摘要：Disclosed is a safety coupling in a percussion hammer and/or drill hammer,comprising a basic sleeve (20), a driven toothed wheel (21) that is rotatably mounted onthe basic sleeve (20) and can be driven by a drive unit, a closing ring (27) which is fastenedto the basic sleeve (20), and a locking ring (28) located between the driven toothed wheel(21) and the closing ring (27). Said locking ring (28) is fixed in a torsion-proof mannerrelative to the closing ring (27) while being movable relative to the closing ring (27) in anaxial direction, counter to the effect of a spring mechanism (29). The locking ring (28) isaxially displaced while the driven toothed wheel (21) remains in the axial position thereofwhen a threshold torque is exceeded.
