A tool adapter provides an extended stock that can be attached to a hand-held tool, allowing additional force and stabilization input from a user. The adapter may have a stock extending beyond the length of the tool and a body that engages the tool. At least one strap fixes the adapter to the tool. The adapter is removable and can be used on a variety of tools of varying sizes.

A power tool includes a housing, a motor, a spindle, a handle holder and an auxiliary handle. The housing includes a motor housing portion, a drive housing, and a mounting portion between the motor housing portion and the drive housing. The motor is located within the motor housing portion. The spindle is configured to rotate about a rotational axis in response to torque received from the motor. The handle holder is coupled to the drive housing and defines a first mounting point, and the mounting portion defines a second mounting point. The auxiliary handle is selectively attachable to each of the first and second mounting points, and the first mounting point is located at a first position along the rotational axis, and the second mounting point is located at a second position offset from the first position in a direction along the rotational axis.

A method operates a hand-guided working apparatus having a movable working tool installation, a shaft, and a drive motor system. The shaft is designed for moving the working tool installation. The drive motor system is designed for driving the shaft. The working tool installation, the shaft, and the drive motor system at least in part form part of a system capable of rotational oscillation. A controllable oscillation damping installation is designed for damping and/or reducing an excitation of at least one oscillation of the system capable of rotational oscillation and/or excitable by the system capable of rotational oscillation. The method includes: operating the drive motor system to drive the shaft for moving the working tool installation; and controlling the oscillation damping installation during operation such that the oscillation is at least damped and/or an excitation of the oscillation is reduced.

In order to provide a working machine capable of suppressing an increase in size, a working machine that rotates a working tool with motive power of a motor includes a transmission mechanism that transmits a rotational force of the motor to the working tool, a front case in which the transmission mechanism is disposed, a holding tool that is attached to the front case so as to protrude from an outer surface of the case and is gripped by a worker, and an attaching hole which is provided in the front case and to which the holding tool is attached, and the attaching hole penetrates the front case in plan view intersecting with an axis that is a rotation center of the working tool.

A tool unit including a handheld power tool and a side handle mechanically connected to the power tool, wherein the side handle has a threaded rod. The power tool has an undercut groove delimited by a groove bottom, and the side handle has a channel nut engaging the undercut groove, wherein the channel nut has a threaded hole, wherein the threaded rod of the side handle is threadedly engaged in the threaded hole of the channel nut and acts against the groove bottom of the undercut groove. Side handles and power tools for use in such a tool unit are also provided.

The handle for a handheld power tool includes a grip portion which can be gripped by a user, a fastening portion by which the handle can be fastened to the handheld power tool, and an oscillation decoupling device which is designed to decouple oscillations acting on the fastening portion from the grip portion, wherein the oscillation decoupling device has a spring element with a settable spring stiffness

An offset nut driver (“driver”) is implemented which enables machine-generated rotational movement at an input drive to translate to an output spline, and thereby to a socket bit, with minimal user effort. Use of the driver displaces, to a power drill, the human strength element in loosening and tightening bolts. Gears interior to the driver translate the rotational movement from the input drive to the output spline. The input drive may be a hex input rod which can connect to a drill's receptacle, or chuck. The output mechanism may be an output spline to which a socket bit can securely connect. The socket bit can then engage with a nut or bolt for loosening or tightening, in which the rotational torque output by the socket bit is derived from the rotational force exerted against the input rod by, for example, a power drill.

An impact tool (1) includes: a motor (10); an impact mechanism (115), which is rotatable about an output rotational axis (BX) and is operably driven by the motor; an anvil (16) having an anvil shaft (113) disposed forward of the impact mechanism, and a radially-outward-protruding anvil projection (114) that is impacted in a rotational direction by the impact mechanism; a hammer case (6) housing the impact mechanism; an anvil bearing (115) held by the hammer case and surrounding the anvil shaft; a first groove (121) formed on an outer-circumferential surface of the anvil shaft so as to encircle the output rotational axis; a second groove (122) formed on an inner-circumferential surface of the anvil bearing so as to encircle the output rotational axis; and a restraining member (123) having a first portion (124) disposed in the first groove, and a second portion (125) disposed in the second groove.

A power tool system and to a method for connecting a vacuuming device to a power tool. The system comprises a power tool having a tool, a vacuuming device for extracting dust that arises when working with the power tool, and a suction connection device, wherein the suction connection device is arranged between the tool of the power tool and the power tool and is connectable to the power tool in that a toothing of the power tool is able to be engaged with a mating toothing on the suction connection device. The present invention advantageously makes it possible for a suction hose that connects the vacuuming device and the suction connection device of the power tool system together to be able to be fixed relative to a handle of the power tool. Furthermore, an angle between the suction hose and the handle of the power tool can be set particularly easily.

The disclosure relates to a handheld work apparatus, wherein the work apparatus includes a housing, a drive motor for driving a tool, and a handle disposed on the housing. A contour is provided on the handle and a counter contour is provided on the housing. In the inoperative position of the handle, a minimum friction torque (M.sub.1) which acts about the pivot axis is provided between the handle and the housing. In the operative position of the handle, the contour and the counter contour are operatively connected in such a manner that a further friction torque (M.sub.2) which acts about the pivot axis is present between the handle and the housing. The further friction torque (M.sub.2) in the operative position is greater than the minimum friction torque (M.sub.1) in the inoperative position.
