Notebook shaft structure: protruding shaft

The protruding rotating shaft is fixed on the host, which can make the screen fit more tightly. The biggest advantage is that when opened, the screen as a whole is upward. In this way, the screen will not block the back of the notebook, and various ports and cooling holes can be conveniently set up in the back of the notebook. From the point of view of making full use of notebook space and increasing port number, it is very advantageous. At the same time, because the protruding axis is not easy to block when rotating, the screen can be opened at a larger Angle, generally can reach 150 degrees ~ 180 degrees. But the disadvantage is that the screen thickness must be consistent with the fixed place, can not do too thin.
