A lock core includes a rotation mechanism and a clutch mechanism for separating the unlocking and opening processes of locks and prevents the lock from being unlocked destructively. The rotation mechanism comprises a plug and a plug sleeve. The clutch mechanism comprises a group of discs and a sidebar. The rotation mechanism is triggered by the clutch mechanism. Therefore the primary key for the clutch mechanism locks/unlocks the rotation mechanism. A secondary key is introduced for turning the rotation mechanism to open the lock core. The primary key and the secondary key are combined by another mechanism comprises two slots, two rivets and a spring. |
