1. A rotating mechanism, comprising:
a shaft cover; and
at least one folding assembly, wherein the folding assembly comprises:
a connection plate, wherein a surface of the connection plate away from the shaft cover is a lamination surface, the lamination surface is used for lamination to a part of a foldable screen, the connection plate can be stretched and deformed in a first direction, the first direction is parallel to the lamination surface, and the connection plate has, in the first direction, a first side and a second side that opposite to each other;
a first swing arm, disposed on the first side of the connection plate, and separately rotatably connected to the connection plate and the shaft cover;
a second swing arm, disposed on the second side of the connection plate, and separately rotatably connected to the connection plate and the shaft cover; and
a transmission assembly, in a transmission connection to the first swing arm and the second swing arm, and configured to drive the first swing arm and the second swing arm to rotate in reverse directions, so that the first swing arm and the second swing arm rotate between a folded position and an unfolded position; and
in a process in which the first swing arm and the second swing arm rotate from the folded position to the unfolded position, the connection plate is stretched and deformed, and moves in a direction away from the shaft cover; and in a process in which the first swing arm and the second swing arm rotate from the unfolded position to the folded position, the connection plate is stretched and deformed, and moves in a direction close to the shaft cover,
wherein the connection plate comprises a first sub-plate and a second sub-plate, at least a part of the first sub-plate is plug-connected to at least a part of the second sub-plate, and the first sub-plate is slidably connected to the second sub-plate; and
one end that is of the first sub-plate and that is away from the second sub-plate is rotatably connected to the first swing arm, and one end that is of the second sub-plate and that is away from the first sub-plate is rotatably connected to the second swing arm,
wherein the first sub-plate comprises a first plate body and a first comb structure, and the first comb structure is located on one side that is of the first plate body and that is close to the second sub-plate, and is connected to the first plate body:
the second sub-plate comprises a second plate body and a second comb structure, and the second comb structure is located on one side that is of the second plate body and that is close to the first sub-plate, and is connected to the second plate body; and
the first comb structure and the second comb structure are plug-connected to each other, and
wherein the first comb structure comprises a plurality of first bumps, and there is a first gap between two adjacent first bumps;
the second comb structure comprises a plurality of second bumps, and there is a second gap between two adjacent second bumps; and
each of the plurality of first bumps is inserted into a corresponding second gap, and each of the plurality of second bumps is inserted into a corresponding first gap.
