A suction device for a power tool, in particular for a drilling and/or chipping tool, has at least one dust container and at least one suction head to be placed on a workpiece, wherein the dust container is integrated in the suction head.

Suctioning device for a machine tool

A wrenchless clamp assembly is provided to secure a tool disc, such as a circular saw blade, to a shaft of a power tool. The blade clamp assembly includes an outer flange positionable against an outer side of the blade and a manually tightenable click bolt that includes a movable click member operable to selectively engage the outer flange for rotationally locking or unlocking the bolt. In an embodiment, the click member moves alternatingly between axially engaged and disengaged positions according to sequential rotational increments of the click member relative to the bolt body. Accordingly, the click bolt can be installed by hand and rotationally locked without a need for high torque, and the click bolt can be easily removed by hand when the click member is moved to the disengaged position, axially free from the outer flange. In an embodiment, the click bolt permits limited torque applied during installation.

Wrenchless blade clamp assembly

The present invention relates to an electric hand tool, in particular a drill or a screwdriver, comprising a housing, an electric motor accommodated therein and having a motor shaft, a tool shaft which is mounted in the housing and which is driven by the motor shaft via a transmission, and a hand-operated locking mechanism for blocking the rotating movement of the tool shaft, wherein this locking mechanism acts on the motor shaft, so that it is possible to suffice with a lesser locking force in order to block the tool shaft with the same locking effect.

Electric hand tool

An apparatus having a foot, a reciprocating saw and a housing. Between the foot and the housing there are means for releasable mounting the foot on the housing, characterized in that the releasable mounting means have a first coupling member connected to the foot and, co-acting therewith, a second coupling member connected to the housing. The coupling members can be carried from a disconnected to a connected position by a relative displacement between the foot and housing.

Assembly of foot and reciprocating saw

A circular saw includes a clutch assembly to surround the rotating blade shaft of the saw. The blade shaft is rotated by a shaft having a gear at one end. The clutch assembly includes a clutch gear to engage with the rotating pinion. The clutch gear is held to the blade shaft by a shaft washer that has a frictional material laminated to one end. The shaft washer is pressed to the clutch gear by spring washers.
