Abstract
A gardening trimmer may include a first blade configured to be driven by a prime mover in a reciprocating manner along a first direction and a guide disposed in a slot of the first blade to guide reciprocating motion of the first blade. The slot includes first and second inner side surfaces opposing each other and extending along the first direction. The guide includes an outer peripheral surface opposing the slot's inner side surfaces. The outer peripheral surface of the guide includes a first portion in contact with the first inner side surface and a second portion in contact with the second inner side surface. The outer peripheral surface of the guide is curved at least at the first and second portions, and curvature radii of the first and second portions are each greater than a half of a distance between the first and second inner side surfaces.
