ABSTRACT:
A string trimmer having a knock-down construction which enables the trimmer to be shipped in a partially disassembled condition and quickly assembled by an end user without the need for special tools and without the need for a large plurality of assembly steps. The string trimmer has a handle assembly having a coupling neck protruding therefrom and a base portion having a coupling neck protruding therefrom. An intermediate assembly has a coupling recess at each of its outermost ends which are adapted to snappingly engage with the coupling necks of the handle assembly and base assembly. Once coupled together, conventional threaded screws and nuts can be used to more permanently fasten the handle and base assemblies to the intermediate assembly. The interlocking coupling arrangements provide a high degree of resistance to twisting and bending forces and yet provide for quick and easy assembly of a new string trimmer by an end user with limited mechanical experience.
