An outside handle assembly of a lock includes an outside lever handle, an outside handle spindle secured to the outside lever handle to rotate therewith and including a first slot defined in a periphery thereof, and an actuating spindle mounted in the outside handle spindle and operably connected to a retractor. The actuating spindle includes a second slot aligned with the first slot of the outside handle spindle. A catch is mounted in the actuating spindle and has a first end pivoted to the actuating spindle and a second end. A tapping plate is slidably mounted in the actuating spindle and connected to the tail piece to move therewith. When the lock is in an unlocked status, the outside handle spindle and the actuating spindle rotate synchronously, as the second end of the catch extends through the second slot of the actuating spindle into the first slot of the outside handle spindle. When the push button is pressed, the tapping plate is moved to engage with a hooked portion of the first end of the catch and thus pivots the catch during the sliding movement of the tapping plate. The second end of the catch is thus disengaged from the first slot of the outside handle spindle to allow free rotational movement of the outside lever handle.
