A holding apparatus for being detachably attached to a machine tool housing of a machine tool and for receiving a hook for hanging the machine tool from the hook is provided. The holding apparatus has a fastening portion for fastening the holding apparatus to the machine tool housing, a securing device for securing the holding apparatus on the machine tool housing, and a receiving portion which has an opening and is intended for receiving and rotatably supporting an insertion portion of the hook, the receiving portion defining an axial direction. The fastening portion has a first interlocking connector to engage with a first mating interlocking connector provided on the machine tool housing, the interlocking connection between the first interlocking connector and the first mating interlocking connector allowing movement of the holding apparatus in a sliding direction and preventing movement perpendicular to the sliding direction, and in that the securing device can be moved between an open position and a locked position, the securing device being designed to prevent the holding apparatus from moving in the sliding direction in the locked position and to allow movement in the open position.

A battery-powered hand-held machine tool, particularly a hand-held circular saw, includes an electric motor for rotational driving a tool arranged on the hand-held machine tool, particularly a saw blade, a front handle and a rear handle each in terms of an advancing direction of the hand-held machine tool, and a receiving recess for receiving a replaceable battery. The rear handle is mounted such that it can pivot out, preferably upwards, about a pivot axis such that when the rear handle is in a state of being pivoted out, the receiving recess for receiving or removing the replaceable battery is exposed and, when the rear handle is in a state of being pivoted in, the reception or removal of the replaceable battery into or out of the receiving recess is blocked.

Battery-powered hand-held machine tool

A device for accommodating at least one battery on a power tool, in particular a circular saw, including a receiving plate for detachably holding the at least one battery, including at least one contact device for connecting the battery to the power tool, and a double hinge device having a first and a second rotation axis, the first rotation axis being positioned on a housing of the power tool, and the second rotation axis being positioned on the receiving plate, so that the receiving plate is reversibly pivotable around the first and the second rotation axis relative to the housing between a first and a second position.

A device for setting the miter angle of a machine tool is disclosed. The device includes a clamping block having at least one slot, and a pivot lever on which the machine tool can be mounted and which is pivotable about a pivot point relative to the clamping block between a minimum and a maximum miter angle. The slot includes at least two stop elements offset relative to one another. A setting mechanism includes a lever element for the selection of a maximum miter angle, where the lever element includes a mating stop element is alignable in such a way corresponding to the rotational alignment of the lever element that the mating stop element is able to strike the respective stop element in accordance with the selected maximum miter angle and by which the pivoting movement of the pivot lever relative to the clamping block can be limited.

A drive shaft for a machine tool is connectable to a drilling tool. The drive shaft contains a cavity extending substantially over the entire length of the drive shaft and along the axis of rotation where the cavity contains an inflow opening through which water can be fed along the drive shaft into the drilling tool. An insert device is provided in the cavity, through which, to cool the drive shaft, the water is guided first in a first direction and then in a second direction where the insert device contains a first curved guide element and a second curved guide element for separating the water which is guided in the first direction from the water which is guided in the second direction. The cross-sectional area of the first curved guide element is designed point-symmetrically about a center longitudinal axis to the cross-sectional area of the second curved guide element.

A hand machine tool includes a tool retainer that retains a tool, a motor that drives the tool retainer in a rotary motion, and a torque-controlled sliding clutch that is connected in a drivetrain between the motor and the tool retainer. The sliding clutch includes a first clutch disk, a second clutch disk, a spring and a controlling unit which can be activated manually. The second clutch disk is arranged displaceably alongside an axis limited by a stop in the direction toward the first clutch disk. Force is applied to the second clutch disk by the spring alongside the axis in the direction toward the first clutch disk. The manually activated controlling unit variably sets an axial distance between the first clutch disk and the stop, with which an engagement depth of the first clutch disk with the second clutch disk can be defined.

A hand-operated jigsaw is disclosed. The reciprocating drive mechanism has a reciprocating body which can be put into a reciprocating motion along an axis via an eccentric of an eccentric wheel that can be set in motion by the motor. The eccentric wheel is arranged on a pivot bearing axis. The reciprocating drive mechanism has an additional mass with a mass center of gravity to minimize vibrations. The additional mass is arranged in a rotationally fixed manner with the eccentric wheel on the pivot bearing axis. An eccentric axis of the eccentric lies on a first radial of the pivot bearing axis, which is offset from a second radial in the operating direction of rotation of the eccentric wheel at an angle of between 190&#xb0; and 270&#xb0;, which second radial lies between the mass center of gravity of the additional mass and the pivot bearing axis.
