摘要： A power impact tool includes a main body accommodating a chuck at a front end portion thereof; a clutch handle for setting a torque applied to the chuck; a grip including a base portion; a free end portion; and a reinforcing connecting portion connected to the front end portion of the main body at the back of the clutch handle and to the free end portion of the grip. The reinforcing connecting portion is disposed in front of the grip; and a part protruded most forward among the reinforcing connecting portion is located directly in front of the trigger switch disposed at the base portion of the grip. A part of the reinforcing connecting portion disposed behind the clutch handle retreats backward toward the free end portion of the grip.

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.

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.
