Apparatus for fastening a handle on a power tool

A power tool comprising:

• a device configured for positioning and fastening to said power tool, said device comprising:
• a handle;
• a mount connected to the handle and adjustable between a positioning setting and a fastening setting, the mount configured to receive the power tool along a mount axis extending longitudinally through the mount;
• a clamping device configured for fixing said mount in either of said positioning setting or said fastening setting;
• and
• an axial securing element being provided at said power tool to secure said power tool and said device relative to each other in an axial position along the mount axis in each of the positioning setting and the fastening setting of said mount;
• wherein said mount has a first detent element which is co-operable with a second detent means element provided at said power tool, the first and second detent elements configured to set different angular positions of said device with respect to said mount axis;
• wherein said first detent element comprises at least two longitudinal ribs extending parallel with the mount axis and said second detent element comprises at least two longitudinal ribs extending parallel with the mount axis;
• wherein, in one angular position of said device with respect to said mount axis, one longitudinal rib of said second detent element is received with positive engagement between two longitudinal ribs of said first detent element, and in an immediately adjacent angular position of said device with respect to said mount axis, two longitudinal ribs of said first detent element are received with positive engagement between two longitudinal ribs of said second detent element.
