Coupling element for a manually guided electronic tool

摘要

In order to produce and release the positive connection between a drive shaft and the power output shaft of a manually guided electric tool, coupling elements are known which contain a coupling sleeve which is arranged on the drive shaft in an axially displaceable, but non-rotatable fashion, on which coupling sleeve an integrally formed sleeve which is subject to the action of a restoring spring is seated. An actuator which can be actuated by means of a handle acts on the said slide. It has been found that during the displacement process the slide is prone to jamming and, as a result, at least makes the cutting process more difficult. In order to eliminate this disadvantage, it is proposed that the slide (1) be realised by means of at least one annular washer (3) which is seated loosely on the coupling sleeve (5) and one spacing bushing (2) which holds this annular washer at a distance from a second annular part (4) which is also arranged loosely on the coupling sleeve, and that the compression spring (10) act on the loose annular washer (3).
