Super B-class lock cylinder (Class C)

The shape of the super b-class lock core key is a single-sided blade inner milling slot or an outer milling slot key. The lock cylinder type is a side cylinder lock core; it can not be technically opened by the Ministry of Public Security for 270 minutes, and the regional mutual opening rate is almost zero. The structure of the marble is locked by the double row of blades and the V-shaped side column; if the lock cylinder is opened with a strong twisting tool, the internal core of the lock cylinder is broken, and the self-explosion is locked, resulting in failure to open.
