Abstract
The invention provides a lock cylinder capable of rapidly transforming keys, as well as a method for rapidly transforming keys of the lock cylinder. A movable lock core and an adjusting block are arranged in a lock case; the adjusting block is selectively fixed by a fastening piece in the lock case; a plurality of lock bead sets are arranged in the lock case; a plurality of clutch sets are arranged in the lock core; and tooth position plates of the clutch sets are controlled by the adjusting block to clutch corresponding tooth position blocks. When the lock cylinder transforms keys, a user only needs to use a first key to rotate the lock core and the adjusting block, so as to ensure that: after the adjusting block is fixed, by means of the axial movement of lock core reset, the tooth position plates of the clutch sets are driven by a guide part of the adjusting block to make radial movement and to separate from or engage the tooth position blocks; after the first key is pulled out, a second key is inserted to rotate the lock core and the adjusting block, which leads the tooth position plates to engage the tooth position blocks again and resets a tooth position state according to the second key. Therefore, the lock cylinder can rapidly transform the keys through convenient operation without the assistance of other tools.
