description The utility model discloses a torsion ratchet handle which comprises a shell and a handle installed on the shell and further comprises a fixed ratchet, a movable ratchet, a rotating shaft, a rebound mechanism and a torsion adjusting mechanism, the rotating shaft is rotatably assembled in the shell, and the fixed ratchet is rotatably assembled in the shell and fixedly connected with the rotating shaft; the movable ratchet wheel is limited in the shell in the circumferential direction and arranged opposite to the fixed ratchet wheel, the springback mechanism is arranged between the movable ratchet wheel and the torsion adjusting mechanism so as to apply elastic force towards the fixed ratchet wheel to the movable ratchet wheel, the torsion adjusting mechanism adjusts the initial deformation quantity of the springback mechanism, and the initial deformation quantity of the springback mechanism is adjusted by the torsion adjusting mechanism. Therefore, interaction force between the movable ratchet wheel and the fi
