After the transmission column/worm is installed in the electronic device, because the structural strength of the transmission worm clamped by the fixing sheet and the pressing sheet is poor, when the display unit and the keyboard input unit relatively rotate to generate larger acting force on the three worms, the fixing sheet and the pressing sheet can be expanded to shift the transmission worm or enable the two worms to axially slide, so that the stability of the motion of the transmission worm and the synchronous motion between the transmission worm and the other worms can not be improved, and the screen shaking is easily caused when a user touches the screen. Moreover, when the elastic component is matched with the friction washer or a plurality of butterfly-shaped elastic sheets are used for providing torsion, the whole structure is complex.
In addition, when the structure is installed in an electronic device with a single flexible screen, the two half parts of the flexible screen are turned over and closed relatively, so that the bent part of the flexible screen after being folded inwards is in a drop shape, the flexible screen is easy to damage due to the connection relation and action of the component members and the component members, and the service life is easy to be influenced.
