<p>A power tool having a housing divided into two parts (10, 11) interconnected by a thread joint (23) comprising a internal threads (28, 29) on the housing parts (10, 11) and a tubular connection element (24) with two external axially spaced thread sections (26,27) for engagement with the threads (28, 29) on the housing parts (10, 11), wherein the connection element (24) comprises a thin walled waist section (23) located between the thread sections (26, 27) and intended to provide a certain elastic deformation as a tightening torque is applied on the thread joint (23) to thereby increase the clamping length of the thread joint (23), and a resilient ring (35) carried on the waist section (23) and arranged to be elastically deformed by squeezing between the housing parts (10, 11) and the connection element (24) at tightening of the thread joint (23) thereby providing a rotation locking friction force on the thread joint (23).</p> |
