Like this, can satisfy the flexible screen body and hold the demand after folding, can reduce the emergence to the phenomenon such as excessive extrusion of the flexible screen body when folding.

In an optional implementation manner, when the first structural member and the second structural member move back to the unfolded state, the sliding end of the first main swing link slides towards one end of the first structural member, which is close to the main shaft, the pushing end of the first main swing link pulls the first connecting rod, the first connecting rod pushes the second connecting rod to rotate relative to the second main swing link, and drives the second sliding cover to move to a third position;

the first sliding cover plate and the second sliding cover plate are positioned on the same plane, and the flexible screen body is laid on the first sliding cover plate, the second sliding cover plate and the main shaft.

Because the sliding end of the first main swing rod slides towards the end, close to the main shaft, of the first structural member, the end, far away from the flexible screen body, of the first structural member also moves close to the main shaft while the first structural member rotates relative to the main shaft, and similarly, the end, far away from the flexible screen body, of the second structural member also moves close to the main shaft while the second structural member rotates relative to the main shaft, so that the length, far away from the flexible screen body, of the first structural member and the second structural member (the length of a fitting line formed by connecting lines of the end, far away from the main shaft, of the first structural member and the end, far away from the main shaft, of the second structural member) is adjusted, and therefore, the length, close to the flexible screen body, of the first structural member and the second structural member (the length of the fitting line formed by connecting lines of the end, far away from the main shaft, of the first structural member and the end, far away from the main shaft, of the second structural member, of the flexible screen body) is basically unchanged in a folded state and an unfolded state, therefore, the length of the flexible screen body in the folded state is equal to that of the flexible screen body in the unfolded state, and the flexible screen body is effectively prevented from being pulled in the unfolding process.

In an optional implementation manner, when the first structural member and the second structural member are moved away from each other to the unfolded state, one end of the first structural member, which is far away from the main shaft, and one end of the second structural member, which is near to the main shaft, are abutted to shield one surface of the main shaft, which is far away from the flexible screen body.
