Before the balance weight of the kettle bell is debugged, the kettle bell is integrally arranged on the floor, so that the falling balance weight piece 4 is prevented from damaging people or objects. When the weight of the kettle bell is adjusted, the mandril 21 is firstly pressed to enable the connecting shaft 3 to move downwards, namely, the top surface of the clamping table 61 is separated from the bottom surface of the limiting table 62, then the stopper is rotated (screwed) to replace the stopper, so that the clamping table 61 and the limiting table 62 are staggered in the axial direction, and then the locking of the clamping table 61 on the limiting table 62 is released. At this time, the weight member 4 is in a relatively free state and can be separated from the connecting shaft 3 under the action of self gravity, so that the weight of the kettle bell is reduced.

Similarly, when increasing the weight of the kettle bell, the weight 4 can be inserted into the connecting shaft 3, and then the weight 4 is rotated to find the position-limiting table 62 to align the position-limiting table 61. After finding accurate screens platform 61 position, lift the weight 4 upwards, first spring 22 compression makes the top surface butt of screens platform 61 in the bottom surface of spacing platform 62, realizes the fixed to weight 4 position from this, realizes then the weight gain of kettle bell.

Referring to fig. 2 and 3, based on the structure of the operating assembly, a two-lock error-proof safety adjustment function can be formed, and the weight of the kettle bell can be adjusted by locking or unlocking the selected weight member by utilizing the deflection angle of the connecting shaft. By adopting the scheme, the weight of the kettle bell can be adjusted, the operation is simple and quick for a user, the time consumed by the user in the process of adjusting the weight of the kettle bell can be effectively reduced, and the experience of the user is improved.
