    • The disclosure provides a roly-poly toy with adjustable center of gravity, comprising a first base part, a first winding mandrel mounted on the first base part, a second base part, a second winding mandrel mounted on the second base part, a reel belt, and a drive assembly. The first base part and the second base part are arranged at an interval. The reel belt is annular and has a first end wound around the first winding mandrel and a second end wound around the second winding mandrel. The drive assembly can switch between a first driving state and a second driving state. When the drive assembly is in the first driving state, the first winding mandrel rotates to roll up the reel belt, and the second winding mandrel rotates to release the reel belt. When it is in the second driving state, the second winding mandrel rotates to roll up the reel belt, and the first winding mandrel rotates to release the reel belt. The disclosure changes the center of gravity of the roly-poly toy by changing the weights of the reel belt applied to the first winding mandrel and to the second winding mandrel, thereby enabling the roly-poly toy to amuse users of different ages. It relates to the technical field of entertainment devices.
