The invention relates to a hand-held planing machine (10) comprising a casing (12), a motor and a plane shaft with a plane iron (54) that can be tightened thereto.

A clamp block (80) is mounted on the vertical shaft (78) by a pivot assembly (82).

A tensioning member is mounted on the band.

Said pressing member may be disposed under the operation board either directly or through a fixing member to which the pressing member is fixed.

A barrel assembly includes the barrel clamp tube, a flash suppressor mounted to the front end of the barrel clamp tube, and a barrel clamp co liar mounted to the rear end of the barrel clamp tube.

The device clamp (18) is mounted to the base (16).

The fixture is mounted for tilting by trunnions (124).

The clamping device (10a) is designed as a clamping spring surrounding the bolt (7) and is substantially fixed with regard to the body (3).

The electrode holder (14) is mounted on an electrode support (16) by a clamping mechanism (36).

The device further includes a first clamping member (14) which is slidably disposed with respect to the housing (12).

A spring-loaded, moveable clamping jaw (4) is pivotally mounted on the fixed clamping jaw (3).

An axial bearing (5) can also be mounted between the clamping bush and the clamping body.

The clamping assembly is mounted on the transmission chain (11).

A clamping arrangement (138) is provided in the body.

The clamp spring (2) is designed as a spring ring (2) with a cross slit (3) and serving for clamping around the implant (15) in mounted state by means of said clamping force.
