[0013] This utility model provides a smart lock that prevents damage to the lock cylinder. By exploiting the fact that thieves are unfamiliar with the internal structure of the smart lock and the obstruction of the blocking plate, thieves cannot damage the lock cylinder through the keyhole. When the homeowner needs to open the smart lock through the keyhole, pressing the push plate on the back of the locking frame moves the push rod, which in turn moves the locking lever away from the slot on the fixed post. This moves the blocking plate to the right, exposing the keyhole for unlocking. After unlocking, the fixed post is reinserted into the locking frame, and releasing the push plate allows the locking lever to be reinserted into the slot in the fixed post by the spring force of the return spring a, ensuring the stability of the blocking plate. The push plate's concealed design, located on the back of the locking frame, prevents thieves from damaging the lock cylinder without affecting the homeowner's normal use.
