a first extending module, adapted to be connected to a stand of the electronic device, comprising two half-members disposed in the inner space, each of the half-members has a curved portion at one end thereof; a torque-stroke controlling mechanism having one end pivotally connected between the half-members and the other end at which a first shaft is disposed, and the shaft pivotally and slidably extends through the stroke grooves of the two half-housings; a second extending module comprising two half sliding members slidably disposed on respective outer sides of the first extending module, each of the half sliding member having a push portion disposed on one end thereof and facing a bottom of the first extending module, a stop portion disposed behind the push portion, and a guiding tab having a curved shape and a predetermined length disposed on the other end thereof and slidably engaging the respective curved groove; a sliding device disposed between the first extending module and the second extending module; an elastic member having one end disposed between the half-housings and the other end biasing the second extending module; and a stop sheet disposed between the half-housings and having one end facing a bottom of the second extending module for limiting the relative movement between the second extending module and the housing. ### Claim 2 (depends on 1) The hinge device as claimed in claim 1, wherein the torque-stroke controlling mechanism comprises a torque module connected to a connecting member in which the first shaft is disposed. ### Claim 3 (depends on 2) The hinge device as claimed in claim 2, wherein the torque module has a sleeve through which a second shaft extends, and the first extending module comprises two grooves with which two ends of the second shaft engages. ### Claim 4 (depends on 1) The hinge device as claimed in claim 1, wherein the sliding device comprises two first rails disposed on an outer side of the half-members, and each of the half sliding members has a curved groove in which the first rail slides. ### Claim 5 (depends on 1) The hinge device as claimed in claim 1, wherein the elastic member is a coiled spring, and the one end has two sides and the other end is U-shaped, each of the half housings has a chamber accommodating the elastic member, and the chamber has two slots into which the two sides of the one end are inserted, and a bolt extends through the elastic member. ### Claim 6 (depends on 1) The hinge device as claimed in claim 1, wherein the second extending module has a pressing portion configured to be pressed by the other end of the elastic member. ### Claim 7 (depends on 5) The hinge device as claimed in claim 5, wherein the second extending module has a pressing portion configured to be pressed by the other end of the elastic member which is U-shaped. ### Claim 8 (depends on 1) The hinge device as claimed in claim 1, wherein the stop sheet has a convex portion, and the second extending module has a stopping end on which a recess configured to engage the convex portion is formed. ### Claim 9 (depends on 8) The hinge device as claimed in claim 8, wherein the stop sheet is positioned on a depressed portion of the two half-housings, and the convex portion faces the stop portion and the recess.
