Abstract
A cylindrical lock includes inner and outer chassis, inner and outer spindles, and first and second actuating members. One of the first and second actuating members is selectively and rotatably received in the outer spindle. Each of the first and second actuating members includes a limiting groove having first and second groove sections with different arcs in a circumferential direction about a longitudinal axis. A driving member is rotatably received in one of the first and second actuating members. The driving member has a leg movable in the outer spindle between first and second positions along the longitudinal axis and received in one of the first and second groove sections. A driving device is received in the inner spindle. The cylindrical lock has two modes corresponding to selective use of the first and second actuating members to provide locking/unlocking states through supply or not supply of electricity to the driving device.
