Interchangeable garden tool mounting - has quick release coupling with tensioning casing around sleeve and radially sprung holding element

摘要

A number of implements can be fitted to one shaft and shaft and implements are connected by a manual quick-release coupling. This coupling consists of a female coupling sleeve, a radially movable holding element and a male coupling nipple with a fixed engagement face for the holding element. A tensioning casing which encloses the coupling sleeve has an inclined surface, the relative movement of which with respect to the coupling sleeve allows the holding element to move radially. The holding element itself is under radially outwards spring pressure.
