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.

The invention claimed is: 1. An articulation, comprising: a first shell having an inner wall provided with a plurality of first teeth; a second shell rotatable relative to the first shell and having an inner wall provided with a plurality of second teeth; a gear wheel movably mounted between the fi
The invention claimed is: 1. An articulation, comprising: a first shell having an inner wall provided with a plurality of first teeth; a second shell rotatable relative to the first shell and having an inner wall provided with a plurality of second teeth; a gear wheel movably mounted between the first shell and the second shell and intermeshing with the first teeth of the first shell and the second teeth of the second shell to lock the second shell onto the first shell; a push button movably mounted on the second shell and rested on the gear wheel to push and move the gear wheel to detach from the second teeth of the second shell so as to unlock the second shell from the first shell so that the second shell is rotatable relative to the first shell; and an elastic member biased between the first shell and the gear wheel to push the gear wheel toward the second shell and the push button; wherein the second shell has an inner portion formed with at least one limit slot, and the gear wheel has a first side directed toward the second shell and formed with at least one limit plate, the at least one limit plate extending into the respective limit slot of the second shell when the second shell is locked onto the first shell, and the at least one limit plate separated from the respective limit slot when the second shell is unlocked from the first shell. 2. The articulation in accordance with claim 1, wherein the first shell has a peripheral wall formed with a first receiving groove, and the second shell has a peripheral wall formed with a second receiving groove aligning with the first receiving groove of the first shell. 3. The articulation in accordance with claim 1, wherein the gear wheel has a toothed periphery extending through a whole circumferential length of the gear wheel and intermeshing with the first teeth of the first shell and the second teeth of the second shell. 4. The articulation in accordance with claim 3, wherein the toothed periphery of the gear wheel has an upwardly inclined guide ramp rested on the inner wall of the first shell and the inner wall of the second shell so that the gear wheel is pushed by the elastic member to move toward the second teeth of the second shell by guidance of the guide ramp. 5. The articulation in accordance with claim 1, wherein the at least one limit plate comprises a plurality of limit plates. 6. The articulation in accordance with claim 1, wherein the at least one limit slot comprises a plurality of limit slots. 7. The articulation in accordance with claim 1, wherein the gear wheel has a second side directed toward the first shell and rested on the elastic member. 8. The articulation in accordance with claim 1, further comprising a screw member in turn extended through the first shell, the elastic member, the gear wheel and the second shell, and a nut screwed onto the screw member and rested on the second shell, so that the first shell is combined with the second shell, and the gear wheel is movable on the screw member relative to the first shell and the second shell. 9. The articulation in accordance with claim 8, wherein the screw member has a first end formed with an enlarged head secured in the first shell and a second end protruded from the second shell and screwed into the nut. 10. The articulation in accordance with claim 1, wherein the push button has two downwardly extending radially opposite push plates each extended through the second shell and each rested on the gear wheel to push the gear wheel. 11. The articulation in accordance with claim 10, wherein each of the push plates of the push button has a distal end formed with an outwardly extending locking hook hooked onto a bottom wall of the second shell to attach the push button to the second shell. 12. The articulation in accordance with claim 1, wherein the second shell is rotatable relative to the first shell between a first position where the at least one limit plate of the gear wheel extends into the respective limit slot of the second shell, so that the gear wheel is pushed by the elastic member to move toward the second teeth of the second shell to lock the second shell onto the first shell and to push the push button to partially protrude outwardly from the second shell, and a second position where the at least one limit plate of the gear wheel is separated from the respective limit slot of the second shell, so that the gear wheel is stopped by a bottom wall of the second shell and is not pushed by the elastic member, and that the second shell is rotatable freely relative to the first shell through a relatively larger angle without having to press the push button successively. 13. The articulation in accordance with claim 1, wherein the gear wheel is located between the first shell and the second shell by push of the elastic member so that the gear wheel intermeshes with the first teeth of the first shell and the second teeth of the second shell at a normal state, and the at least one limit plate of the gear wheel extends into the respective limit slot of the second shell at a normal state. 14. The articulation in accordance with claim 1, wherein when the gear wheel is pushed by the push button to detach from the second teeth of the second shell, each of the limit plates of the gear wheel is separated from the respective limit slot of the second shell. 15. The articulation in accordance with claim 1, wherein the first teeth of the first shell are arranged in an annular shape, and the second teeth of the second shell are arranged in an annular shape.
