摘要： A gardening trimmer may include: a conversion mechanism for converting rotational motion of a prime mover to linear motion along a first direction; a blade for moving in reciprocating motion relative to a guide bar and including a plurality of slots; and a plurality of guide members each disposed in a corresponding slot of the plurality of slots of the blade. The plurality of slots may include: at least one first slot in which a corresponding guide member of the guide members that is connected to a housing is disposed. A combination of the slots and the guide members may include: a first combination to reduce frictional resistance generated by the reciprocating motion; and a second combination to reduce vibration generated by the reciprocating motion, and at least one combination of the at least one first slot and its corresponding guide member is the second combination.

摘要： 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.
