Abstract

The invention relates to a mechanical keyboard with keys capable of being retracted and overlapped. The keyboard is composed of a shell, keycaps, key shafts, key bodies, retractable rods, an adjusting frame and a restraining plate. When the keyboard is not used, all the keys of the keyboard can be retracted into the shell to be arranged compactly in an overlapped mode. When the keyboard is used, all the keys of the keyboard can stretch out of the shell and expand to be used by users. Due to the fact that hollow grooves are formed in the keycaps of the keys of the keyboard, the key shafts of other keys can be clamped in the grooves, so that the keycaps can be placed in an overlapped mode with one above another when all the keys are retracted into the shell, and then occupied space is small when the keys of the keyboard are retracted into the shell. The mechanical keyboard with keys capable of being retracted and overlapped meets the requirement of portable devices for portability of keyboards.
