Driving device and spinning top accelerator

Abstract

A spinning top accelerator and a driving device are disclosed. The driving device includes a case and an acceleration gear set which is rotatably provided in the case. A gravity block is slidably provided on the case, and the gravity block is drivingly connected to the acceleration gear set. When the gravity block slides back and forth on the case by swinging, the gravity block drives the acceleration gear set to rotate.
