发明名称 Tool assembly
摘要 A surface-working tool assembly having a surface-working tool connected by a quick releasable coupling to an elongate handle member. One portion of the coupling is connected to the tool and the other is connected to the handle. The tool portion is connected by a universal joint permitting rotational movement about first and second perpendicular axes. A female portion of the connecting means includes first and second telescopically engaged sleeves, the inner sleeve having a tubular passage and radial openings containing locking elements movable into and out of blocking relationship in the tubular passage. The outer sleeve is movable from a position holding the locking elements of the inner sleeve in blocking relationship to the tubular passage, to a second position where an inner annular recess is aligned with the locking elements to permit movement thereof out of blocking relationship to the tubular passage wherein a shank member of the male portion of the coupling means can be inserted and withdrawn from the tubular passage. The shank member has a reduced diameter portion which can be situated in alignment with the radial openings of the inner sleeve so that the locking elements are movable into position around the neck to hold the shank member releasably connected to the inner sleeve and locked in that position when the outer sleeve is moved to a position preventing movement of the locking elements out of the tubular passage.
