Methods and apparatus for a chipping hammer adapter handle generally comprising an elongated shaft and a hammer receiver. The elongated shaft is coupled to the hammer receiver. The hammer receiver comprises a hammer handle housing configured to receive a chipping hammer handle, and at least one secure arm to secure a chipping hammer. The adapter handle further comprises a knee guard and at least one vacuum hose guide. The adapter handle allows a user to remain in a standing position while using a chipping hammer for tile removal. The more ergonomic position may prevent fatigue and health issues for the user.

An improved technique relating to mounting of a battery in an impact tool which has a handle configured to move with respect to a tool body. A hammer drill has a body, a handle part and a battery mounting part. The handle part is configured to slide with respect to the body under a biasing force of a coil spring. The battery mounting part has a plurality of mounting parts. At least one of the mounting parts of the battery mounting part is connected to the handle part and slides together with the handle part with respect to the body during operation.

A nail punching machine for driving in or pulling out rail spikes comprises a driving mechanism, which is driven by means of an electric drive motor. The electric drive motor is supplied with electric power by means of an accumulator. The nail punching machine is held by an operator by means of at least one handle.

A nail punching machine for driving in or pulling out rail spikes includes a driving mechanism, which is driven by an electric drive motor. The electric drive motor is supplied with electric power by an accumulator. The nail punching machine is held by an operator by at least one handle.

A rotary hammer selectively operates in multiple modes including a first mode and a second mode. The rotary hammer includes a switch, a motor, a switch manipulation member, a locking member, and a mode detecting device. The switch manipulation member includes a body, and a protrusion that is movable between a protruding position and a retracted position. The body houses a solenoid configured to operate based on a detection result of the mode detecting device. The locking member is movable between an unlock position and a lock position where the locking member holds the switch manipulation member in an ON position by abutting the protrusion in the protruding position. The protrusion is integrated with a plunger of the solenoid. The protrusion is configured to be in the protruding position when the present mode is the first mode, and in the retracted position when the present mode is the second mode.

A powered hammer assembly includes a powered hammer including an output shaft and an axial impact mechanism. The assembly also includes an attachment including an impact portion defining a first axis. The impact portion is fixed to the body and is immovable relative to the body. The impact portion is configured to receive repeated impacts from the powered hammer. The attachment further comprises a receiving portion in which a rod to be driven into the ground is receivable. The clamping portion defines a second axis that is parallel with the first axis.

A percussion tool includes a housing having a top end, a bottom end, a front end, and a rear end. The housing defines a barrel portion, a handle portion opposite the barrel portion, and a motor housing portion between the barrel portion and the handle portion. The percussion tool also includes an electric motor positioned within the motor housing portion and a percussion mechanism driven by the motor and including a striker supported for reciprocation in the housing. The striker defines a striker axis in a reciprocating direction. The percussion tool further includes a battery receptacle supported by the housing and a battery pack removably coupled to the battery receptacle for providing power to the motor. The battery pack and the battery receptacle define a battery axis extending longitudinally through the battery pack and battery receptacle. The striker axis and the battery axis are parallel.

The present disclosure provides a pneumatic tool with shock absorber. The pneumatic tool has a main body which is adapted for an air supply to be connected thereto. With the air supply, a striker disposed in the main body reciprocates to generate impulse and vibration. A damper, including an elastic member and an airtight compartment, is disposed at the rear end of the reciprocation path of the striker. Therefore, the elastic member and the airtight compartment can absorb the shock produced backwardly by the striker. The vibration and the noise can be reduced for avoiding occupational injury caused thereby.

A hand-held power tool includes a tool holder for holding a chiseling tool, a machine housing (16), and a striking mechanism (12) including a striking body (22) moved on a longitudinal axis (5) for exerting strikes on the tool in an impacting direction. A damper (23) is used for stopping the striking body (22). The damper (23) includes a ring made up of multiple elastic beads situated along a circumferential direction around the longitudinal axis (5).
