"Universal Key", translated into English in English, is called "lily spoon", which means "a key made up of a hundred kinds of unlocking tools." It first appeared in Europe, was introduced to Asia, and then was introduced to China. It was recorded in the dictionary as early as the 1930s, but it has not been completely, accurately and professionally translated. In China, people only come into contact with TV, movies and novels. They feel very mysterious. The traditional Chinese human culture and traditional concept consciousness directly or indirectly affect people. They call it "universal key". In the lock industry, relative Professionally summarized as "technical opening."
The principle of unlocking the "universal key" is very simple. It uses steel wire, iron piece, tooth mold and many other plucking tools. It uses some very common mechanical mechanics to use the clever force to move the lock cylinder to achieve non-destructive. The purpose of opening all kinds of locks without obvious traces. Under certain conditions, using the above tools to unlock, even faster and more convenient than the original key. Different locks have different mechanisms and structures. The unlocking tools used are different, and there is no very fixed mode. Long term Come, in the contest between the "master key" and the lock, it is disappointing that the lock as a "shield" has been at a disadvantage for most of the time.
With the rapid development of modern technology, the "master key" is constantly improving and upgrading. From the earliest primary unlocking tools (such as some small steel wire, small iron pieces, etc.), it has rapidly developed to the more advanced high-pressure expansion airbags, high-frequency vibration brushes and electric electromagnetic unlockers; more advanced is superconducting soft-ray detection. Instruments, ultrasonic high-frequency detectors and the latest laser scanners use a variety of light waves, ray scanning and detection of the internal structure of the lock and easy to open. At the same time, due to various computer electronic locks, password locks, fingerprint locks and retina electronic locks, a series of locks using high-tech electronic technology, the intelligent decoder for this type of locks, the electronic code breaker is also rapid Appeared.
"Universal Key" is also very conforming to the "trend of the times" and gradually develops into a highly intelligent and foolish way. The earliest and simplest iron hooks, steel sheets, etc. can be mastered with only a short practice; today's high-intelligence unlockers do not require any technology or skill at all, and only need to be energized to generate high-frequency vibration. It is more convenient and quick to unlock at will.
These kinds of unlocking tools are freely bought and sold in the market and on the Internet, and they have become "good helpers" for unscrupulous people. The good people know nothing about this, and their awareness is still very weak, which often becomes their target. . ⊙
