ABSTRACT:
The hinge device comprises a rotating shaft, a cylinder and a liner tube. The cylinder contains a cylindrical body having a passage therein, a fixing member and a positioning groove. The liner tube includes at least two pieces of liner portion with a hole therein, or it includes a liner member having a hole therethrough. A positioning flange is projected on the end of the liner tube so as to engage with the positioning groove. At both sides of the liner tube are formed curved portions respectively. While a shaft portion of the rotating shaft is pivotally inserted into the hole, between the curved portion and the cylindrical body is left some space for expansion; therefore, as the rotating shaft turns clockwise or counterclockwise, the rotation of the present invention is made smoothly which further results in hard wear and durability.
