The sleeve 112 of the assembly rod 11 of the kettle bell 1 is in threaded connection with the first connecting rod 113, and the total length of the sleeve 112 and the first connecting rod 113 can be adjusted by rotating the sleeve 112, so that the adjustment of the length of the assembly rod is realized, and the assembly rod can be adjusted to be in a length matched with the total thickness of the balancing weight. That is, the longer the first connecting rod 113 rotates into the sleeve 112, the shorter the overall length of the assembling rod 11, the fewer the number of weight blocks 15 that can be assembled, and the smaller the overall weight of the kettle bell 1. The length of the first connecting rod 113 which rotates into the sleeve 112 is short, the whole length of the assembling rod 11 is long, the number of the weight blocks 15 which can be assembled is increased, and the whole weight of the kettle bell 1 is large. Therefore, the length of the assembly rod 11 can be adjusted through threaded connection, so that the function of assembling different numbers of balancing weights 15 is realized, for example, 3, 4, 6, 8 or even more balancing weights can be installed, and the aim of adjusting the whole weight of the kettle bell is fulfilled. At the same time, the mounting bar 11 does not protrude beyond the longer portion due to the small difference in thickness between the mounting bar and all of the weights 15 mounted. This avoids the longer portion of the mounting bar extending from one side of the weight 15 and injuring the user, as opposed to a conventional fixed length mounting bar. Ensures the stability and safety of the kettle bell during training, realizes the weight adjustment of the kettle bell, and facilitates the storage of the detached balancing weight when the kettle bell is required to be light.
