    摘要： A power-tool cutting device includes at least one cutting strand, at least one guide unit configured to guide the cutting strand, and at least one deflecting unit. The guide unit together with the cutting strand forms a closed system. The deflecting unit is arranged on a drive-remote side of the guide unit and has at least one movably mounted deflecting element configured to deflect the cutting strand at least while the cutting strand revolves about the guide unit. The deflecting element includes at least one contact surface for an at least temporary contact with the cutting strand. The deflecting element is configured to be at least substantially free from an extension for engagement in the cutting strand.

    摘要： Embodiments herein provide a modified pitch sprocket to provide an orientation of a saw chain link, such as a cutter link or drive link, with respect to the direction of travel of the link, as it traverses the sprocket that is different than the orientation of the link as it traverses a straight portion of the guide bar. In some embodiments, the modified pitch sprocket may orient the cutter link to provide radial extension for a depth gauge of the cutter link relative to a cutting element of the cutter link. This may facilitate shaping of the depth gauge and/or cutting element, such as by a sharpening element, as the cutter link traverses the sprocket.

    摘要： A power tool for trimming soft materials has a power driver with a drive train engaged with a cylindrical cutter body wherein the power driver rotates the cutter body about its longitudinal axis. A plurality of mutually spaced apart cutter teeth are fixed to an exterior surface of the cutter body. The cutter teeth each have a top surface and a sidewall surface, the sidewall surface extensive between the top surface and an exterior surface of the cutter body. The top surface of each of the cutter teeth is a four-sided convex polygon and the sidewall surface includes four mutually discrete surfaces corresponding to the sides of the polygon, with each of said discrete surfaces extending between the top surface and the cutter body.

    摘要： A saw having a power unit with a drive component and a housing for the power unit with a frame. A bar on the housing guides movement of an operatively positioned cutting chain driven by the drive component in an endless path. The bar is movable guidingly in opposite directions in a predetermined path relative to the housing to thereby vary tension upon an operatively positioned cutting chain. A bar fixing assembly has a knob that is turnable around a first axis relative to the housing in: a) a first direction to a tightened state; and b) a second direction to a loosened state. A first assembly resiliently bears against the knob to at least one of: a) inhibit turning of the knob around the first axis; b) provide a sensory indication to a user grasping and turning the knob that the knob is moving around the first axis; and c) reduce play in the knob.
