The key size, key position, key number, key distance, key stroke and the like are all important indexes for evaluating the usability of a mechanical keyboard, and the key stroke is a key factor affecting the use experience of the mechanical keyboard. Some mechanical keyboards designed for portability, lightness, thinness and beauty, such as a mechanical keyboard integrated on a light notebook computer, or a mechanical keyboard integrated on a leather sheath of a tablet computer, are easy to generate uncomfortable feeling when the finger tip is used as a part sensitive to a human body to receive strong recoil force for a long time due to the fact that the thinner body of the mechanical keyboard can only provide a small key stroke arrangement space and the mechanical keyboard is small in key stroke, and the user is easy to generate fatigue feeling if the user deliberately controls the striking force to reduce the recoil force. In most cases, the mechanical keyboard used by an indoor office or household computer has no portability requirement, the mechanical keyboard used under the condition has a large volume and enough key space for providing reasonable key stroke, but the designed key stroke is too long to cause soft and weak touch feeling, fatigue feeling can be generated when the keyboard is used for a long time, and the rebound time process can be caused when the keyboard is long, so that the input efficiency is reduced.
