Background

Early keyboards were almost all mechanical keyboards, and to be precise mechanical contact keyboards, which used electrical contact contacts as well as logos and mechanical metal springs as the spring mechanism. The keyboard has the advantages of hard hand feeling, long key stroke, quick and crisp key resistance change and very close hand feeling to a typewriter keyboard, so the keyboard is very popular at that time, and a considerable part of people still have great idea on the hand feeling of the keyboard until today. However, the two greatest disadvantages of mechanical contact keyboards are that the mechanical springs are easily damaged and the electrical contacts oxidize after a long period of use, resulting in key failure. So after the 90 s, the mechanical contact keyboard gradually exited the historical arena. Initially, an electromagnetic mechanical keyboard was substituted. The electromagnetic mechanical keyboard is still a mechanical keyboard, but it is different from the mechanical contact keyboard in that it does not rely on mechanical force to connect two electrical contacts, but rather seals the electrical contacts in a miniature potentiometer, and a magnet is placed under the keys to receive current by magnetic force.

However, the supporting angle of the outer frame of the existing computer keyboard is not adjustable, which brings inconvenience to users, and the hand support can not be folded, thereby occupying space.
