ABSTRACT:
A flying block assembly for speed regulation of music box comprises a pair of flying blocks (1), a pair of link arms (2) and a central cylinder (4) which fixes the flying block (1) onto a speed regulating shaft (5), wherein an inertia frame (3) conventionally integrated with the speed regulating shaft (5) is changed to be integrated with the flying block assembly, and can move in axial direction of the speed regulating shaft. As the inertia frame (3) and the flying block assembly combine a connection rather than a separate body, the unthreaded poriton of the speed regulating shaft which is occupied usually by the inertia frame will be left for the flying block assembly moving upward or downward, so that it will cause the flying block for speed regulation to obtain much more adjusting range of axial diection.
