What is the free handle of the smart lock?

The so-called free handle in the fingerprint lock is actually the handle will become free after unlocking with the correct unlocking method, while the free state means the state of being unstressed, although the handle is still level with the ground, but if the handle is held down The pressure is not laborious. This is the free handle that people often say, that is, the safety handle. The word is only relative to the handle type fingerprint lock. There is no "free handle" in the push-pull handle.

The role of the free handle (safety handle) can be broadly divided into the following aspects:

1 Prevent violent unlocking from causing damage to the internal parts of the fingerprint lock. This is useless for normal people, because normal people will not know that the door is locked and it is hard to press the handle to open the door. However, it is very useful for some people with obsessive-compulsive disorder or ulterior motives. The design of the free handle will give them a feeling of brute force on the cotton, so that there will be no damage to the fingerprint lock and the normal operation of the fingerprint lock. .

2 anti-lock is more convenient. With this design, the user only needs to gently lift the handle to unlock the fingerprint lock, which is safe and saves time and effort.

3 If the chip lock in the lock body of the fingerprint lock is fast enough, and the processing capacity is strong enough, it can also be combined with the free handle to achieve the anti-tailing effect - verify the unlock mode → press the handle into the door → lift the handle to lock, this process can be fast enough Let the illegal molecules behind it be multiplied. After the corresponding electronic lock is unlocked, it usually takes 5~10s to re-lock. During this period, if other people press the handle to open the door again, it will be dangerous if they encounter a bad person.
