Furthermore, the pin tumbler groove comprises a first pin tumbler groove arranged in the lock cylinder and a second pin tumbler groove arranged in the lock cylinder sleeve and matched with the first pin tumbler groove, and the second pin tumbler groove is radially arranged from inside to outside.

The lock with the spiral twist-shaped lock head assembly is characterized in that the lock head assembly is detachably arranged in the lock.

The utility model has the advantages that: 1. the torsional strength of the key is improved, and the key is effectively prevented from being twisted and broken; 2. the quantity of the secret keys can reach more than million levels, the technology is effectively prevented from being started, and the safety performance is high; 3. the lock can be used for various occasions such as padlocks, traffic locks, door locks, safe cases and the like, and has wide applicability; 4. the lock head is detachably arranged in various locks, so that the maintenance performance and the application range of the locks are improved, and the safety is better.
