Abstract
An outer operating device for a door lock includes a mounting plate mounted to an outer side of a door. A driving wheel is pivotably mounted in a mounting seat fixed to the mounting plate. A driving member is pivotably mounted in the mounting seat and meshes with the driving wheel. A distal end of the driving member is operably connected to a latch of a latch device. A handle is pivotably mounted to the mounting seat and includes a lever. A movable block is slideably received in the driving wheel and includes a notch. When a pressing end of the lever is not aligned with the notch of the movable block, the latch can be retracted to an unlatching position by pivoting the handle. When the notch is aligned with the notch of the movable block, the latch cannot be retracted by pivoting the handle.
