1. A hinge adapted to be connected between two casings, and comprising:
a fixed seat including two seat bodies that are connected side by side along a first direction, each of said seat bodies having an inner side surface that faces the other one of said seat bodies and that is formed with two symmetric tracks arranged along a second direction perpendicular to the first direction; and
two symmetrically-disposed support modules being arranged along the second direction, flanking and movably connected to said fixed seat, and being convertible with respect to each other between an unfolded state and a folded state, each of said support modules including
a pivot guide unit that is pivotally connected to said fixed seat, and that has a bearing surface facing outwardly, and an oblique guide rail extending obliquely with respect to said bearing surface, and
a sliding unit that has
a sliding pivot arm having a sliding shaft, an orthogonal guide portion that is spaced apart from said sliding shaft along the second direction, and an arm body that extends along the second direction and that is connected between said sliding shaft and said orthogonal guide portion, said sliding shaft extending along the first direction and being movably received in a pair of said tracks of said seat bodies that are aligned with each other along the first direction, such that said sliding pivot arm is slidable with respect to said seat bodies of said fixed seat and is pivotable about said sliding shaft, and
a slide block adapted to be connected to said pivot guide unit and a respective one of the casings, and having a block body, a slide slot that is formed in said block body for receiving said orthogonal guide portion and a portion of said arm body of said sliding pivot arm, and an oblique sliding portion that is formed on said block body and that is movably engaged with and complementary in shape with said oblique guide rail of said pivot guide unit, said slide block being slidable with respect to said sliding pivot arm along a direction perpendicular to said bearing surface via engagement between said orthogonal guide portion and said slide slot, and being slidable with respect to said pivot guide unit along a direction oblique to said bearing surface via engagement between said oblique guide rail and said oblique sliding portion;
wherein when said support modules are converted from the unfolded state to the folded state, said sliding pivot arm of each of said support modules slides and pivots with respect to said fixed seat such that said sliding shafts of said sliding pivot arms of said support modules move away from each other, and said orthogonal guide portions of said sliding pivot arms of said support modules move towards each other, and said oblique sliding portions of said support modules slide respectively on said oblique guide rails of said pivot guide unit, so that said slide blocks of said support modules move toward each other.
