Abstract

See full text

A door lock (10) includes a driving device (30) having an outer spindle (36) and an outer handle (38) mounted to the outer spindle (36). A mounting member (56) is rotatably mounted in a compartment (46) of the outer handle (38). A positioning member (72) is movably received in a groove (54) of the outer handle (38). When a lock core (74) disengages from the mounting member (56), the mounting member (56) cannot move along a longitudinal axis but can pivot about a pivotal axis relative to the outer handle (38) to change a positional relationship between first and second holes (64, 66) of the mounting member (56). After the lock core (74) engages with the mounting member (56), the mounting member (56) cannot pivot about the pivotal axis relative to the outer handle (38).
