Abstract

The utility model discloses a variant-bit blade type antitheft lock, including lock body, lock tongue component, and blade group stacked with the lock tongue component. Each blade of the blade group includes mutually chimeric two parts: the coding blade and the variant-bit blade. The lock body is arranged with a coding alignment device used to push each blade to the mutual chute centerline and a separating device used to separate the coding blade and the variant-bit blade. After the separation of the coding blade and the variant-bit blade, the new teeth key is used to adjust the variant-bit blade in order to change the chimeric relation between the variant-bit and the coding blade, so that the new combination can match the new key teeth. After the change, the original key teeth can not open the changed blade lock. Because the chimeric relationship between the variant-bit blade and the coding blade closely relates to the teeth shape of the new key, through changing the chimeric relationship between the coding blade and the variant-bit blade, the same lock can match with different key teeth according to the need.
