Thereby, the distance between the contact points shortens the force arm of the first support arm and the second support arm, so as to reduce the deformation and shaking of the button when the button is pressed, thereby improving the sensitivity of the button. Preferably, the rotating shaft and the pivot hole are both non-circular, so that the respective sleeves of the sleeve and the pivot hole are not located on a circular arc of the same arc. Preferably, the cross section of the rotating shaft is slightly inverted with an isosceles triangle and has two waist sides 'and the angle between the two waist sides of the rotating shaft is greater than 9′, and the jack corresponds to the waist of the rotating shaft. The side has two bottom edges, and the angle between the two bottom edges is greater than the angle between the two waist sides, and the rotating shaft has a top edge connecting the two waist sides, and the pivot hole has two top faces corresponding to the two The top surface is abutted against the top edge of the 'rotating shaft' in different pivoting directions, whereby the rotating shaft and the frame hole may have more than two contact points during pivoting. The detailed features and advantages of the present invention are described in detail below in the embodiments, which are sufficient to enable any skilled person to understand the technical contents of the present invention and implement the present invention, and according to the content disclosed herein, the scope of the patent application and ® No, anyone familiar with the art can easily understand the purpose and advantages of this creation. [Embodiment] The preferred embodiment of the present invention will be described in detail below with reference to the drawings. Please refer to Figure 1 to Figure 4, Figure 1 is the external 5 M381116 view of the keyboard of this creation; Figure 2 is the cross-sectional structure diagram of the button of this creation; Figure 3 is the part of the hinge structure of the creation Magnified view; Figure 4 is a schematic diagram of the state of use of this creation. The keyboard 1 of the present invention is constructed by arranging a plurality of buttons 2 in a casing 10. Each of the buttons 2 is composed of a bottom plate 20, a keycap 3, a support mechanism 4, and an elastic member 5. In actual implementation, the bottom plate 20 of each button 2 can be integrated and disposed in the casing 10 of the keyboard 1. A first connecting portion 21 is formed on the surface of the bottom plate 20. In the embodiment, the first connecting portion 21 includes a first pivoting portion 211 and a first sliding slot 212 to respectively connect with the supporting mechanism 4. . The bottom surface of the key cap 3 has a second connecting portion 31 corresponding to the first connecting portion 21 . In the embodiment, the second connecting portion 31 includes a second pivoting portion 311 and a second sliding slot 312 . Connected to the support mechanism 4 respectively. The support mechanism 4 is composed of a first support arm 41 and a second support arm 42. The first support arm 41 has a shaft portion 411, 412 at both ends, and the two shaft portions 411, 412 The second pivoting portion 311 of the keycap 3 and the first sliding slot 212 of the bottom plate 20 are respectively pivoted; the two ends of the second supporting arm 42 also have a shaft portion 421, 422, respectively, and the two shaft portions 421 The 422 is pivotally disposed on the second sliding slot 312 of the keycap 3 and the first pivoting portion 211 of the bottom plate 20, so that the keycap 3 can be displaced upward and downward relative to the bottom plate 20. The first support arm 41 and the second support arm 42 are pivotally connected to each other in a middle portion. The first support arm 41 has a rotating shaft 43 , and the second support arm 42 has a pivot hole 44 corresponding to the pivot 42 . The rotating shaft 43 is pivotally disposed in the pivot hole M381116. The cross section of the rotating shaft 43 is not circular, but has an inverted isosceles•triangle and has two waist sides 431, and the angle 两1 of the two waist sides 431 The pivot hole 44 has two bottom edges 441 corresponding to the two waist sides 431 of the rotating shaft 43, and the angle 0 2 of the two bottom edges 441 is greater than the angle 0 1 of the two waist sides 431, and the rotating shaft 43 has a top edge 432 connecting the two waist sides 431, the frame hole 44 has two top surfaces 442 corresponding to the top edge 432, and the angle 0 3 between the two top surfaces 442 is less than 180°, so that the top surface 442 can be used to abut the top edge 532 of the rotating shaft 43 in different pivoting directions, thereby causing the rotating shaft 43 and the pivoting hole 44 to have more than two contact points T during pivoting, and each contact The point T is not on the arc of the same arc. Referring to FIG. 4, when the user presses the keycap 3, the first support arm 41 and the second support arm 42 of the support mechanism 4 (ie, the scissors mechanism) are relatively frame-rotated, because the rotating shaft 43 of the present invention The pivot hole 44 is not circular, so the contact point T between the rotating shaft 43 and the pivot hole 44 is changed during the pivoting process. When the state shown in FIG. 4 is reached, the rotating shaft 43 is The pivot hole 44 has three contact points T, which are respectively located at the bottom end of the rotating shaft 43 and the bottom end of the pivot φ hole 44, between the waist 431 and the bottom 441 of the right side of the rotating shaft 43 in the figure, and the rotating shaft 43. Between the top edge 432 and the top surface 442 of the left side of the pivot hole 44, the distance between the respective shaft portions 411, 412, 421, 422 to the respective contact points T is relatively short, that is, the force The length of the arm is shortened compared to the structure described in the prior art, so that the amount of deformation that may occur in the first support arm 41 and the second support arm 42 can be effectively reduced, thereby reducing the problem of button shake to improve the sensitivity of the button.
