摘要： Embodiments herein describe presets for saw chains comprised of one or more rivets that are coupled to a tiestrap. Each rivet may further comprise a central flange and a hub protruding from opposed sides from the flange. In some embodiments, the hub may be non-concentric from the flange, and the flange may be non-circular, such as ovoid or cam-shaped. In some embodiments, various portions of the flange, rivet, and tiestrap may be selectively hardened to various degrees of hardness, depending upon their location and usage. In some embodiments, the rivets may be prevented from rotating with respect to the tiestrap using a brazing process, and may be configured to facilitate such processes. Other embodiments may employ a non-circular hub. Still other embodiments may use a low-temperature process for soldering that does not affect the hardness of the tiestrap or rivet.

摘要： Embodiments of a pole-attached power tool system, and related methods, are disclosed herein. In some embodiments, a pole-attached power tool system may include a pole having a first end, a second end, and an interior region; a handle disposed proximate to the first end of the pole; an electric motor disposed proximate to the first end of the pole; a power tool disposed proximate to the second end of the pole; and a drive member disposed within the interior region, the drive member mechanically coupled with the electric motor and the power tool to transfer power generated by the electric motor to the power tool.

摘要： Embodiments of clutches for electric tools, and related methods, are disclosed herein. An electric tool may include an electric motor, a drive shaft coupled between the electric motor and a cutting instrument, and a clutch coupled between the electric motor and the drive shaft. The clutch may include a motor portion having an exterior surface, a drive shaft portion having an exterior surface and forming a mated assembly when mated with the motor portion, and a spring around the motor and drive shaft portions. The spring may exert a holding force on the mated assembly, such that rotation of the motor portion in a first direction loosens the spring and reduces the friction holding force until a torque between the motor and drive shaft portions exceeds the holding force, causing rotation of the motor portion to be decoupled from rotation of the drive shaft portion.
