Key
is important thing in our life, we use key to lock our door, so that bad man
can not get in, our possession will not lose, we also use car ignition key
switch to ignite our car ,we use our motorcycle ignition key switch to start
our motorcycle. The function of key switch, we can have a good dream at night,
don’t need worried about our car or motorcycle stolen.
There
are also some key
switch pattern used to as a art, we can use it to add some beauty to
our things, it can seems very interesting.
But
do you know the history of key? Primitive man lived a burrowing life, for
security, sometimes to push boulders to block the entrance; it is not the thief
but wild beasts. The emergence of private system, the thief appeared, and the
lock was born. As early as three thousand years ago, China has a lock. However, the
earliest lock without authority, just as tigers and other ferocious animal
shape, want to put the thief away, can only be said to be a symbolic lock.
It
is said that Lu ban was the first to lock is arranged on the bodies of the
people. The unearthed relics and records of the situation, the ancient locks on
elastic work two plate springs. Until now, this spring is still in use. In
foreign countries, the ancient Greeks had found a highly reliable lock, but the
key is larger, to carry on the shoulder, it is difficult to popularize in the
general family. The ancient Indians made another bird shaped "fans"
lock, key hole hidden in the wings can jitter. The rise of modern lock first in
eighteenth Century by the British invented "welding fishing lock". We
make extensive use of the marble lock, is an American Nick Ruth invented in
1860, and the invention of the lock and key than to later, the ancient
Egyptians is the world's earliest use of keys.
