摘要： The torque spanner consists of a flexible actuating arm (14) and a rigid arm (18) joined at one of their ends and carrying a driving piece (10). The first arm is provided at its free end with an adjustable indexation (34) retaining a tilting finger (26) which pivots on the second arm (14) and is biased towards the indexation by a spring (48). The flexible arm, when subjected to a torque, flexes so that the indexation retainer (34) exerts a force against the tilting finger (26) until the torque becomes great enough for the two parts to become disengaged and the tilting finger (26), due to the effect of its spring (48) pivots to hold the indexation retainer angularly disengaged. The indexation is retractable between a position of retention of the finger (26) and a retracted position to allow the return of the finger (26) back to a position of re-engagement of the flexible arm (14). Guidance (30,54,58 to 62) is provided on the rigid arm (18) to aid the finger (26) to return to its original position.

摘要： A two-speed fastener driving tool includes a reversible rotary motor including means to reverse, having an output shaft connected in axial alignment with a tool driving output shaft by an improved drive assembly comprising a first overrunning clutch axially aligned with the motor output shaft for providing a high speed drive connection with the tool driving output shaft when the motor is rotated in a first direction. A second overrunning clutch surrounds the first overrunning clutch and functions for providing a low speed drive connection with the tool driving output shaft when the motor is rotated in a direction opposite to the first direction.

摘要： Disclosed is a fastening tool equipped with a rotatively hitting mechanism comprising a cylinder disposed crossing a rotary axle of an anvil shaft at a right angle, a piston mounted slidably on and engaged with the cylinder, an oil passage communicating the inside of the cylinder with the outside of the anvil shaft, a rolling member disposed rolling along an inner wall surface of a rotating liner while being pressed with an elastic member, and a projection portion formed swelling inwardly on the inner wall surface of the rotating liner so as to hit the rolling member. The rotatively hitting mechanisms are disposed in plural numbers and at plural stages in a manner concentrically to each other, and the plural rotatively hitting mechanisms are disposed in a position relationship rotationally symmetrical to each other. An exhaust opening is disposed at a location nearby a body portion of the rotatively hitting mechanism.

摘要： An object is to improve accuracy of tightening torque and to shorten time necessary for fastening a screw in an impact type screw fastening device that uses an electric motor as a rotation driving source. A control method for the impact type screw fastening device that uses an electric motor as a rotation driving source includes the steps of driving the motor to rotate by supplying current to the motor intermittently so that torque exerted on a load by rotation of the motor becomes like pulses on the time axis, and controlling the current of every time of each pulse so that an increment of every time of each pulse of the torque after the torque reaches a target approach torque TQN that is a first set value becomes smaller than that before it reaches the target approach torque TQN.
