[0028] This embodiment will be described in detail with reference to the accompanying drawings when in use.

[0029] In use, the main support component is divided into four parts: a horizontally arranged support shaft 1, a central support 2 rotatably connected to the support shaft 1, and a left connector 3 and a right connector 4 slidably connected to the left and right ends of the central support 2, respectively. The left connector 3 and the right connector 4 are slidably connected to the left and right ends of the central support 2, making each part a detachable independent unit. This not only facilitates installation, but also allows for the replacement of damaged parts when some of them are damaged.

[0030] The middle support member 2 has connecting rings 5 ​​arranged in a ring at both ends of its outer contour. Multiple connecting holes are opened on the connecting rings 5 ​​for connecting spokes. The left connecting member 3 and the right connecting member 4 are laterally sliding and detachably connected to the middle support member 2, so that when the middle support member 2 rotates, the connecting parts of the left connecting member 3 and the right connecting member 4 rotate synchronously. The left connecting member 3 and the right connecting member 4 are respectively provided with a left rotating inner ring 7 and a right rotating inner ring 9 that are rotatably connected.

[0031] The left connector 3 includes an annular left connector sleeve 6. The left end of the left connector sleeve 6 is provided with an annular cavity to accommodate the left rotating inner ring 7. The right end of the left connector sleeve 6 and the inner side of the left connector sleeve 6 are respectively provided with left annular grooves 12. Multiple circumferentially distributed rollers are provided in the left annular grooves 12. A longitudinally sliding rotating buckle 15 is provided on the left side of the left connector sleeve 6. The left rotating inner ring 7 is provided with an annular rotating groove at the position corresponding to the rotating buckle 15. The rotating buckle 15 extends into the annular rotating groove, so that the left rotating inner ring 7 can rotate in the left connector sleeve 6 without moving along the axis of the support shaft 1 and disengaging.

[0032] The right connector 4 includes an annular right connecting sleeve 8. The right end of the right connecting sleeve 8 has an annular cavity to accommodate a right rotating inner ring 9. The right rotating inner ring 9 is installed inside the right connecting sleeve 8 from right to left. The left end face of the right rotating inner ring 9, where it mates with the inner side of the right connecting sleeve 8, has right annular grooves 13. Multiple circumferentially distributed rollers are located within the right annular grooves 13. A longitudinally sliding rotating buckle 15 is provided on the right side of the right connecting sleeve 8. An annular rotating groove is provided on the right rotating inner ring 9 at a position corresponding to the rotating buckle 15. 15 extends into the annular rotating groove, so that the right rotating inner ring 9 can only rotate and cannot be disengaged. The left side of the inner side of the right connecting piece 4 is provided with multiple detachable arc-shaped fixing pieces 14. Each arc-shaped fixing piece 14 is rotatably connected to a pawl 10. A return spring is provided between the side of the pawl 10 and the arc-shaped fixing piece 14. The right end of the support shaft 1 is fixedly connected to a ratchet 11 that extends into the right connecting sleeve 8. The ratchet 11 and the pawl 10 are positioned opposite each other, so that the support shaft 1 and the middle support piece 2 can rotate in one direction.

[0033] The support shaft 1 has threads at both ends, and fastening nuts 16 are threaded to both ends of the support shaft 1. The inner side of the fastening nuts 16 presses against the outer side of the left rotating inner ring 7 and the right rotating inner ring 9, so that the left rotating inner ring 7 and the right rotating inner ring 9 are connected to the support shaft 1 respectively. The rollers provided on the inner side of the left rotating inner ring 7 and the right rotating inner ring 9 respectively play the role of reducing friction during rotation.

[0034] The right connecting sleeve 8 has a connecting thread for connecting peripheral devices. The connecting thread connects peripheral components such as gear disks. When installing peripheral devices, the direction of rotation of the connecting thread is consistent with the direction of force applied to the peripheral device, so that the peripheral device will not be disconnected due to external force in the working direction. When disassembly is required, it can be removed by rotating it in the opposite direction.

[0035] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
