摘要： A pneumatic percussive tool for a paving breaker and/or a hammer drill, provided with a drive piston (1) which is axially displaceable both backwards and forwards, comprising a guide sleeve (4) and a piston bottom (5) supporting the guide sleeve (4). A percussion piston (7) can be displaced axially in the guide sleeve (4) of the drive piston (1) with the piston head thereof in percussive mode. During the transition from percussive to idling mode, the piston head (8) slides out of the guide sleeve in such a way that the percussion piston (7) is substantially maintained in the idling mode in an axially displaceable manner by means of a stationary part of the percussion tool housing (10,16) as opposed to being so maintained in the guide sleeve (4). The axial length of the drive piston (1) can be reduced, whereby the mass of the drive piston and vibrations caused by the movement of the drive piston (1) in the percussive and idling mode can also be reduced.

摘要： A secondary hammer support structure in a rotary impact tool 1 is structured such that a plurality of steel balls are disposed between a secondary hammer 21 and a retaining member 18. The plurality of steel balls 17 are arranged between the first retaining groove 21g of the secondary hammer 21 and the second retaining groove 18a of the retaining member 18. The retaining member 18 is formed as a member separate from the spindle 11 and has a retaining surface for retaining steel balls 17 and a mounting surface mounted to the spindle 11 so as not be rotatable. The mounting surface of the retaining member 18 is mounted to a front member of a carrier 16.

摘要： In order to provide an impact tool which is capable of increasing a striking force in a rotational direction of being applied from a hammer to an anvil, the impact tool includes: an electric motor; an anvil (27) which supports a work tool and is driven by the electric motor; and a hammer (43) which applies the striking force in the rotational direction to the anvil (27). The impact tool is provided with: a spindle (40) which is arranged to be concentric with the anvil (27), supports the hammer (43) to be movable in an axial direction and the rotational direction with respect to the anvil (27), and transmits motive power of the electric motor to the anvil (27); and a control unit which controls rotation speed of the electric motor. The number of strokes of the anvil (27) due to one rotation of the hammer (43) differs in response to rotation speed of the electric motor.

摘要： An electrical hammer (100) comprises a main housing (101), a hand grip (500) connected to the main housing (101) via a compression coil spring (321). In the electrical hammer (100), a hammer bit (119) is driven by a first motion converting mechanism (120) and thereby a hammering operation is performed. During the hammering operation, the hand grip (500) is moved against the main housing (101) in a state that biasing force of the compression coil spring (321) is applied on the hand grip (500). Further, the electrical hammer (100) comprises a second motion converting mechanism (220) which drives a counterweight (231).
