Claim Text:
1. A shift-brake device of a twin-shaft hinge, at least comprising: a locking assembly comprising a base seat, a pressing plate and two shaft sleeves, in which the base seat is configured with two through holes, the pressing plate having a middle section pivotally connected to a middle section of the base seat is configured with two sleeve holes corresponding to the two through holes of the base seat respectively, ends of the two shaft sleeves are respectively configured with sleeve portions capable of entering the two sleeve holes of the pressing plate, the two shaft sleeves are respectively circumferentially configured with circular flanges having concave portions, parts of external circumferences of the two sleeve holes of the pressing plate are respectively configured with convex portions that are correspondingly fitted to the concave portions of the two shaft sleeves, and the two shaft sleeves are respectively configured with coupling holes in an extension direction of the two through holes of the base seat and the two sleeve holes of the pressing plate; and a first pivot shaft and a second pivot shaft parallel to the first pivot shaft, in which the first and second pivot shafts have ends respectively, sequentially and penetratingly arranged in the two through holes of the base seat, the coupling holes of the two shaft sleeves and the two sleeve holes of the pressing plate so that the first and second pivot shafts are respectively connected to the base seat, the pressing plate and the two shaft sleeves of the locking assembly and the first and second pivot shafts are respectively, synchronically pivoted and linked with the two shaft sleeves of the locking assembly, wherein the first pivot shaft is connected to a first shaft sleeve of said two shaft sleeves and the second pivot shaft is connected to a second shaft sleeve of said two shaft sleeves, so that when the first pivot shaft is pivoted, the connected first shaft sleeve of the locking assembly is synchronically driven when the first pivot shaft is pivoted and the circular flange of the first and second shaft sleeve is utilized to push against the convex portion of the pressing plate to incline the pressing plate toward the second shaft sleeve so that the convex portion of the pressing plate which is located between the second shaft sleeve and the pressing plate is correspondingly embedded into the concave portion of the shaft sleeves to limit pivoting of the second shaft sleeve.
