摘要： An impact tool capable of improving durability of tool components and capable of reducing noise and vibration is provided. The impact tool includes a housing, a motor, a motion converting portion, an output portion, a power supply portion, a load detecting portion, and a control portion. The motor is disposed in the housing. The motion converting portion is configured to convert a rotating motion of the motor into a reciprocating motion. The output portion is configured to output the reciprocating motion of the motion converting portion as an impact force. The power supply portion is configured to supply a driving power to the motor. The load detecting portion is configured to detect a load imposed on the motor. The control portion is configured to control the power supply portion to increase the driving power supplied to the motor during a prescribed period when the load detected by the load detecting portion is larger than a prescribed value.

摘要： A power tool which has an anvil 20 that is rotated by a hammer 22 and is housed in a housing, and rotates an output shaft 18 is provided. The anvil 20 and the output shaft 18 are integrally formed into one unit, and a carrier 33 that is rotatable relative to the anvil 20 by a predetermined angle on the same axis is provided. On one portion of an outer circumferential surface of the anvil 20, a relief surface 20a is formed. Cut-out portions 33b are formed at positions opposed to each other of a carrier 33, and by allowing an engaging pin 37 to be interposed therein, a locking mechanism that limits the relative rotation between the anvil 20 and a lock ring 38 is prepared. When the tool main body is manually rotated while the hammer 22 is being stopped, the engaging pin 37 limits the relative rotation between the anvil 20 and the lock ring 38. The locked state between the anvil 20 and the lock ring 38 is released immediately when the rotation of the motor 4 is started.

摘要： An impact tool includes a motor, a hammer, an anvil, and a control unit. The hammer is configured to be driven by the motor and be movable in an axial direction of the motor. The anvil is configured to be struck by the hammer. The control unit is configured to control a rotation of the motor. The impact tool further includes a restricting unit configured to restrict the movement of the hammer in the axial direction. The control unit is configured to select a driving mode of the motor between a first mode and a second mode. The control unit selects the first mode when a load of the motor is less than or equal to a prescribed value regardless of a restriction of the restricting unit, whereas the control unit selects the second mode when the load exceeds the prescribe value and the restricting unit restricts the movement of the hammer.
