A combination lock includes a female member, a lock rod inserted in the female member; the female member is inserted through single dial, several actuating rings, and co-moving rings; the dial and the actuating rings are arranged side by side, and releaseably engaged with respective co-moving rings; the dial and an actuating ring adjacent thereto have a projecting portion on opposing sides while every two adjacent actuating rings have a projecting portion on opposing sides such that the co-moving rings can be turned to unlocking position where all gaps thereof oppose a trench of the female member to form a passage for the lock rod by operating the dial; orientations of the dial and the actuating rings relative to respective co-moving rings are changed for changing the unlocking combination by operating the dial after the dial and the actuating rings are disengaged from the co-moving rings.
