on one side. Both ends of the rotating rod 9 are rotatably connected to the fixing block 4 through the bearing 2. The support leg 10 and the support rod 11 are fixedly sleeved on the outer side of the rotating rod 9. One end of the rotating rod 9 extends to the outer side of the fixing block 4. The outer side of the two fixing blocks 4 is provided with a fixing component. The support rod 11 is provided with an adjustment component.

[0028] Please see Figure 4 and Figure 5The limiting component includes slots 21 and connecting blocks 23. Multiple slots 21 are provided on the outer side of the support plate 2. The connecting block 23 is fixedly connected to the outer side of the rotating column 14. A threaded hole is provided on the connecting block 23. A fastening bolt 22 is inserted into the threaded hole and inserted into the slot 21. The fixing of the connecting block 23 is released, which drives the rotating column 14 to rotate, thereby facilitating the adjustment of the angle of the back plate 16. The angle of the back plate 16 can be controlled and adjusted as needed. After the adjustment is completed, the fastening bolt 22 is screwed into the corresponding slot 21 to fix the back plate 16.

[0029] Please see Figure 1 The fixing component includes a limiting groove 5 and a limiting plate 8. Two limiting grooves 5 are opened on the outer side of the fixing block 4. The limiting plate 8 is fixedly connected to the outer side of the rotating rod 9. The limiting plate 8 has a threaded hole 2. The threaded hole 2 is threaded into the threaded part of the limiting bolt 7. The limiting bolt 7 is inserted into the inside of the limiting groove 5. When the device needs to be used, the fixing of the limiting plate 8 is released, and the two rotating rods 9 are rotated outward by 90 degrees. At this time, the limiting bolt 7 corresponds to the other limiting groove 5. Then, the limiting bolt 7 is screwed into the inside of the limiting groove 5, thereby fixing the rotating rod 9 after rotation.

[0030] Please see Figure 2 The adjustment assembly includes a connecting groove and fixing bolts 13. A connecting groove is provided on the support rod 11, and a rectangular plate 19 is slidably inserted into the connecting groove. A support base 12 is fixedly connected to the rectangular plate 19. A threaded hole 3 communicating with the connecting groove is provided on the support rod 11, and a fixing bolt 13 is threadedly inserted into the threaded hole 3. Multiple fixing grooves 18 are provided on the rectangular plate 19, and the fixing bolts 13 are inserted into the fixing grooves 18. Releasing the fixing of the rectangular plate 19 allows it to move within the connecting groove, thus facilitating adjustment of the support rod 11. The total length of the support rod 11 and the rectangular plate 19 is adjusted to allow for adjustment of the total length of the support rod 11 and the rectangular plate 19 supporting the bottom rear side of the support plate 2. In actual use, this allows the user to adjust the length of the rectangular plate 19 protruding from the outside of the support rod 11 according to the height of the steps, and to make the fixing bolt 13 correspond to the fixing groove 18. This makes it convenient for the user to sit on the steps of the exhibition hall. After adjustment, the fixing bolt 13 is tightened so that it is inserted into the corresponding fixing groove 18, thereby fixing the rectangular plate 19.

[0031] Please see Figure 4 and Figure 5The storage component includes a storage box 1 fixedly connected to the top of the support plate 2. The storage box 1 is equivalent to a seat plate and can also be used to store items. The top of the storage box 1 has an insertion hole 6, and a baffle 24 is inserted into the insertion hole 6. The surface of the baffle 24 has a groove. By inserting a hand into the groove, the baffle 24 can be moved upward, thereby making it easy to remove the baffle 24 from the storage box 1 and thus making it easy to put or take items into the storage box 1.

[0032] The implementation principle of this application embodiment is as follows: When the device is not in use, the fixing of the connecting block 23 is released, causing the rotating column 14 to rotate. The rotation of the rotating column 14 causes the back plate 16 to rotate, rotating the back plate 16 into the groove 20, thereby folding and storing the back plate 16. Then, the fastening bolt 22 is tightened and inserted into the corresponding slot 21 to fix the back plate 16, thereby reducing the size of the device. Then, the fixing of the limiting plate 8 is released, causing the two rotating rods 9 to rotate inward by 90 degrees, rotating the support leg 10 and the support rod 11 to the bottom of the back plate 16. Then, the limiting bolt 7 is tightened and inserted into the corresponding limiting groove 5 to fix the rotating rod 9 after rotation, thereby further realizing the folding of the support leg 10 and the support rod 11, further reducing the size of the device.
