[0002] Fitness equipment is a kind of sports equipment used by people who have fitness needs to assist in exercise and strengthen their bodies. There are different equipment for different effects, most of which are placed in gyms. Most of the fitness equipment that is not driven by a driving device is generally composed of multiple parts spliced ​​together by fastening bolts or other fixed structures.

[0003] However, due to the wide variety of fitness equipment, the parts of the fitness equipment are diverse and complex, making it difficult to unify the models of the fastening structures used in various fitness equipment. The length of the fastening bolts used in some fitness equipment may be shorter, and the length of the fastening bolts used in some fitness equipment may be longer, so that if the fastening bolts of one fitness equipment are lost or damaged, it is difficult to adapt and install the fastening bolts of other models.

[0007] The adjustment mechanism includes a thin screw, which is rotatably connected in the middle of the through slot, and one end of the thin screw passes through the hexagonal block. A slider is threadedly connected to the outer periphery of the thin screw, and the slider is slidably connected to the inner wall of the through slot. A gasket is provided at one end of the slider, and a turning handle is fixed to one end of the thin screw. A square groove is provided near the turning handle of the thin screw, and a sliding frame is slidably connected to the position of the square groove of the thin screw. A fixed disk is fixed to the end face of the hexagonal block facing the turning handle, and a plurality of slots are provided on the inner circle of the fixed disk.

[0008] Preferably, the length of the threaded section of the thin screw is the same as the length of the through groove.

[0009] Preferably, there is a one millimeter gap between the inner ring of the gasket and the outer ring of the thin screw, and a rubber layer is provided at one end of the gasket.
