In this manner, lock core 600 may also simultaneously control deadbolt assembly 400 and safety tongue assembly 300 for simultaneous unlocking.

For example, when the key cylinder dial 620 rotates clockwise, the second transmission member 513 may be driven to rotate clockwise, so as to drive the first transmission member 511 to rotate counterclockwise, the first transmission member 511 drives the dial member 521 to rotate clockwise, and at this time, the first dial portion 5211 drives the latch bolt assembly 400 to move from the extended position to the retracted position, thereby unlocking the latch bolt assembly 400. Meanwhile, the second striking portion 5212 drives the latch transmission mechanism 530 to move, so as to drive the latch assembly 300 to move from the extended position to the retracted position, thereby unlocking the latch assembly 300.
