In summary, the key of the present invention is mainly designed by arranging the balance bar, and embedding the embedded portion of the balance bar on the support plate, so that the first connecting portion and the second connecting portion of the balance bar are respectively connected to two ends of the key, thereby implementing an embedded balance bar structure, improving the overall structural strength of the key, improving the stability of the "X" structure, ensuring the balance of the key under stress, and effectively preventing the key from being prone to skewing, key jamming, etc. during the key action, and having better operation feel during the key action; secondly, the balance bar of the keyboard with the embedded balance bar structure can be relatively fixed on the support plate, so that the balance bar can be assembled automatically and the whole set of keys can be assembled automatically, and the production efficiency can be greatly improved; and, through setting up the first fulcrum on the first support as the slip fulcrum, the second fulcrum on the second support sets up to fixed fulcrum, and make the slip fulcrum rotatable and slidingly connect first supporting part, the second supporting part is connected to fixed fulcrum only rotatablely, thereby make it realize the unilateral slidingtype setting of X structure, single-shear type "X" structure has been realized, the size of button has been reduced, and two supports need not to slide simultaneously, make the structure more stable, when two supports homoenergetic slide can not appear, because the user acts on the power point's of button difference, and lead to two supports atress inequality and the phenomenon that the button leaned towards the equidirectional slope appears, and the phenomenon that the fulcrum of two supports received each other influence can not appear.
