1. A hinge torque fixing structure, comprising: a hinge having a first end provided with a connecting portion on which several key holes are disposed, and a second end provided with a hinge hole defined by an uninterrupted cylindrical wall; a fulcrum having a first end provided with a connecting portion on which several key holes are disposed and a second end provided with a hinge shaft to be inserted into the hinge hole; and a ring-shaped polygonal torque shrapnel having an interior surface and exterior surface is provided between the hinge hole of the hinge and the hinge shaft of the fulcrum, wherein the torque shrapnel has a plurality of corners, the shrapnel having a thickness extending between the interior and exterior surface that is slightly greater than a thickness of a gap extending between the hinge shaft and the hinge hole, such that after the hinge shaft is rotated by pressing the torque shrapnel to the hinge shaft due to elastic deflection in the torque shrapnel, the hinge shaft shall be fixed after it is rotated to any position.
