Description

Forced open password lock

This creation is about a "lock with a mandatory lock", especially a lock with a mandatory lock that combines the characteristics of a number lock and a key lock.

Thanks to the technology, the notebook computer has a lighter, thinner and smaller design. However, because the notebook computer is thin and light, it can be left in a moment, so it is often the target of thieves, especially in crowds. This situation is more common in places, or in unmanned offices. In order to improve this phenomenon, some companies have developed a notebook computer lock.

The existing notebook computer lock generally uses a key to open and close the lock. If the user accidentally loses the key, the notebook computer lock cannot be controlled and continues to be used. To prevent this from happening, there is also a number. The opening and closing number lock structure can be selected. By design, the user does not need to use the key when unlocking, and only needs to input the remembered password to achieve the effect of unlocking, and also can prevent the trouble caused by the loss of the key, however, Relying on the number to open and close the lock still has a certain risk of use. If the user accidentally forgets the password, the number lock will become unusable. At this time, it is necessary to forcibly destroy the number lock, or please The locksmith opens with a special tool, and the method of opening it takes time and effort, which will cause unnecessary use. I am troubled.

Therefore, how to develop and improve the shortcomings of the above-mentioned conventional notebook computer locks is a goal that the relevant industry needs to work hard to develop. This creator has the experience of thinking and creation, and has many years of experience. Designed, explored and tested for sample testing, and many revisions and improvements, is the creation of this creation.

Conventional notebook computers have the problem of key storage, or the shortcomings of passwords are easy to forget. If you can combine the characteristics of the two locks, you can reduce the inability to open, so that the notebook lock can be forced to open. It is the technical problem that the creator wants to solve.
