Abstract:
1. A dual-shaft hinge, comprising an axle housing, a pivot shaft set, a transmission mechanism and a link, wherein: said axle housing comprises a base, a first bearing portion smoothly curved from a right side of a top wall of said base in direction toward an opposing left side of the top wall of said base, a first pivot shaft chamber defined between the top wall of said base and said first bearing portion, a first gap defined between a distal end of said first bearing portion and the top wall of said base in communication with one lateral side of said first pivot shaft chamber, a second bearing portion smoothly curved from a left side of an opposing bottom wall of said base in direction toward an opposing right side of the bottom wall of said base, a second pivot shaft chamber defined between the bottom wall of said base and said second bearing portion, and a second gap defined between a distal end of said second bearing portion and the bottom wall of said base in communication with one lateral side of said second pivot shaft chamber; said pivot shaft set comprises a first pivot shaft and a second pivot shaft, said first pivot shaft comprising a first shaft body mounted in said first pivot shaft chamber of said axle housing and a first positioning tip axially extended from one end of said first shaft body, said second pivot shaft comprising a second shaft body mounted in said second pivot shaft chamber of said axle housing and a second positioning tip axially extended from one end of said second shaft body; said transmission mechanism comprises a first transmission member and a second transmission member, said first transmission member comprising a first connection hole fixedly fastened to said first positioning tip of said first pivot shaft and a first position-limit rod located at one side thereof adjacent to said first connection hole, said second transmission member comprising a second connection hole fixedly fastened to said second positioning tip of said second pivot shaft and a second position-limit rod located at one side thereof adjacent to said second connection hole; said link comprises a first position-limit hole and a second position-limit hole respectively disposed near two distal ends thereof and respectively coupled to said first position-limit rod and said second position-limit rod of said transmission mechanism, said first position-limit hole defining a first abutment portion near said second position-limit hole and a second abutment portion remote from said second position-limit hole, the distance between said first abutment portion and said second abutment portion being larger than the outer diameter of said first position-limit rod.
