<p>A portable grinding machine ( 10 ) includes an elongated housing ( 12, 14 ) and an output shaft ( 16 ) projecting at a right angle to the housing axis for receiving a disk-shaped rotary clamping tool. The output shaft is encompassed by a substantially cylindrical clamping collar ( 30 ), on which a shell-like protective cover ( 20 ) is secured in a tensile manner against rotation and axial displacement and which serves for encompassing the clamping tool ( 18 ) and which can be attached on the clamping collar ( 30 ) with a ring-shaped tensioning belt ( 28 ). The tensioning belt ( 28 ) has sharp-edged projections ( 32 ) projecting to the clamping collar, which upon clamping, born into the clamping collar and are held there in a form-locking manner (a shell-like tensioning band).</p> |
