The principle of the blade lock is to use a tooth on the key with different slope angles to rotate to align the blades with different angle changes in the lock cylinder, so as to realize a kind of lock that the lock cylinder rotates and opens.
When using, please pay attention to the insertion direction of the key: The key shank must be vertical, and the raised key (key correctly inserted into the direction mark) on the key shank can be inserted into the keyhole. After confirming that the key is fully inserted, turn the key clockwise to unlock it. Do not force the key to unlock when the key is not inserted in the end, resulting in the failure of the key stuck in the lock cylinder to pull out or twist the key. The key cannot be pulled out during rotation, and the key can only be pulled out after turning the key counterclockwise to lock it.
Because the lock core adopts the non-spring leaf structure, if the blade lock is subjected to relatively strong vibration and impact, the blade can easily rotate within a rotation range of 90 degrees, resulting in that the key cannot be inserted. Therefore, the lock box is locked when the safe and cabinet are delivered from the factory. A plastic bar similar to the key is inserted in the hole to prevent the blade from rotating freely. Please save this plastic rod. When moving, transporting safes, cabinets, or when you do not use safes or cabinets for a long time, insert plastic rods into the keyholes to prevent free rotation of the blades and prevent foreign matter from entering the keyholes.
