Abstract
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.
