1. A hinge comprising:
a base frame unit including a base seat which is elongated in a front-rear direction;
two rotatable axle units disposed on said base seat and spaced apart from each other in the front-rear direction, each of said rotatable axle units including a receiving seat which is disposed on said base seat, and two hinge shafts which are spaced apart from each other in a left-right direction that is transverse to the front-rear direction and each of which is rotatably disposed to said receiving seat about a shaft axis parallel to the front-rear direction;
two synchronizing units respectively disposed to said rotatable axle units to make synchronous rotations of said hinge shafts in opposite rotational directions;
two movable bracket units pivotably disposed to said base seat and opposite to each other in the left-right direction, each of said movable bracket units including a base plate which is turnably disposed to said base frame unit and which is elongated in the front-rear direction, two rotary blocks which are non-rotatably sleeved on said hinge shafts, respectively, and two movable plates which are connected with and movable relative to said rotary blocks, respectively, and each of which has a distal end remote from said respective hinge shaft; and
two guiding bracket units respectively disposed on front and rear ends of said base seat, each of said guiding bracket units including a male arm which is securedly connected with one of said movable plates of one of said movable bracket units, a female arm which is securely connected with one of said movable plates of the other one of said movable bracket units and opposite to said male arm in the left-right direction, and a plurality of guiding connecting members which are interposed between said male arm and said female arm and which are adjoined with each other in the left-right direction, each of said guiding connecting members having a body which extends in the left-right direction to have first and second end surfaces and which has a sliding groove that extends from said second end surface toward said first end surface, and a protrusion which extends outwardly from said first end surface and which is movably engaged in said sliding groove of an adjacent one of said guiding connecting members such that each of said guiding connecting members is angularly movable relative to said base seat between a first position, where said protrusion is fully engaged in said corresponding sliding groove so as to permit said guiding connecting members to be close intimately to each other, said male and female arms extend in an up-down direction that is transverse to both the front-rear direction and the left-right direction, and said movable plates extend also in the up-down direction and proximate to said corresponding hinge shafts to have the distal ends close to each other, and a second position, where said protrusion is partly engaged in said corresponding sliding groove so as to permit said guiding connecting members to be remote from each other, said male and female arms extend in the left-right direction, and said movable plates also extend in the left-right direction to have said distal ends remote from each other, and are moved relative to said rotary blocks to be distal from said corresponding hinge shafts, said body of each of said guiding connecting members having an abutted block which is formed in said sliding groove, said protrusion having an abutting portion which faces and abuts against said abutted block of said adjacent guiding connecting member in the second position to prevent removal of said protrusion from said sliding groove.
