The invention relates to a hardware lockset, in particular to a burglary-resistance lock. The burglary-resistance lock is mainly composed of a lock frame, a lock core and a damping device. The burglary-resistance lock is characterized in that the lock core is arranged in the lock frame, and the damping device is arranged between the lock frame and the lock core. When the lock is opened normally, a key is inserted to rotate, after the lock core rotates by 90 degrees, an inner core of the lock core can quit, and the unlocking is achieved; when locking is performed, a disk brake lock is clamped on a disk brake plate, and only does the inner core need to be pressed. The burglary-resistance principle is that when the lock is pried by the use of a violent tool, since a tumbler in the lock core is not matched with the key, rotation can not occur between the lock core and the inner core, although the lock can be screwed by the use of the violent tool, at the time, the damping device between the lock core and the lock frame plays a protection effect, when the violence exceeds the resistance set by the damping device, the lock core can rotates with the violent tool, in this way, rotation can not occur between the lock core and the inner core, the lock can not be opened, and a vehicle is safe.
