  • Torque regulating assembly
    Patent number: 7281459
    Abstract: A torque regulating assembly includes a first tubular shell having at least one groove disposed along the longitudinal axis of the first tubular shell and a second tubular shell having at least one aperture, wherein the first tubular shell is screwed into the second tubular shell with threads, making the aperture corresponding to the groove. A torque regulating ring having at least one screw hole is put around the second tubular shell. A screwing element is screwed into the screw hole, and the front tip of the screwing element passes through the aperture and moves toward the groove, so that a position of the second tubular shell relative to the first tubular shell is fixed. Then a maximum torque value transmitted by a torque transmitting mechanism disposed inside the first tubular shell and the second tubular shell is regulated.
