In practical application, as shown in fig. 5, in order to enable the keycap 4 to be folded in the base 1, the moving plate 13 may be moved leftward, the moving plate 13 drives the bottom end of the second support 22 to move, the moving second support 22 rotates downward, and the rotating second support 22 drives the keycap 4 to descend until the keycap 4 is folded in the base 1, so that the keycap 4 can descend and be folded when not in use, thereby reducing the thickness of the keyboard; conversely, moving the plate 13 to the right causes the key cap 4 to be raised.

In this technical scheme, base 1 still includes the key cap bouncer 14 that is used for contradicting with key cap 4 and provides perpendicular ascending elasticity for key cap 4, key cap bouncer 14 is located between key cap 4 and base 1. Specifically, the key cap bouncing member 14 can be a spring sheet as shown in fig. 1 or a spring as shown in fig. 6. In practical application, after the keycap 4 is pressed, the bottom of the keycap 4 is abutted against the keycap bouncing member 14, so that the keycap bouncing member 14 stores elastic potential energy; when the key cap 4 is released and pressed, the key cap upspring piece 14 releases the elastic potential energy to upspring the key cap 4, so that the key cap 4 can be reset quickly. Or, after the key cap 4 is pressed, the first support 21 or the second support 22 rotates downwards to collide with the key cap bouncer 14 and press down the key cap bouncer 14, and after the key cap 4 is released to be pressed, the key cap bouncer 14 bouncer 21 or the second support 22 upwards to enable the key cap 4 to reset quickly.
