    摘要: An impact drill minimizing transmission of vibration to a handle gripped by a user's hand. A spindle extends tends through a main frame and is movable in its axial direction rection and rotatablea about its axis. A first ratchet is rotatable and axially movable together with the spindle. A second ratchet is axially movable but unortatable. The first ratchet has a first serrated surface and the second ratchet has a second serrated surface in confrontation with the first serrated surface. In an impact drilling mode, the first serrated surfaces is brought into abutment with the second serrated surface so that the spindle is reciprocally moved in the axial direction. A spring is interposed between the main frame and the second ratchet to urge the second ratchet toward the first ratchet. In the impact drilling mode, the second ratchet is always out of contact from the main frame and is floatingly maintained within the main frame even if a force ranging from 15 to 25 kg is applied to the main frame toward a workpiece.

    摘要: An impact drill for boring a workpiece includes a main frame, a motor housed in the main frame, a spindle movably supported by the main frame and rotatable by the motor and movable in its axial direction, a first ratchet positioned fixedly with respect to the spindle, a second ratchet positioned with respect to the first ratchet, a spring biasing the second ratchet toward the first ratchet. The spring has at least one of a spring constant and a biasing force which prevents the second ratchet and the spindle from abutting against the main frame at least one of when a force ranging from 15 to 25 kg is applied to the main frame for boring the workpiece and when the spindle is moved to a retracted position.

    摘要: A power tool having a detachable arrangement of an auxiliary handle relative to a main body. The main body has a handle receiving portion. The auxiliary handle has a grip portion and an insertion portion engageable with the handle receiving portion. The insertion portion extends from the grip portion and includes an upper flat surface provided with a protrusion, and a lower arcuate surface. The insertion portion also includes a resilient latch. The receiving portion is provided by a hole having a top flat surface, a lower flat surface and a bottom surface. The top flat surface is formed with an indentation engageable with the protrusion. The base end of the arcuate surface is engageable with the lower flat surface. The lower flat surface is formed with a further recess with which the resilient latch is engageable.
