A hinge device. The device includes an elongated main frame that extends along a first axis. The device includes an elongated pivot rod that extends along the first axis and that has a pivot end portion coupled pivotally to a stationary fixing block such that the pivot rod is rotatable axially about the first axis, and a connecting end portion connected to the main frame. A pivot unit includes an elongated pivot shaft that extends along a second axis transverse to the first axis. The pivot shaft has an upper end portion opposite to a lower end portion, which is coupled to the main frame, and projecting from the main frame. A pivot member is coupled pivotally to the upper end portion of the pivot shaft. A positioning unit is mounted on the main frame and is operable so as to prevent axial rotation of the pivot member about the second axis.
