摘要: An impact tool for simultaneously providing a rotational force and an impact force to an object has an output shaft rotated by a motor, hammer for intermittently providing an impact force to the output shaft, hammer holder for movably holding the hammer, and an impact force generator for generating the impact force from an output of the motor. An air chamber is formed between the hammer and the hammer holder such that a volume of the air chamber is variable in response to a position of the hammer relative to the hammer holder. In addition, the hammer receives a bias force generated in a direction toward the output shaft by a biasing device. This bias force effectively increases the impact force in cooperation with an air pressure caused by a volume change of the air chamber.

摘要: A hammer drill includes a motor; a spindle rotatingly driven by the motor and holding an output bit; a motion conversion member for converting rotational movement of the motor to reciprocating movement; a striker reciprocatingly driven by the motion conversion member for applying an axial striking force to the output bit; a striking-motion-releasing mechanism for releasing the striking force applying action exercised by the striker; and a tightening-torque adjusting clutch for interrupting the transfer of the rotational force to the output bit by increasing a load torque.

摘要: A power impact tool adapter, for use in installing a bit to be used in a striking-motion-deactivated mode to a power impact tool, includes an SDS type shank portion to be held by a chuck; closed grooves to be mated with sprung balls to prevent the release of the bit; and slide grooves to be slidably mated with wedges applying a rotational force to the bit. An axial length of each slide groove is shorter than that of a slide groove of a standard SDS shank such that the end of the shank portion is prevented from contacting a striking member of the power impact tool which applies a striking force to the bit.
