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 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 synchronizing units respectively disposed to said rotatable axle units to make synchronous rotations of said hinge shafts in opposite rotational directions, each of said synchronizing units including a synchronizing seat which is disposed on said base seat, a first gear member which is rotatably mounted to said synchronizing seat about a gear axis parallel to the left-right direction and which extends in the left-right direction to have two end surfaces that are in form of bevel gears, and two second gear members each of which has a bevel gear portion that meshes with a respective one of said end surfaces of said first gear member, and a first axial portion that extends from said bevel gear portion along the shaft axis and that is non-rotatably fitted to a respective one of said rotary blocks such that rotations of said hinge shafts at one side of said base seat result in rotations of said rotary blocks and said second gear members at said one side of said base seat, and bring in rotations of said second gear members, said rotary blocks and said hinge shafts at the other side of said base seat so as to make the synchronous rotations of said hinge shafts in opposite rotational directions.
