A leverage-release type silent wrench structure comprised of a ratchet wheel and a torsion handle having a hinge section at one end that is situated next to the ratchet wheel. A clutch block curves upward from one side of the hinge section and a toothed surface consisting of a plurality of teeth is disposed along the arc-shaped inner side of the clutch block that provides for enmeshment with the ratchet wheel. A mounting base and a protective cover in an aligned arrangement accommodate the positioning of the ratchet wheel and the hinge section of the torsion handle within them. A linkage component pivotably conjoins the mounting base, the protective cover, and the hinge section of the torsion handle and, furthermore, such that the linkage component serves as the center point of rotation of the torsion handle. Pulling the torsion handle causes its clutch block to move against the ratchet wheel such that the toothed surface enmeshes the ratchet wheel, enabling the torsion handle to initiate the rotation of the ratchet wheel and thereby rotate a work object. Pulling the torsion handle in the opposite direction causes the separation of the toothed surface of the clutch block from the ratchet wheel, enabling the torsion handle to be rotated back to its initial starting position in a disengaged state around the linkage component at the center point.
