The fastening bolt 44 can simultaneously satisfy the functions of locking the hexagonal locking guide rail 41 and the indexing pin.
[0046] In an embodiment, the rotating assembly 51 comprises a fixed disc 511, a mounting plate 512 and a fixed seat 513. The fixed disc 511 is fastened to the guide rail 41, the mounting plate 512 is fastened to the cabinet 1 of the fitness system, and the fixed seat 513 is fastened to the mounting plate 512 by screws. The fixed disc 511 and the fixed seat 513 are located on both sides of the mounting plate 512 and are connected by bearings 514.
[0047] The fixed disc 511 is provided with a damping assembly 53 on the circumferential side. The damping assembly 53 comprises a fixed plate 531, a second spring 532, a damping bracket 533 and an external threaded bearing 534. The fixed plate 531 is fastened to the mounting plate 512. One end of the second spring 532 is mounted to the fixed plate 531. The damping bracket 533 is rotatably mounted to the fixed plate 531 by a shoulder screw and a washer. One end of the damping bracket 533 abuts the other end of the second spring 532. The external threaded bearing 534 is connected to the other end of the damping bracket 533 by threading. The fixed disc 511 is provided with a damping groove 535 on the circumferential side.
