Dual-use lock whose unlocking numeral combination can be traced after having been forgotten

A dual-use lock whose unlocking numeral combination can be traced after having been forgotten, comprising

• a male member securely connected with one end of a cable;
• the male member having spaced teeth along a rod portion thereof;
• a female member securely connected with other end of the cable;
• a spindle for allowing insertion of the rod portion of the male member therein;
• the spindle being inserted in the female member at a tail end thereof;
• a plurality of dial assemblies arranged around the spindle;
• each dial assembly including both a dial with numerals thereon, and a tooth dish releaseably engaging the dial to be capable of turning together with the dial;
• the tooth dishes each having a gap on an inward edge;
• the gaps of the tooth dishes together being capable of forming a passage for allowing separation of the male member from the spindle when the dials are turned to an unlocking orientation;
• the tooth dishes being capable of stopping the teeth of the male member to prevent separation of the male member from the spindle when the dials are turned away from the unlocking orientation;
• and
• an auxiliary lock member fitted to the female member for releaseably securing the spindle to the female member, thereby being operable with a key thereof to become unlocked for both the male member and the spindle together to become separable from the female member while the male member is secured to the spindle by the tooth dishes;
• the auxiliary lock member having a recess, and an engaging portion next to the recess;
• the auxiliary lock member detaining the spindle when the engaging portion thereof is fitted in a securing recess of the tail end of the spindle;
• the auxiliary lock member releasing the spindle when the recess thereof opposes the securing recess of the tail end of the spindle.
