摘要： Tightening tools is provided with a pair of clutch members disposed between a motor and a tool bit. The pair of clutch members is provided with a first engaging portion and a second engaging portion. The first engaging portion is constructed so as to disengage the pair of clutch members when the torque applied to the tool bit is equal to or above a first predetermined value. The second engaging portion does not engage the pair of clutch members while the first engaging portion engages the pair of clutch members and the second engaging portion engages the pair of clutch members after the first engaging portion disengages the pair of clutch members. The second engaging portion is constructed so as to disengage the pair of clutch members when the torque applied to the tool bit is equal to or above a second predetermined value. The second predetermined value may be different from the first predetermined value.

摘要： While a load torque applied to a tool shaft is lower than a predetermined value, a moving member is maintained at a first position, and a sun gear is rotated integrally with an internal gear. When the load torque applied to the tool shaft reaches or exceeds the predetermined value, the moving member is moved to a second position, to thereby prohibit relative rotation of the internal gear and a gear case. A latch member is engaged in a catching portion of the moving member when the moving member is moved to the second position, to thereby prevent the moving member from moving back to the first position. In this manner, repetitive switching between speed reduction ratios can be prevented even when the load torque applied to the tool shaft fluctuates.
摘要翻译：当施加到工具轴的负载扭矩低于预定值时，移动构件保持在第一位置，并且太阳齿轮与内齿轮一体地旋转。当施加到工具轴的负载扭矩达到或超过预定值时，移动构件移动到第二位置，从而禁止内齿轮和齿轮箱的相对旋转。当移动构件移动到第二位置时，闩锁构件接合在移动构件的捕获部分中，从而防止移动构件移回到第一位置。以这种方式，即使当施加到工具轴的负载转矩波动时，也可以防止减速比之间的重复切换。

摘要： It is an object of the invention to provide an effective technique for avoiding the influence of reaction during tightening operation in the rotary fastening tool. Representative rotary fastening tool includes a tool body, a motor housed within the tool body, a driving-side rotating member that is rotationally driven by the motor, a driven-side rotating member that is disposed coaxially with the driving-side rotating member, a tip-end side rotating member that is disposed coaxially with the driven-side rotating member and rotationally driven via the driven-side rotating member, the tip-end side rotating member driving a tool bit to perform a tightening operation and a rotation control mechanism that allows the tip-end side rotating member to rotate in the tightening direction during the tightening operation of the tool bit, wherein, when the tip-end side rotating member is fixed to a workpiece with the tool bit during the tightening operation and when torque transmission from the driving-side rotating member to the driven-side rotating member is interrupted, the rotation control mechanism locks the tip-end side rotating member and the tool body together against rotation with respect to each other to prevent the tool body from rotating in the tightening direction.
