As positioning slide 631 slides, a force is applied to ball 650 causing ball spring 653 to compress and ball 650 slides out of ball hole 630 and retracts fully into ball slide channel 652 without affecting the sliding motion of positioning slide 631.

When the electronic device is in the folded state, the first surface faces the third surface, and the connecting holder 4 is located outside the screen panel holder main groove. The bent portion 30 formed by the flexible display 3 is positioned in the first and second bracket grooves 10 and 20 and the space therebetween. At this time, half of the interlocking slide plate 531 is located in the interlocking guide main groove 52, and the other half is located in the screen panel bracket main groove; similarly, one half of the positioning slide 631 is positioned in the positioning guide main groove 62, and the other half is positioned in the panel bracket main groove. The ball 650 is no longer subjected to external force, the ball spring 653 returns to return the ball 650, and the portion of the ball 650 outside the ball slide channel 652 falls below the slide channel, thereby providing a closed position feeling.

The process of the electronic device from the folded state to the flat state is opposite to the process from the flat state to the folded state, and is not described in detail herein.

According to the invention, through the arrangement of the linkage guide main groove 52/the positioning guide main groove 62 and the linkage sliding plate 531/the positioning sliding plate 631, the first screen panel 1 is overturned around the central line of the linkage guide main groove 52/the positioning guide main groove 62 corresponding to the first screen panel, and the second screen panel 2 is overturned around the central line of the linkage guide main groove 52/the positioning guide main groove 62 corresponding to the second screen panel, so that a sufficient space is left between the first screen panel 1 and the second screen panel 2 to accommodate the bent part 30 of the flexible screen in a closed state of the electronic equipment. Further, the first screen board 1 and the second screen board 2 are synchronously rotated and stably rotated by the arrangement of the linkage unit 5, and the electronic equipment has positioning feeling and is flatly and stably folded by the arrangement of the positioning unit 6.

The above-mentioned embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
