an outer retaining wall, spaced apart from the magnetic strip unit and located between the two lateral retaining walls, the outer retaining wall being connected with the two lateral retaining walls, so that the magnetic strip unit, the two lateral retaining walls and the outer retaining wall jointly forming a hollow region.

3. The foldable flexible screen terminal according to claim 2 , wherein the hollow regions of the plurality of flexible member units collectively form a receiving space of the rollable flexible member.

4. The foldable flexible screen terminal according to claim 3 , wherein a micropore structure is arranged on a bellows surface of the bellows structure, the micropore structure is configured to allow air to enter and exit the receiving space and to block liquid from entering the receiving space.

5. The foldable flexible screen terminal according to claim 3 , wherein an air vent is provided in the foldable flexible screen terminal, and the air vent is configured to ventilate the receiving space with an external environment.

6. The foldable flexible screen terminal according to claim 2 , wherein the flexible member unit further comprises at least one support pillar, and the at least one support pillar is located between the magnetic strip unit and the outer retaining wall.

7. The foldable flexible screen terminal according to claim 1 , wherein a cross section of the magnetic strip unit has a symmetrical irregular shape.

8. The foldable flexible screen terminal according to claim 7 , wherein the magnetic strip unit comprises a top surface, a bottom surface, and two side surfaces between the top surface and the bottom surface, each of the side surfaces comprises a first contact surface at an obtuse angle to the top surface and a second contact surface at a right angle to the top surface.

9. The foldable flexible screen terminal according to claim 8 , wherein each of the side surfaces further comprises a third contact surface between the first contact surface and the second contact surface, and the third contact surface is connected with the first contact surface and the second contact surface.

10. The foldable flexible screen terminal according to claim 9 , wherein the third contact surface is at an acute angle to the top surface.

11. The foldable flexible screen terminal according to claim 1 , wherein the magnetic strip units of the plurality of flexible member units are located at the same side of the rollable flexible member.

12. The foldable flexible screen terminal according to claim 1 , wherein the plurality of bellows structures comprise a second bellows structure, each of adjacent screen terminal portions is connected to the flexible member unit adjacent to the one of adjacent screen terminal portions via the second bellows structure.
