1. A hinge connectable with two housing parts of a flexible electronic device to allow opening and closing of the housing parts, comprising:
a mounting seat extending in a lengthwise direction and having two lengthwise edges at two opposite sides of a central line, said mounting seat having two first arcuate slots which extend from the central line toward said lengthwise edges, respectively;
two rotary units connected with said mounting seat at said two opposite sides of the central line, respectively, said two rotary units being shiftable between an unfolded state and a folded state, each of said rotary units including
a linking member having a linking body which has a plate supporting surface, a first arcuate rail which extends from said linking body and which is slidably engaged with a respective one of said first arcuate slots, and a second arcuate rail which extends from said linking body away from said first arcuate rail,
a rail sliding block having a block body which has a housing supporting surface for one of the housing parts to be attached thereto, a second arcuate slot which is formed in said block body and slidably engaged with said second arcuate rail, and an outward inclined sliding portion which is formed on said block body and opposite to said second arcuate slot in the lengthwise direction,
a rotating bracket pivotally connected with said mounting seat, and having a bracket body and an inward inclined guiding portion which extends from said bracket body to terminate at a terminal end, said inward inclined guiding portion having an inward inclined block, an inward guideway which is formed on said inward inclined block, and a first guiding slope which is formed on said terminal end of said inward inclined guiding portion and adjacent to said inward guideway, and
an interposed sliding member interposed between said rail sliding block and said rotating bracket, said interposed sliding member having an inward inclined sliding portion which is slidably engaged with said inward inclined guiding portion, and an outward inclined guiding portion with which said outward inclined sliding portion is slidably engaged, said inward inclined sliding portion having an inward inclined slide rail with which said inward inclined block is slidably engaged, an inward key which is disposed on said inward inclined slide rail and is guided in and slidable along said inward guideway, and a second guiding slope which is formed on said second inward key and which is slidably engaged with said first guiding slope to guide slidable engagement of said inward key in said inward guideway,
wherein, during the shifting of said rotary units from the unfolded state to the folded state, said rail sliding block is slid relative to said second arcuate rail, and is turned relative to said mounting seat through sliding of said interposed sliding member relative to said rotating bracket; and
two lateral support plates, each securely connected with and supported on said plate supporting surface to be moved with said linking member, wherein, in the unfolded state of said rotary units, said plate supporting surfaces of said linking members are flush with each other and in a horizontal state, and said lateral support plates are disposed to cover said mounting seat, and wherein, in the folded state of said rotary units, said plate support surfaces are inclined to each other in a direction away from said mounting seat to bring said lateral support plates to be inclined to each other, and said housing supporting surfaces of said rail sliding blocks are disposed to face and to be parallel to each other and to be in a vertical state.
