Specifically, the first sub through hole may be disposed corresponding to the second sub member, and the second sub through hole may be disposed corresponding to the first sub member.

Specifically, as shown in fig. 4, the height of the extendable member 44 at the first position is lower than the height at the second position, and the heights at the first, third, and fourth positions are the same. When the telescopic member 44 is located at the first position, the second frame body 3 moves to the left to the limit position, the flexible screen 7 is completely contracted, the main body structure 42 can be located at the first position, the first elastic member 43 is in the extended state, the ratchet 48 can be meshed with the ratchet bar 49, and the self-locking mechanism 4 is in the locked state.

Further, the driving mechanism 1 drives the second frame body 3 to move rightward, and the extensible member 44 can slide into the first sliding track 5111 from the position (r); in the process that the telescopic piece 44 slides to the second position in the first sliding track 5111, the flexible screen 7 is gradually unfolded; when the telescopic member 44 slides out of the first sliding track 5111 to the third position, the flexible screen 7 is completely unfolded, and the second elastic member 45 can spring open the telescopic pin 441.

When the telescopic member 44 slides to the position d, if the second frame 3 continues to move rightward, the telescopic member 44 can continue to slide to the next sub limiting plate 521; if the second frame 3 moves to the left, the telescopic element 44 can slide from the position d to the position e, and then slide to the second sliding track 5112, the second frame 3 continues to move to the left, the telescopic element 44 can slide to the position f, and under the action of the first elastic element 43, the limiting structure 421 can drive the main body structure 42 to switch from the second position to the first position, so that the telescopic element 44 returns to the position a from the position f.
