Abstract
A roly-poly toy with adjustable center of gravity, comprising a first and second base part arranged at an interval, a first winding mandrel mounted on the first base part, a second winding mandrel mounted on the second base part, a reel belt, and a drive assembly. 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.
