ABSTRACT:
The present invention discloses a combination changing mechanism for a combination lock comprising a plurality of dial wheels rotatably mounted to the housing of the combination lock, each including a first shaft and a plurality of first teeth extending axially and arranging equidistantly on the outer surface of the first shaft; a plurality of combination changing wheels, each inlcuding a bore for receiving one of the first shaft, an elongated slot communicating with the bore and extending through one side of the combination changing wheel so that the combination changing wheel can be deformed and expanded slightly by a pushing force from one of the dial wheel acting to the peripheral wall of the bore, and a plurality of second teeth on the peripheral wall of the bore to engage with one of the first teeth of the dial wheels; and a movable element having a plurality of stop projections, and capable of being moved to make the stop projections insert respectively into the elongated slots for perventing the combination changing wheels from rotation, whereby the dial wheels can be rotated relative to the combination wheels respectively to change the engaging relationship between the dial and combination changing wheels, so that the combination changing operation is achieved.
