Abstract:

Clamping is provided for a drive shaft tube to a housing that uniformly distributes the clamping forces, eliminating high concentrations of clamping pressure, and accomplishing clamping in an aesthetic manner. A one-piece tubular housing, having an inner surface, for the trimmer head includes a drive shaft component within it. A tubular casing containing a flexible drive shaft has an outer surface for receipt by, and engagement with, the trimmer housing inner surface. A pair of clamping components having an arcuate extent generally comparable to the circumference of the tubular casing inner surface engage the inner surface, and clamp the tubular casing to the trimmer housing inner surface by the action of a pair of screw fasteners having heads exterior of the first housing, and threaded shanks extending into threaded engagement with openings in the inner clamping components.
