A pivot structure is used to pivotally connect a first object to a second object includes a pivot hole and a pivot portion. The pivot hole is disposed at the second object, while the pivot portion is disposed at the first object. The pivot portion has a discontinuous ring with an outside diameter lager than an aperture of the pivot hole. The discontinuous ring can be squeezed to be deformed and be inserted into the pivot hole, such that the discontinuous ring tightly bears against the pivot hole to maintain an included angle between the first object and the second object at any time, thereby a user can steplessly adjust the included angle of the two objects.
