[0029] Example 2: Figure 1 , Figure 3 , Figure 5 As shown, a fixing plate 46 is provided on the inner wall of the adjusting rod 21, a side block 47 is provided on the surface of the adjusting rod 21, a sliding rod 49 is provided inside the side block 47, a second pull block 50 is provided on the surface of the sliding rod 49, a second stop block 51 is provided on the back of the sliding rod 49, a spring 52 is provided on the surface of the second stop block 51, and a locking block 53 is fixedly installed on the back of the second stop block 51. The fixing plate 46 is symmetrically distributed on the left and right ends of the back of the adjusting rod 21. The sliding rod 49 slides inside the side block 47 through the sliding groove 48. The spring 52 is fixed to the inner wall of the side block 47 at the end away from the second stop block 51. The spring 52 is slidably connected to the sliding rod 49. The locking block 53 is slidably connected to the cushion 22 through the fixing groove 54.

[0030] In this embodiment, precise control of the position of the backrest 22 is achieved.

The design of the locking block 53 and the fixing groove 54 ensures a reliable connection between the backrest 22 and the adjusting rod 21, preventing displacement during use. This not only simplifies the operation process, but also improves the accuracy and convenience of adjustment, and enhances the adaptability and comfort of the seat.

[0031] The working principle of this embodiment is as follows: In use, first place the storage box 1 in the desired position, then pinch the seat cushion body 9 and pull upwards. This causes the second seat cushion support rod 12 to slide upwards inside the storage box 1 via the fourth rotating rod 13, and rotate on the surface of the second protrusion 10 via the third rotating rod 11. Simultaneously, the first seat cushion support rod 6 rotates on the back of the limiting block 4 via the first rotating rod 5, and rotates on the inner wall of the first protrusion 8 via the second rotating rod 7. At this time, the limiting block 4 slides inside the limiting plate 2 via the limiting groove 3. Then, pinch the first handle 18 to align the fixing rod 16 with the first threaded groove 15 and rotate it, causing the fixing rod 16 to move towards the first seat cushion support rod 6 via the second threaded groove 17 and the first threaded groove 15. The seat cushion body 9 is then fixed in place by rotating the internal mechanism until the fixing rod 16 is attached to the back of the second seat cushion support rod 12. The baffle 14 then secures the seat cushion body 9. Next, the backrest 22 is pinched and pulled upwards, causing the adjusting rod 21 to rotate upwards inside the seat cushion body 9 via the fifth rotating rod 20. This rotation causes the locking pad 23 to rotate upwards as well. Once the locking pad 23 has completely slid out of the seat cushion body 9 through the first locking groove 24, the adjustment is complete. The adjusting rod 21 is then attached to the left side of the first stop block 19. Finally, the second pull block 50 is pinched and pulled backwards, causing the sliding rod 49 to slide backwards through the sliding groove 48 inside the side block 47. The sliding rod 49, along with the locking block 53, slides backwards via the second stop block 51. Once the locking block 53 has fully slid into the side block 47 and out of the cushion 22 through the fixing groove 54, then pinch the cushion 22 and pull it upwards, causing it to slide upwards inside the fixing plate 46. Once the cushion 22 has fully slid to the desired position, release the second pull block 50. Under the elastic force of the spring 52, the locking block 53 will slide towards the cushion 22 through the second stop block 51. Once the locking block 53 has fully slid into the cushion 22 through the fixing groove 54, it will be firmly fixed. Finally, pinch the tabletop body 41 and pull it upwards, causing the tabletop support rod 27 to rotate upwards on the surface of the first fixing block 25 via the first rotating rod 26. Once the tabletop support rod 27 has rotated to the desired position, then pinch the auxiliary support rod 29. Pull to the right to rotate the auxiliary support rod 29 via the second rotating rod 28, and then achieve the supporting effect through the positioning block 30. Next, pinch the sliding plate 34 and pull it upwards, causing it to slide upwards through the sliding groove 33 inside the tabletop support rod 27. Simultaneously, the adjusting block 35 slides through the adjusting groove 32 inside the adjusting convex plate 31. Once the sliding plate 34 has slid to the desired position, pinch the second handle 38 and rotate it, causing the threaded rod 37 to rotate through the third threaded groove 36 into the adjusting block 35 for a fixing effect. Finally, pinch the tabletop body 41 and rotate it, causing it to rotate through the third rotating rod 39 on the surface of the second fixing block 40, thus rotating the tabletop body 41 to the desired angle.Then, pinch the first pull block 45 to align the locking lever 44 with the second locking groove 43 and press it inward, causing the locking lever 44 to slide through the second locking groove 43 into the side plate 42 and the sliding plate 34, thereby firmly fixing the tabletop body 41.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
