1. A flexible supporting structure, comprising:
a linkage mechanism configured to be bent for adjustment, the linkage mechanism having two rows of linkage plate assemblies positioned adjacent to each other and each comprising linkage toothed plates;
wherein a first row of the two rows includes at least two linkage toothed plates that are meshed and connected in sequence;
wherein at least one end portion of each of the at least two linkage toothed plates is provided with a meshing tooth portion such that a first meshing portion of a first linkage toothed plate meshes with a second meshing portion of a second linkage toothed plate, the first meshing portion opposing the second meshing portion;
wherein the linkage mechanism is configured such that an end of a linkage toothed plate of the first row of the two rows is spaced apart from an end of a linkage toothed plate of a second row of the two rows;
wherein a pivot shaft connects two adjacent linkage toothed plates of the two rows and is configured such that the linkage toothed plates are capable of being rotated synchronously with the pivot shaft;
wherein the pivot shaft is locked with the two adjacent linkage toothed plates through a lock nut; and
wherein an elastic member is sleeved on the pivot shaft, and the elastic member is located between the lock nut and one of the two adjacent linkage toothed plates.
