One preferred scheme is that a through groove matched with the extension rod is formed in the flexible balance shaft core, and guide inclined planes are arranged at the bottom and the top of the through groove.

By the above scheme, through setting up the direction inclined plane, and then do the extension rod direction, the adaptation simultaneously the change of the gesture of guide bar, work as when the extension rod is the horizontality with the middle part plane cooperation of logical groove, work as when the extension rod is followed gradually the change of gesture is made to the direction inclined plane.

The keyboard device comprises a circuit board, a shell, a plurality of standard keys and a plurality of strip-shaped keys, wherein the circuit board is packaged in the shell, the standard keys and the strip-shaped keys are connected to the circuit board, the strip-shaped keys comprise strip-shaped keycaps, mechanical switches and balance shafts, the balance seats are arranged on two sides of the mechanical switches respectively, the middle parts of the strip-shaped keycaps are connected with movable parts of the mechanical switches, and two ends of the strip-shaped keycaps are connected with the balance shafts respectively.

It is obvious by above-mentioned scheme, through setting up at mechanical switch's both ends the balance shaft, and then realize doing guarantee that balanced structure can not make a noise when rectangular shape button provides the balance, the resilience of rectangular shape key cap is by mechanical switch's resilience structure goes on. The mechanical switch is a mechanical keyboard shaft body common on the market, the standard keys are keyboard keys with standard sizes, and the strip-shaped keys are strip-shaped keys such as a space key, a shift key, a plus key of a small keyboard, a 0 key and the like. The shell is used for protecting the circuit board, and the circuit board is a circuit structure in the keyboard device.

One preferred scheme is, the top of balanced axis body is equipped with and is criss-cross connecting block, be equipped with on the rectangular shape key cap with the spread groove of connecting block looks adaptation.

According to the scheme, the connecting blocks are matched with the connecting grooves, so that the strip-shaped keycaps are fixedly connected with the balance shaft bodies.

Preferably, the bottom of the balance seat is provided with a connecting hook matched with the circuit board.

According to the scheme, the balance seat is clamped and fixed with the circuit board through the connecting hook.
