1. A kettlebell, comprising:
a plurality of counterweights placed in a vertically stacked manner, wherein two opposite side edges of each of the counterweights are provided with hitching lips, which protrude outwards and are centrosymmetric relative to the center point of an upper surface of each of the counterweights, and inserting openings, which penetrate through upper and lower surfaces of each of the counterweights and are centrosymmetric relative to the center point of the upper surface of each of the counterweights, each of the counterweights is provided with sliding grooves below the hitching lips, and each of the inserting openings is in communication with the sliding groove formed at the bottom of the corresponding hitching lip of the corresponding counterweight;
widths of the inserting openings on two sides of the counterweights from top to bottom are sequentially increased towards the hitching lips, and correspondingly, lengths of the hitching lips from top to bottom are sequentially reduced; and
a lifting base, wherein the lifting base is internally provided with an adjusting assembly, the adjusting assembly comprises a plurality of first load-bearing blocks and a plurality of second load-bearing blocks corresponding to the first load-bearing blocks in number and position, the first load-bearing blocks and the second load-bearing blocks are respectively arranged on two opposite sides of the counterweights, when the first load-bearing block on each layer and the second load-bearing block on each layer sequentially and respectively penetrate through the corresponding inserting openings of the corresponding counterweight on the layer from top to bottom and horizontally move into the sliding grooves below the corresponding hitching lips, the first load-bearing block and the second load-bearing block on each layer can be correspondingly hitched to the corresponding counterweight, and when the first load-bearing blocks and the second load-bearing blocks horizontally move to the corresponding inserting openings, hitching to the counterweights on the corresponding layers is released.
