The second fixed plate is fixedly connected to the second keycap spring layer. The second keycap spring layer contains the necessary components such as the axis and spring required for the use of the keyboard. When the necessary components are connected to the keycaps, the magnetic attraction device on the sub-structure board is released by external force. By rotating the ring rod and the relative rotation of the corresponding rotating shaft one and rotating shaft two, the sub-structure board, the connecting plate and the main structure board are laid flat on the table. Then, by slightly lifting the movable keyboard, the two movable slides and the movable keyboard are moved to one side of the fixed keyboard respectively, and the movable keyboard is put down.

[0007] Preferably, when the keyboard is unfolded, the first, second, and third movable slots are on the same plane. Several of the first and second movable slots are in clearance fit with the lower half of the movable slide plate. The bottom of the movable slot is in contact with the contact plate. The movable slide plate is provided with a spring damper and a slide plate buckle. The upper half of the movable slide plate is in clearance fit with the fourth movable slot of the movable keyboard. The bottom of the movable keyboard is a fixed plate. The fixed plate is provided with a keycap spring layer. The keycap spring layer is provided with the necessary components such as the axis and spring required for keyboard use. The necessary components are connected to the keycaps. The bottom side of the fixed plate is provided with a fixed slot 1 and a fixed slot 2. When the keyboard is working, the fixed slot 1 and the fixed slot 2 are respectively in contact with the two rotating ring rods of the connecting plate. The upper contact plate of the movable slide plate will contact the bottom of the fourth movable slot, and the lower contact plate of the movable slide plate will contact the bottom of the first and second movable slots. At this time, the entire movable slide plate will be inside the first, second, and fourth movable slots, as shown in the figure.

[0008] Preferably, when the keyboard is folded and retracted, the baffle at the opening of the third movable slot and the slide plate buckle at the lower end of the movable slide plate are engaged, and the fourth movable slot and the slide plate buckle at the upper end of the movable slide plate are engaged, so that the movable keyboard is positioned above the fixed keyboard. Folding and retraction can be completed by reversing the above operation sequence.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. This new type of keyboard adopts a stacked retraction method, which stacks the movable keyboard on top of the fixed keyboard through the cooperation between the components. The keycaps of the fixed keyboard are evenly stressed, and there will be no damage to the internal components of the keyboard.

[0011] 2. The dustproof function of this new type is semi-independent from the keyboard folding and retracting function. Due to the surrounding wrapping of the outer structural plate and the sliding plate, the dustproof function of this new type will have a more stable structure and a better dustproof effect.
