A pivot or a shaft capable of reciprocating rotation by an external force is assembled on an electronic device (such as a mobile phone, a notebook computer, a PDA, an electronic book, etc.) so that an upper cover or a display screen can rotate to have an opening and closing function, which is a prior art. For example, taiwan patent nos. 97222022 and 98207366 provide exemplary embodiments of the present invention.

In order to provide a liftable portion (e.g., a screen) of an electronic device with more operation modes and application ranges, the prior art also discloses a structure in which a dual hinge shaft is disposed between two pivoting modules, so that the two modules can generate different operation modes or rotation angles; for example: taiwan patent No. 99211350 of "double pivot HINGE device", No. 99225737 of "double axial HINGE device", US 7512426B2 of MOBILE communication systems DEVICE WITH of synchronous HINGE, etc., all provide possible embodiments.

The conventional pivot structure is usually disposed at two sides of the pivotal connection between the display module and the body module of the electronic device (e.g., a notebook computer) in two groups in consideration of the strength of the support structure and the smoothness of the operation. Therefore, when the operation display screen or the display module rotates and lifts, the coordination of the rotating shaft is not ideal; meanwhile, the rotational freedom of the two pivot devices arranged close to the same central line is limited, so that the smoothness of the movement of the whole electronic equipment is poor in the opening or closing rotating process.

The reference data is the combination of an active joint set and a follow-up joint set; a middle linkage sheet group is arranged between two opposite joint sheets of the active joint group, and the two opposite joint sheets are provided with synchronous actuating parts which are connected with the middle linkage sheet group; the following joint group is provided with two following pieces which are arranged between two opposite joint pieces of the driving joint group; the inward end position of the relative joint sheet corresponds to the outward end position of the follow-up sheet and is combined with a shaft pin; the position of the middle linkage sheet group towards the outer end corresponds to the position of each follow-up sheet towards the inner end, and a shaft pin is combined; the plurality of active joint sets and the plurality of slave joint sets are arranged in a combined manner to form a multi-section rotating shaft structure.
