Abstract
A lockset and a door lock belong to the technical field of door locks. The lockset includes a drive shaft. Two ends of the drive shaft are respectively connected to handle assemblies. The handle assembly includes a handle and a lock seat. A linkage mechanism is provided between the handle of one of the handle assemblies and the drive shaft, and is configured to lock the handle and the drive shaft such that the handle and the drive shaft are circumferentially fixed. The other handle assembly is provided with a switch mechanism for driving the linkage mechanism to lock or unlock. When the switch mechanism drives the linkage mechanism to unlock, the handle is rotatable independently relative to the drive shaft. Therefore, the safety performance of the lockset is improved, and the service life thereof is extended.
