Meanwhile, the elastic protrusion 41 provided on the key 40 is compressed and accumulates an elastic force by the wall of the lock hole 21, and when the elastic protrusion 41 is aligned with the wall of the first key hole 51 of the first blade 50, the elastic protrusion 41 releases the elastic force and acts on the wall of the first key hole 51 to push the first blade 50 to move relative to the cylinder core 20, so that the first blade 50 moves from the locking position (as shown in fig. 8) to the unlocking position (as shown in fig. 9), at which time the first avoiding groove 53 of the first blade 50 is aligned with the lock pin 31 and the restoring member 70 provided between the first blade 50 and the cylinder core 20 is compressed and accumulates the elastic force. When the first avoiding groove 53 of each first blade 50 and the second avoiding groove 64 of each second blade 60 are aligned with the lock pin 31, the locking mechanism 30 is in an unlocked state to allow the lock pin 31 to be inserted into the first avoiding groove 53 and the second avoiding groove 64, so that the lock pin 31 can be withdrawn from the locking groove 11 provided on the lock case 10, and thus the cylinder core 20 can be allowed to rotate relative to the lock case 10 to realize an unlocking function of the lock cylinder 100. Conversely, when the cylinder core 20 is rotated and the lock pin 31 is aligned with the lock slot 11, the elastic member 32 can push the lock pin 31 to be locked in the lock slot 11. When the key 40 is withdrawn from the lock hole 21, the first blade 50 and the second blade 60 can be reset by the elastic force of the reset element 70, so that the first blade 50 and the second blade 60 can both move to the locking position, at this time, the first abutting surface 52 of the first blade 50 and the second abutting surface 63 of the second blade 60 can both be abutted by the lock pin 31, and the locking mechanism 30 is in the locking state to prevent the lock pin 31 from being withdrawn from the locking groove 11 formed in the lock case 10, so that the lock core 20 can be prevented from rotating relative to the lock case 10, and the locking function of the lock cylinder 100 can be realized.

In addition, the present application further provides a lock, including the above-mentioned lock cylinder 100. The lockset adopting the structure can prevent a thief from finding the first blade 50 arranged in the lock liner 20 through the lock hole 21, thereby preventing the lock core 100 from being easily pried by the thief, increasing the unlocking difficulty of the lockset and further improving the safety and the anti-theft performance of the lockset.

Wherein, the tool to lock still includes the spring bolt. As shown in fig. 1 and 2, the lock cylinder 20 has a connecting end 25, and the connecting end 25 is disposed at an end of the lock cylinder 20 away from the lock hole 21. The bolt is connected to the connecting end 25, and the bolt can be driven to rotate by rotating the lock core 20 relative to the lock case 10, so as to realize locking and unlocking.

The lockset can be used for various objects such as file cabinets, drawers, doors and windows.
