Description of the Invention: [Technical Field] The present invention relates to a hinge for use in a folding electronic product such as a notebook computer or a mobile phone, and more particularly to a pivot device having six friction interfaces. [Prior Art] In a folded electronic product towel, it is necessary to pivotally connect a base (e.g., a keyboard or a button) and a rotating portion (e.g., a screen) to achieve a foldable function. In the common pivoting structure, after the shaft is passed through the base, the end of the shaft is locked with a nut, and the group of the discs composed of a plurality of disc-shaped elastic pieces is fixed between the pumping and the base. . The base is connected to the base of the folding electronic product, the rotating shaft is connected to the rotating portion, and the elastic group provides an axial pressing force. In order to position the rotating portion of the folded electronic product at an opening angle with respect to the base, a part is also provided between the base and the shrapnel to create a friction interface. A typical friction interface is formed by a fixed positioning spacer and a sub-carrier adjacent to the base, and a fixing plate disposed between the rotating shaft and the rotating shaft; and two positioning surfaces of the fixing plate and the positioning spacer and the auxiliary The carrier contacts to form a friction interface such that the folded portion of the folded electronic product can be positioned at an opening angle relative to the base. Conventional such hubs have limited support for the entire hinge to open due to the fact that there are only two friction interfaces. If the opening support force is to be increased, it is necessary to increase the diameter of the hinge to increase the area of the friction interface; however, the tightening requirements for the portable folding electronic product are rather unfavorable. 5 1310811 SUMMARY OF THE INVENTION Accordingly, the present invention provides a hinge having a multi-friction interface, which utilizes four fixing plates provided in a pivoting device to generate six friction interfaces, so that the hinge of the same diameter can be improved. The friction area can achieve the effect of generating large torque in a small space under the force of the same shrapnel group. Hereinafter, the structure and effect of the present invention will be described in detail based on the embodiments shown in the drawings. [Embodiment]
