A synchronizing hinge includes a rotating module and a bracket plate unit. The rotating module includes two support units pivotably mounted to a base seat. Each support unit has a first support piece, a second support piece pivotably connected with the first support piece, and a moving axle extending through the first support piece and an arcuate slot of the second support piece and movably received in a moving slot of the base seat. The bracket plate unit includes two first bracket plates securely connected with the first support piece, and two second bracket plates securely connected with the second support piece. The support units and the bracket plate unit are rotatable between an initial position where the first bracket plates are flush with the second bracket plates, and a terminal position where the first bracket plates are inclined relative to the second bracket plates by an inclined angle.

A rotating shaft device includes a base, a rotation member, a slide member, a supporting member, and a linkage unit. The rotation member is rotatable relative to the base between a first position and a second position. The slide member is slidable relative to the base. The supporting member is pivotable relative to the base between an initial position and a supporting position. The linkage unit is convertible between a folded state and an expanded state. When the rotation member is in the first position, the linkage unit is in the folded state and the supporting member is in the initial position. When the rotation member is rotated to the second position, the slide member is urged by the rotation member to slide and to convert the linkage unit into the expanded state, and the supporting member is urged by the linkage unit to pivot to the supporting position.

Rotating shaft device

A rotating shaft device includes a base, a rotation member, a slide member, a resistance-providing member, a supporting member, and a linkage unit. The rotation member is rotatable relative to the base between a first rotation position and a second rotation position. The slide member is slidable relative to the base between a first slide position and a second slide position. The resistance-providing member prevents the slide member from moving toward the first slide position when the slide member is in the second slide position. The supporting member is movable relative to the base between an initial position and a supporting position. The linkage unit is convertible between a folded state and an expanded state. When the rotation member is in the first rotation position, the slide member, the linkage unit, and the supporting member are respectively in the first slide position, the folded state, and the initial position.
