An adjustable torque hinge includes a set hinge, a torque providing unit and a torque adjusting unit. The set hinge unit couples a first and second wing plate with a pivot pin. The first and second wing plates forms a pin joint with a first sleeve and second sleeve. The torque providing unit includes a torque spring to provide turn back recovery. A torque adjusting unit has a torque adjustment member. The first sleeve includes a first cam, and the torque adjustment member includes a second cam which couples with the first cam to drive the torque adjustment member to the torque spring. Conversion between the first and second sleeves enables the bearing hinge to be used in both directions, accumulating force both in normal and reverse directions to adjust the torque force for opening and closing operations.

1. An adjustable torque hinge comprising: a hinge unit having a first wing plate, a second wing plate, a first sleeve and a second sleeve, said first wing plate including first sleeve knuckles, said second wing plate including second sleeve knuckles, said first and second sleeve knuckles being coupl
1. An adjustable torque hinge comprising: a hinge unit having a first wing plate, a second wing plate, a first sleeve and a second sleeve, said first wing plate including first sleeve knuckles, said second wing plate including second sleeve knuckles, said first and second sleeve knuckles being coupled together, said first sleeve being sleeved in said first and second sleeve knuckles, an outer periphery of the first sleeve connected co-movably to said second sleeve knuckles, said first sleeve provided with a first cam therein, wherein said outer periphery of said first sleeve includes an engaging surface fitted in said second sleeve knuckles, and wherein said hinge unit further includes a stop pin extending through one of said second sleeve knuckles to fix said first sleeve relative to said second sleeve knuckles;a torque providing unit having a movable pivot extending through said first and second sleeve knuckles, and a torque spring sleeved on said pivot, an outer periphery of said pivot being connected co-movably to said first sleeve knuckles of said first wing plate, said torque spring having a first end working on said pivot; anda torque adjusting unit having a movable torque adjustment member set within said first sleeve, and a spring disposed on said torque adjustment member, said torque adjustment member having an outer periphery that is provided with a second cam, said spring biasing resiliently said torque adjustment member to couple said second cam to said first cam, an outer end of said torque adjustment member being formed with an adjustment hole for a driving operation of a tool, said torque spring further having a second end that works on said torque adjustment member such that when said torque adjustment member rotates in a direction, said first cam and said second cam are coupled to each other to be co-rotatable and when said torque adjustment member rotates in another direction, said first cam and second cam are uncoupled to rotate in an opposite direction resulting in idle rotation. 2. The adjustable torque hinge according to claim 1, wherein said outer periphery of said pivot includes a protrusion mounted inside one of said first sleeve knuckles, and wherein said protrusion has a slot for insertion of said first end of said torque spring. 3. The adjustable torque hinge according to claim 1, further comprising a speed adjusting unit including a speed adjustment member that is threadedly disposed within said second sleeve, a resilient member that is disposed in said second sleeve and that is able to be pressed by said speed adjustment member, and a cam member that is disposed movably in said second sleeve and that is able to be pressed by said resilient member. 4. The adjustable torque hinge according to claim 3, wherein said pivot includes a cam portion, said cam member being biased by said resilient member to contact said cam member so as to generate a resisting force. 5. The adjustable torque hinge according to claim 4, wherein said cam member is formed with a locating slot for insertion of said cam portion at a predetermined angular position.
