ABSTRACT:
An articulation includes a first shell, a second shell, a gear wheel, a push button, and an elastic member. Thus, the second shell is unlocked from the first shell by pressing the push button so that the second shell is rotatable freely relative to the first shell so as to adjust the angle between the second shell and the first shell. In addition, when each of the limit plates of the gear wheel is separated from a respective limit slot of the second shell, the gear wheel is stopped by the second shell and is not pushed by the elastic member, so that the second shell is rotatable freely relative to the first shell through a larger angle without having to press the push button successively, thereby facilitating a user adjusting the angle in an energy-saving manner.
