Abstract

The utility model is a screen cap rotating shaft structure mainly comprising a shaft base, a connection unit and a torsion device. The screen rotating shaft structure with easy assembly and small volume reduces the number of components. The direct arrangement of embedded slot on the side board of the shaft base and the butt with the torsion device decrease components and reduce the volume of whole assembly. In particular, less space can be occupied when the rotating shaft of the device is assembled on a notebook computer. Besides, when assembly is finished, the rotating shaft end riveted on the packing component can keep friction coefficient constant without variable torsion value caused by constant cover-lifting.
