A clamp arrangement for securing an accessory to an oscillating power tool can include a clamp assembly including a first clamp member that moves relative to the accessory between a closed position wherein the clamp assembly retains the accessory and an open position wherein the first clamp is offset from the accessory permitting removal of the first accessory from the clamp assembly. The clamp assembly can further comprise a second clamp member having a first portion that opposes the first clamp member and cooperates with the first clamp member to clamp the accessory between the first and second clamp members. An attachment plate can carry the clamp assembly. The attachment plate can have a first mating detail formed thereon that is configured to selectively and removably mate with a complementary second mating detail on the power tool in an assembled position.

A holder assembly for a circular saw tool includes a blade having a bore. The blade is mountable to a free end of a rotatable shaft or of the tool through the bore. The blade is further adapted to be held in a pressing manner between an inner flange and an outer flange on the shaft. The holder assembly is comprised of at least one depression formed on a circumferential surface of the free end of the shaft, and at least one clutch member (or dogs) paired and mounted about the at least one depression, and located between the bore of the blade and the shaft. The holder assembly provides improved gripping while safety or emergency braking.

A power tool includes a housing, a spindle, a clamp shaft, a first biasing member, an engagement member, a first holding member, a manually operable member and a push-down member. The first biasing member biases the clamp shaft upward. The first holding member holds the engagement member to be movable between a first position and a second position in the up-down direction relative to the first holding member. The manually operable member moves a first one of the engagement member and the first holding member downward in response to a manual unclamping operation. The engagement member moves from the first position to the second position to be movable in the radial direction in response to the manual unclamping operation. The first one of the engagement member and the first holding member pushes down a tool accessory via the push-down member while the first one is moving downward.

The invention relates to a machine tool, in particular a hand held machine tool, which has a tool receiving device that is movable, in particular in an oscillating manner, around an output shaft. The tool receiving device is designed to hold a tool device on the machine tool in such a manner that the output shaft and a tool rotation axis substantially coincide. The tool receiving device has at least one torque transmission region and a holding device. In order to transmit a driving force to the tool device, the torque transmission region has at least two output area regions that are arranged at a distance from said output shaft and each have a multiplicity of surface points. Here, the tangent planes to said surface points are inclined in regard to an axial plane which includes said output shaft. Furthermore, the tangent planes are inclined in regard to a radial plane which extends perpendicularly to the output shaft. In this way, the output torque is transmitted reliably to the tool device by the machine tool via the tool receiving device.
