摘要： Disclosed is a torque-adjustment controller for use with a tool to safely adjust and control the torque the tool works on a workpiece. The torque-adjustment controller mainly consists of a housing, an output shaft, an input shaft, a stepped ring, a lugged movable member contacting the stepped ring, a torque spring disposed between the output and the input shafts. The output shaft has recesses to engage with steel balls contained on the input shaft so that force exerted on the input shaft by a tool may be transmitted to the output shaft via the engagement of the steel balls with the recesses of the output shaft. The stepped ring has multiple sets of steps providing different head drops and will cause the lugged movable member contacting it to shift axially when the stepped ring is rotated. The axially shifted movable member will further compress the torque spring to generate stronger torque or release the torque spring for the same to generate weaker torque. Such adjusted torque is transmitted from the input shaft to the output shaft to work on a workpiece to safely protect the latter from being damaged due to improper torque of tool.
