As one embodiment, the master page and the child page are in a nested structure, and the child page is nested in a through hole of the master page. The base part of the fixed core is positioned in the pipe hole of the sub-page and extends into the pipe hole of the main page, the rotating part of the fixed core is positioned at the upper end and the lower end, and the rotating part is in contact connection with the pipe hole of the main page through the needle roller bearing. Through needle bearing, can reduce frictional force, the hinge is got up more smoothly quieter.

As a further preferred aspect, the intermediate portion of the stationary core is reduced in diameter to further reduce friction with the tube bore.

As another embodiment, the master page and the slave page are in a central symmetrical structure, the base part is positioned in the pipe hole of the master page and extends into the pipe hole of the slave page, and the rotating part is in contact connection with the pipe hole of the slave page through a needle bearing.

Further preferably, the base portion of the stationary core has a boss on an outer diameter between the parent page tube aperture and the child page tube aperture. Friction force between the master page tube hole and the slave page tube hole in the relative rotation process can be further reduced through the boss.

In summary, the utility model has the technical effects and advantages that:

according to the utility model, the master page and the sub page are connected through the shaft core, and the shaft core rotates through the needle bearing, so that the master page and the sub page keep good shaft center coaxiality on one hand, keep flexible rotation on the other hand, have no direct metal friction, and have good silencing effect.
