摘要： The present disclosure relates to a method (100) for production of a chainsaw guide bar (5). The method comprises the steps of providing (120) an elongated core plate (5) extending along a plane, and, in said plane has a length (Lc) in the longitudinal direction (D), and a width (Wc) perpendicular to the longitudinal direction (D), comprising a pair of opposite long side edges (33) and at least one detachable element (31) that extends along at least one of the long side edges of the core plate. Arranging (140) a side plate (23a, 23b) on each side of the core plate (25), thereby forming a sandwiched structure and joining (160) of the plates (23a, 23b, 25) for formation of an elongated guide bar (5), wherein the at least one detachable element (31) remains attached to the core plate (25). The disclosure also relates to a guide bar (5) for a chainsaw (1). The guide bar (5) comprises a laminated structure of at least three layers comprising a first side plate (23a), a second side plate (23b), and a core plate (25) disposed between said first side plate (23a) and said second side plate (23b),wherein the core plate (25) is provided with at least one detachable element (31). The disclosure also relates to an alternative method (200) of production of a chainsaw guide bar (5).

摘要： A lawn care device may include a cutting deck housing at least one blade, a rotatable shaft, and a blade coupler operably coupled to the rotatable shaft. The blade coupler may define a blade channel configured to at least partially enclose four sides of a blade inserted therein. The blade coupler may include a support base and a sleeve that is movable relative to the support base based on a compression state of a biasing element. The blade may be insertable into the blade channel by orienting the blade to apply a force to sidewalls of the sleeve to shift the biasing element to a compressed state and rotating the blade proximate to the support base to enable the biasing element to shift to an extended state in which sidewalls of the sleeve define sidewalls of the blade channel.
