A controlling assembly for a locking device includes a latch bolt adapted to be engaged with the axle and rotatably extending out of the casing, the latch bolt having a threading formed on a free end of the latch bolt, a dial ring adapted to be movable and rotatable relative to the axle and a clutch device provided to selectively engage the dial ring and the latch bolt. When the latch bolt is engaged with the dial ring and the locking device is in an unlocked status to allow the axle to move axially inside the casing, rotation of the dial ring is able to drive the latch bolt to rotate simultaneously so that the latch bolt is able to threadingly engage with an object to be protected.
