Auxiliary handle for hand-held tool

Auxiliary handle attachable to a hand-held device, such as a drill, comprising an axially elongated gripping sleeve having an axis, clamping means for fastening said handle on a housing part of a tool, said sleeve being rotatable about the axis thereof, said clamping means including a clamping member for encircling the housing part, said clamping member connected to said sleeve so that by selectively rotating sleeve the clamping member can be clamped on the housing part, said clamping means includes means forming a through guide for an axially elongated rod-shaped depth stop with the axis of said stop extending transversely of the axis of said sleeve, wherein the improvement comprises that said clamping member is a band-shaped member and is looped completely around said housing part and has an inside cross-section so that as said sleeve is selectively rotated, the inside cross-section of said clamping member is reduced and tightens about said housing part, a bearing part separate from said clamping member and arranged to contact the housing part and having at least one through opening for the depth stop, said bearing part being stationary during selective rotation of said sleeve, said through guide of said clamping means being alignable with the through opening of said bearing part and said through guide being displaceable transversely of the axis of the through being displaceable transversely of the axis of the through opening for clamping said depth stop.
