The sliding member includes a first holding portion and a second holding portion each defining a mounting hole. The second slide rail is slidably retained in the mounting holes of the first and second holding portions. A first end of the first slide rail is fixed to a rack. A first end of the second slide rail is slidably received in a second end of the first slide rail. A second end of the second slide rail is fixed to a second end of the server module. ## Claims ### Claim 1 A sliding apparatus to be connected between a rack and a server module, the sliding apparatus comprising: a sliding member to be fixed to a first end of the server module, wherein the sliding member comprises a first side surface and a second side surface opposite to the first side surface, the sliding member comprise a first holding portion and a second holding portion each defining a mounting hole, the first holding portion and the second holding portion protrude from the first side surface, the second side surface is fixed to the server module; an elongated and sleeve shaped first slide rail slidably retained in the mounting holes of the first holding portion and the second holding portion, wherein a first end of the first slide rail is fixed to the rack; and an elongated and pole shaped second slide rail, wherein a first end of the second slide rail is slidably received in the first slide rail via a second end of the first slide rail, a second end of the second slide rail is fixed to a second end of the server module. ### Claim 2 (depends on 1) The sliding apparatus of claim 1, wherein a screw nut is screwed to the second end of the first slide rail to block the second slide rail, to prevent the second slide rail from being released from the first slide rail. ### Claim 3 (depends on 1) The sliding apparatus of claim 1, wherein a first rod protrudes on the first holding portion for engaging in the rack. ### Claim 4 (depends on 1) The sliding apparatus of claim 1, wherein a second rod protrudes on the second holding portion for engaging in the rack. ### Claim 5 A sliding apparatus to be connected between a rack and a server module, the sliding apparatus comprising: a sliding member to be fixed to a first end of the server module, wherein the sliding member comprises a first side surface and a second side surface opposite to the first side surface, the sliding member comprises a first holding portion and a second holding portion each defining two mounting holes, the first holding portion and the second holding portion protrude from the first side surface, the second side surface is fixed to the server module; two elongated and sleeve shaped first slide rails slidably retained in the mounting holes of the first holding portion and the second holding portion, wherein first ends of the first slide rails are fixed to the rack; and two elongated and pole shaped second slide rails, wherein first ends of the second slide rails are slidably received in the first slide rails via second ends of the first slide rails respectively, second ends of the second slide rails are fixed to a second end of the server module. ### Claim 6 (depends on 5) The sliding apparatus of claim 5, wherein a screw nut is screwed to the second end of each of the first slide rails to block the corresponding second slide rail, to prevent the second slide rail from being released from the first slide rail. ### Claim 7 (depends on 5) The sliding apparatus of claim 5, wherein a rod protrudes on the first holding portion for engaging in the rack. ### Claim 8 (depends on 5) The sliding apparatus of claim 5, wherein a rod protrudes on the second holding portion for engaging in the rack. ### Claim 9 An electronic device comprising: a rack; a server module comprising two side surfaces; and two sliding apparatus each arranged between a corresponding one of the two side surfaces and the rack; wherein each sliding apparatus comprises: a sliding member fixed to a first end of a corresponding one of the two side surfaces of the server module, wherein the sliding member comprises a first side surface and a second side surface opposite to the first side surface, the sliding member comprise a first holding portion and a second holding portion each defining a mounting hole, the first holding portion and the second holding portion protrude from the first side surface, the second side surface is fixed to the server module; an elongated and sleeve shaped first slide rail slidably retained in the mounting holes of the first holding portion and the second holding portion, wherein a first end of the first slide rail is fixed to the rack; and an elongated and pole shaped second slide rail, wherein a first end of the second slide rail is slidably received in the first slide rail via a second end of the first slide rail, a second end of the second slide rail is fixed to a second end of the side surface of the server module. ### Claim 10 (depends on 9) The electronic device of claim 9, wherein the rack comprises a base, two first posts extending up from a first end of the base, and two second posts extending up from a second end of the base, the first and second posts sandwich the server module, the first and second posts each define a plurality of mounting holes, the first end of the first slide rail is fixed to one of the first mounting holes of the corresponding first post, the second end of the second slide rail extends through one of the mounting holes of the corresponding second post to be fixed to the server module. ### Claim 11 (depends on 10) The electronic device of claim 10, wherein a first rod protrudes on the first holding portion for engaging in one of the mounting holes of the second post, a second rod protrudes on the second holding portion for engaging in one of the mounting holes of the first post. ### Claim 12 (depends on 9) The electronic device of claim 9, wherein a screw nut is screwed to the second end of the first slide rail to block the second slide rail, to prevent the second slide rail from being released from the first slide rail. ### Claim 13 (depends on 9) The electronic device of claim 9, wherein a mounting piece is fixed to the second end of the side surface of the server module, the mounting piece defines a mounting slot, the second end of the second slide rail is detachably engaged in the mounting slot. ### Claim 14 (depends on 13) The electronic device of claim 13, wherein a thumbscrew is movably attached to the mounting piece for screwing in the rack. ### Claim 15 (depends on 9) The electronic device of claim 9, further comprising a locking apparatus attached to the first end of the server module, wherein the locking apparatus is detachably attached to the sliding member. ### Claim 16 (depends on 15) The electronic device of claim 15, wherein the locking apparatus comprises a fixing member fixed to the server module, a releasing member pivotably attached to the fixing member, and a resilient member arranged between the releasing member and the fixing member. ### Claim 17 (depends on 16) The electronic device of claim 16, wherein a pin protrudes on the sliding member, a locking slot is defined in the fixing member, the pin pushes the releasing member to slide in the locking slot, the releasing member is biased by the resilient member to lock the pin in the locking slot.
