Title: HANDHELD MANUAL ENERGY ACCUMULATION YO-YO
Abstract:
A handheld manual energy accumulation yo-yo, comprising two rotary members (1) and a connection shaft (2); the rotary members (1) each comprise a disc (11) and a shell (12); one disc (11) is internally provided with a clutch mechanism, and the other disc (11) is internally provided with an energy accumulation mechanism; the two ends of the connection shaft (2) are connected to the clutch mechanism and to the energy accumulation mechanism, respectively; the rotary member (1) at the clutch mechanism end is manually rotated such that the energy accumulation mechanism accumulates energy, and then the engaged clutch mechanism is manually released such that the energy accumulation mechanism releases energy, thereby driving the two rotary members (1) to spin simultaneously. In this way, the yo-yo can be made to spin without being cast downward by means of the string; even if the string is too short to properly cast the yo-yo downward, the yo-yo can still spin at a high rate of speed and is not subject to acceleration area requirements. The present invention allows for all manner of yo-yo tricks to be performed while satisfying the requirements of players of all ages and heights.
