At the same time, the pushing members 53 are also pushed by the elastic force of the pushing elastic member 54 to push the pushing blocks 24 to drive the sliding plates 22 to move away from the linkage brackets 51, so that the The flexible screen 21 provides an outward pulling force, so that the flexible screen 21 can be flattened more quickly. Referring to FIGS. 2 and 18 to 20, when transitioning from the unfolded position to the outer folded position, the first outer support tubes 412 of the outer support units 41 pivot downward relative to the central outer support tube 411 and The second outer support tubes 413 respectively pivot downward relative to the first outer support tubes 412, and the first middle support tubes 422 of the middle support units 42 pivot downward relative to the central middle support tube 421 And the second middle support tubes 423 respectively pivot downward relative to the first middle support tubes 422, and the first inner support tubes 432 of the inner support unit 43 are downward relative to the central inner support tube 431 And the second inner support tubes 433 respectively pivot downward relative to the first inner support tubes 432, and the torsion plate units 44 are closely stacked on each other when rotating, the torsion force generated can stably maintain the mechanism The shell 11 is located in the outer folding position. At this time, the surfaces of the outer support units 41, the middle support units 42 and the support tubes of the inner support unit 43 together form a semicircular arc-shaped support surface to support the screen unit 2. Because the screen unit 2 is movable relative to the casings 11, the flexible screen 21 can be closely attached to the above-mentioned supporting surface without being squeezed and deformed to cause damage. Refer to Figure 2 and Figure 13 to Figure 15. Similarly, when the foldable screen device 100 is used up, the user can fold the casings 11 so that the casings 11 can be converted to the inner folding position. When the unfolded position is converted to the inner folded position, the first outer support tubes 412 of the outer support units 41 pivot upward relative to the central outer support tube 411, and the second outer support tubes 413 respectively relative to the The first outer support tubes 412 pivot upward, the first middle support tubes 422 of the middle support units 42 pivot upward relative to the central middle support tube 421, and the second middle support tubes 423 are respectively relative to the The first middle support tube 422 pivots upward, the first inner support tubes 432 of the inner support unit 43 pivot upward relative to the central inner support tube 431, and the second inner support tubes 433 respectively relative to the first inner support tubes 431. An inner support tube 432 pivots upward, and the torsion force generated when the torsion plate units 44 are closely stacked on each other can also stably maintain the casings 11 in the inner folded position. At this time, the screen unit 2 is accommodated The aforementioned water-drop-shaped space will not bend the screen unit 2 excessively and cause damage.

In summary, the new foldable screen device 100 of the present invention can be movably accommodated in the track grooves 141 of the screen rails 14 by the slide plates 22 of the screen unit 2, and the casings 11 are in the casings. When the unfolded position 11 in the unfolded state and the outer folded position where the base walls 111 of the casings 11 face each other are changed, the screen unit 2 can move relative to the casings 11 to prevent the screen unit 2 from being affected by the machine. The difference between the inner and outer diameters of the shell 11 is caused by pulling and squeezing and then being damaged. Therefore, it can indeed achieve the purpose of cost innovation.
