The side surface of the rotating disk has several sets of anti-slip grooves, and the top surface of the rotating disk has a cross groove. An installation ring is installed at the bottom edge of the rotating disk, and several sets of rolling balls are movably hinged to the bottom end of the installation ring. A screw is installed at the bottom center of the rotating disk.

[0008] Preferably, the two sets of connecting rings are connected and installed by a connecting plate.

[0009] Preferably, the plurality of limiting balls are arranged symmetrically with the center point of the connecting ring as the center point, and the outer surfaces of the plurality of limiting balls are all fitted to the side surfaces of the mounting column.

[0010] Preferably, the anti-slip grooves are arranged in a centrally symmetrical manner with the center point of the rotating disk as the center point.

[0011] Preferably, the thickness of the mounting ring is adapted to the distance between the two inner walls of the annular groove, and the bottom end of the mounting ring extends into the interior of the annular groove and is slidably connected to it.

[0012] Preferably, the several groups of rolling balls are arranged symmetrically around the center point of the mounting ring, and the outer surfaces of the several groups of rolling balls are fitted against the inner wall of the bottom end of the annular groove.

[0013] Preferably, the bottom end of the screw extends into the interior of the mounting hole and is movably screwed thereto.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By incorporating components such as mounting posts, mounting holes, connecting rings, annular grooves, limit balls, connecting plates, rotating discs, anti-slip grooves, cross grooves, mounting rings, rolling balls, and screws, the problem of cumbersome operation and long installation time, which reduces installation efficiency, when installing existing connecting rings and chains can be effectively solved.

[0016] The user can place the two sets of connecting rings onto the outer surface of the corresponding mounting posts at the top of the chain body, so that the outer surfaces of the corresponding sets of limiting balls can fit against the outer surfaces of the corresponding mounting posts. Then, the screw can be aligned with the inside of the mounting hole. At this point, the user can rotate the rotating disc through the anti-slip groove, causing the screw to rotate accordingly, thus screwing the screw into the inside of the mounting hole. When the rotating disc can no longer be turned manually, the user can use a Torx screwdriver aligned with the cross groove and continue rotating the disc until it can no longer be turned. This completes the installation between the rotating disk and the connecting ring, and thus the installation between the connecting ring and the mounting post. Simultaneously, the mounting ring extends into the annular groove, allowing the outer surfaces of several sets of rolling balls to fit against the inner wall of the bottom of the annular groove. Using the same method, another set of rotating disks is used to install another set of connecting rings and another set of mounting posts, thus completing the installation between the top ends of the two chain bodies. The bottom ends of the two chain bodies can then be installed in the same way. See the diagram for details. This process continues until the entire chain is connected and installed.

[0017] Using this connection and installation method, when the entire chain body is subsequently wound around the gear, the chain body can rotate accordingly. While rotating, several sets of limiting balls can roll against the outer surface of the mounting post, and several sets of rolling balls can roll against the inner wall of the bottom of the annular groove. This allows the chain body to change angle freely, thus enabling it to be smoothly wound around the gear. Attached Figure Description
