External structure of crystal ball driven by an eccentric shaft
 The present invention is directed to an external structure of a crystal ball that has an eccentric shaft and a swinging stick, which is driven by the eccentric shaft. The eccentric shaft is driven by the revolving shaft of the rotary table on the music box. The swinging stick has a longitudinal concave pedestal that is installed on the end of the eccentric shaft, and is driven to swing around the positioning axis by the rotation of the eccentric shaft so that the phenomena of swinging and other motions can be performed by the swinging stick.
