As a further improvement on the present invention, described the second rotating shaft end be positioned at the supporting frame side also fixed cover be provided with the 3rd cam, described the 3rd cam is synchronizeed with the second rotating shaft end and is rotated, the contacted surface of contact of the 3rd cam and supporting frame is provided with two boss, is smooth surface between adjacent two boss and the plane in the middle of it; On support frame as described above and the 3rd contacted surface of contact of cam corresponding two with convex platform be provided with corresponding with it two with upper groove, around 360 degree rotations, and supporting frame rotates to the several angle the function due to the Corresponding matching generation auto-closing of boss and groove to supporting frame on the second rotating shaft end.
As a further improvement on the present invention, be equipped with pad between the base on described the first rotating shaft end and the first cam, dish type shell fragment and nut; Be provided with pad between dish type shell fragment on described the second rotating shaft end and nut.
As a further improvement on the present invention, described base and supporting frame are provided with some fixed holes of fixing with product.
The invention has the beneficial effects as follows: the invention provides a kind of pair of rotating shaft rotation hub device, this kind project planning is arranged between product base and screen, except normal screen with respect to the base folding, also can be after the several angle that screen is opened, screen also can be around the second rotating shaft rotation of U-shaped pivot to arbitrarily angled, by two rotating shaft ends of U-shaped pivot coordinate rotation not only can adjusting screen and the user between distance, can also watch screen for the second people beyond the user, reach the effect of panel computer when the outside closed notebook of screen rotation.
