1. An adjustment mechanism, comprising:
a connecting assembly, comprising two connecting components (21) arranged at an interval, wherein the two connecting components (21) have an unfolded state in which the two connecting components are away from each other and a folded state in which the two connecting components are close to each other, and at least two adjustment rod groups arranged side by side are provided between the two connecting components (21);
the at least two adjustment rod groups, each comprising a first connecting rod (22) and a second connecting rod (23) that are respectively hinged to the two connecting components (21), wherein the first connecting rod (22) and the second connecting rod (23) each comprise a connecting end (a) hinged to a corresponding connecting component (21) and a linkage end (b) away from the connecting end (a); and
a linkage rod (25), hinged to the linkage end (b) of the first connecting rod (22) and the linkage end (b) of the second connecting rod (23) in each adjustment rod group, wherein
under an action of an external force on the adjustment mechanism, the linkage rod is enabled to generate a movement tendency and hence drive the first connecting rod (22) and the second connecting rod (23) in each adjustment rod group to rotate, the two connecting components (21) are hence enabled to move away from or close to each other, and the connecting assembly is switched between the unfolded state and the folded state accordingly.
