When the screen faces the base, it can be operated as a notebook computer. On the contrary, when the screen is turned and back to the base while covering the base, it can be operated with a stylus at this time. Operate to form a tablet computer.

Traditionally, in order for the screen to rotate relative to the base, a rotating mechanism must be designed between the screen and the base, which connects the screen and the base and rotates the screen relative to the base.

However, the traditional rotating mechanism is simply a circular structure and assembled between the screen and the base. Such a design will cause the circular rotating mechanism to protrude out of the base and occupy space.

In addition to the dagger, the traditional rotating mechanism is equipped with a money chain element, which is fixed on the screen to turn the screen relative to the base (turn the screen down to cover the base, or make The screen flips upwards), however, the traditional chain element is fixed on the rotating mechanism and rotates with the rotating mechanism, and its position will change with the rotation of the rotating mechanism, causing the screen to follow the rotation and cannot completely cover the top of the base. Offset means that there will be an unnecessary space beside the screen. In addition, the traditional money chain components have poor stability and are prone to shaking, which is not very ideal.
