  • This design which judges that the lock core 120 rotates to the unlocked position or the locked position, thereby triggering the action of the return device, has its drawbacks. This is because when the lock core 120 moves to an unlocked or locked position that cannot continue to rotate, the key 400 has a tendency to rotate because it is driven by the key transmission mechanism 310; on the other hand, due to the structural design of the unlocking device itself Therefore, the key 400 cannot rotate; therefore, the torque acting on the key 400 will cause some damage to the key 400 itself.

  • the lock core 120 will not return to its natural position depending on the function of the return device. This is because, when the user needs to remove the key 402 after completing the door opening operation, the user must manually rotate the key 402 to the natural position before the key 402 can be removed.
