Claim 0:
1. A folding hook structure for arranging a first object and a second object being relatively rotatable in respect to each other to an extended state or a collapsed state, the folding hook structure comprising:
a shell, fixed to the first object, and at least partially accommodates other parts of the folding hook structure;
a rotating disk, fixed to the second object, and disposed in the shell to be rotatable around a rotation center in respect to the shell, with a folding hook groove disposed on a disk surface of the rotating disk, the folding hook groove including a circumferential section extending in a circumferential direction of the rotating disk with the rotation center as a center, and a radial section extending from the circumferential section along a radial direction of the rotating disk;
a folding hook, disposed in the shell, and arranged movable between a locked position and a released position along the radial direction of the rotating disk, the folding hook being inserted in the folding hook groove;
wherein in the locked position, the folding hook is engaged in the radial section of the folding hook groove to prevent a relative rotation between the shell and the rotating disk; and in the released position, the folding hook is slidable along the circumferential section of the folding hook groove to allow the relative rotation between the shell and the rotating disk;
wherein when the folding hook is in the locked position, the first object and the second object are in the collapsed state; and when the folding hook is in the released position, the first object and the second object are in the extended state.
