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.

1. A sliding mechanism, comprising: an outer rail;an inner rail;a middle rail between the outer rail and the inner rail, the middle rail having a resisting portion protruding therefrom, the middle rail slidably mounted to the outer rail in a first direction and the inner rail slidably mounted to the middle rail in the first direction;a latching assembly including a first protrusion positioned at the inner rail, a second protrusion positioned at the inner rail and spaced apart from the first protrusion, a third protrusion positioned at the outer rail, a first roller and a second roller being slidably mounted on the middle rail in a second direction perpendicular to the first direction, a latching slot defined in the outer rail communicating with the third protrusion and a stopping surface defined in the latching slot opposite to the third protrusion;wherein the middle rail defines a first guiding groove to guide the first roller to slide relative to the middle rail in the second direction and a second guiding groove to guide the second roller to slide relative to the middle in the second direction;when the inner rail slides relative to the middle rail in the first direction, the second roller slides along the second protrusion until the first protrusion slides to and latches the first roller to make the middle rail sliding with the inner rail; and then the second roller slides along the third protrusion and the second guiding groove, the first roller slides to and along the third protrusion so the first roller slides along the first guiding groove relative to the middle rail in the second direction to release the first roller from the first protrusion and the second roller slides in the latching slot from the third protrusion in the first direction until the resisting portion resists the stopping surface to prevent the middle rail from sliding relative to the outer rail such that the first roller slides along the first protrusion to make the inner rail further extends relative to the middle rail. 2. The sliding mechanism as claimed in claim 1, wherein the inner rail includes two sliding plates respectively located at opposite sides thereof; the middle rail includes two sliding blocks respectively positioned at opposite sides thereof, each sliding block defines a sliding groove which slidably engages one of the sliding plates to enable the middle rail to slide relative to the inner rail. 3. The sliding mechanism as claimed in claim 2, wherein the outer rail has two sliding slots respectively defined at opposite sides thereof, each sliding slot slidably engages with one of the sliding blocks so the outer rail can slide relative to the middle rail. 4. The sliding mechanism as claimed in claim 1, wherein the first protrusion and the second protrusion are both positioned at one side of the inner rail facing the middle rail, and the first protrusion is spaced apart from the second protrusion. 5. The sliding mechanism as claimed in claim 4, wherein the first protrusion includes a first protrusion valley and a first protrusion peak; the second protrusion includes a second protrusion valley and a second protrusion peak; the third protrusion includes a third protrusion valley and a third protrusion peak. 6. The sliding mechanism as claimed in claim 5, wherein the first roller includes a main body, a first pin protruding from one side of the main body, a second pin protruding from another side of the main body; the first pin slides along the first protrusion when the middle rail slides relative to the inner rail, and the second pin slides along the third protrusion when the middle rail slides relative to the outer rail. 7. The sliding mechanism as claimed in claim 6, wherein the first roller further defines a securing slot around the second pin near the main body, the securing slot slidably secures with the portions of the middle rail surrounding the first guiding groove so the first roller is slidably secured to the middle rail. 8. The sliding mechanism as claimed in claim 7, wherein the first roller further defines a retaining slot defined around the first pin near the main body; the sliding mechanism further includes a first elastic element including a first retaining ring formed one end thereof and wrapping in the retaining slot to latch the first roller to the first elastic element. 9. The sliding mechanism as claimed in claim 8, wherein the first elastic element further includes a first latching portion formed at the center thereof; the middle rail further includes a first hook latching the first latching portion to hold the first elastic element to the middle rail. 10. The sliding mechanism as claimed in claim 9, wherein the middle rail further includes a first opening; the first elastic element further includes a first inserting portion formed another end thereof which is inserted in the first opening to assist the first elastic element to hold on the middle rail. 11. The sliding mechanism as claimed in claim 10, wherein the second roller includes a main board, a first post protruding from one side of the main board, a second post protruding from another side of the main board; the first post slides along the second protrusion when the middle rail slides relative to the inner rail, and the second post slides along the third protrusion when the middle rail slides relative to the outer rail. 12. The sliding mechanism as claimed in claim 11, wherein the second roller further defines a securing groove around the second post near the main board, the securing groove slidably secures with the portions of the middle rail surrounding the second guiding groove so the second roller is slidably secured to the middle rail. 13. The sliding mechanism as claimed in claim 12, wherein the second roller further defines a retaining groove defined around the first post near the main board; the sliding mechanism further includes a second elastic element including a first retaining ring formed one end thereof and wrapping in the retaining groove to latch the second roller to the second elastic element. 14. The sliding mechanism as claimed in claim 13, wherein the second elastic element further includes a second latching portion formed at the center thereof; the middle rail further includes a second hook latching the second latching portion to hold the second elastic element to the middle rail. 15. The sliding mechanism as claimed in claim 14, wherein the middle rail further includes a second opening; the second elastic element further includes a second inserting portion formed another end thereof which is inserted in the second opening to assist the second elastic element to hold on the middle rail. 16. The sliding mechanism as claimed in claim 5, wherein the latching slot communicates with the third protrusion peak, and the stopping surface is defined opposite to the third protrusion peak and a resisting surface is defined in the latching slot near the third protrusion peak.
