A sliding mechanism includes an outer rail, an inner rail, a middle rail and a latching assembly. The middle rail has a resisting portion and is slidably mounted to the outer rail and the inner rail is slidably mounted to the middle rail. The latching assembly includes a first protrusion, a second protrusion, a third protrusion, a first roller and a second roller, a latching slot and a stopping surface. When the inner rail slides relative to the middle rail, the first protrusion resists the first roller so the middle rail sliding with the inner rail; and then the first roller slides along the third protrusion to release the first roller from the first protrusion. The second roller then slides in the latching slot until the resisting portion resists the stopping surface; and then the first roller slides along the first protrusion so the inner rail further extends relative to the middle rail. |
