A lock comprising: a housing; a shackle having a root section and a free section; said root section disposed in said housing; said free section extending from said root section; a first lock core disposed in said housing and including a spindle capable of being driven to rotate by a key; a controlling unit disposed in said housing, defining a locking hole in a top thereof to receive said root section of said shackle, and including a block and a driving member on a bottom thereof; and said controlling unit having one end connecting with said root section of said shackle and being capable of moving linearly with said root section of said shackle along an axis of said root section; a second lock core disposed in said housing and including a movable part and a plurality of numeral wheels configured to control axial movement of said movable part; wherein said driving member of said controlling unit is engaged with said spindle so that said controlling unit is able to rotate with said spindle simultaneously to either a locking position where said block of said controlling unit is obstructed by a distal end of said movable part for disabling said linear movement of said controlling unit with said shackle or an unlocking position where said block departs from said end of said movable part for enabling said linear movement of said controlling unit with said shackle.
