    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 (106), a drive shaft (110) coupled between the electric motor and a cutting instrument (114), and a clutch (108) coupled between the electric motor and the drive shaft. The clutch may include a motor portion (302) having an exterior surface (316), a drive shaft portion (202) having an exterior surface (224) and forming a mated assembly when mated with the motor portion, and a spring (402) 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.
