Abstract
The present invention discloses a hand-held yo-yo ball capable of manually storing energy, comprising two rotating bodies and a connecting shaft, where each rotating body comprises a disk body and a shell; one disk body is internally provided with a clutch mechanism, the other disk body is internally provided with an energy storage mechanism; two ends of the connecting shaft are respectively connected with the clutch mechanism and the energy storage mechanism; the rotating body at the end where the clutch mechanism is located is manually rotated, energy is stored in the energy storage mechanism, then the meshing state of the clutch mechanism is manually removed, so that the energy storage mechanism releases the energy to drive the two rotating bodies to rotate synchronously. In this way, the yo-yo ball can be rotated without throwing a ball body of the yo-yo ball by a rope.
