ABSTRACT:
An outside spindle is mounted to an outside handle of a lock to turn therewith. An outer end of the outside spindle includes a slot and at least one engaging piece formed thereon. A core retainer is securely mounted to the outer end of the outside spindle. The core retainer receives and positions a lock core interchangeably mounted in the outside handle. The core retainer includes a longitudinal slot aligned with the slot of the outside spindle, with the lock core extending into the slot of the outside spindle and the longitudinal slot of the core retainer. The core retainer further includes at least one positioning opening for securely receiving the engaging piece of the outside spindle, providing the lock core with a pulling-resisting effect in the axial direction.
