摘要： A power tool includes an elongated shaft forming a handle constructed of a non-conductive material and a tool head located at one end of the handle. The tool head includes a working element and a driven shaft configured to drive the working element. A powerhead located at an opposite end of the handle and includes an input shaft. A driveshaft extends between the tool head and the powerhead. The driveshaft is rotatably coupled to the input shaft and the driven shaft to transfer torque from the powerhead to the working element of the tool head. At least a portion of the driveshaft extending between the powerhead and the working element is constructed of a non-conductive material to inhibit transmission of electricity from the working element to the powerhead.

摘要： A power tool includes an elongated shaft forming a handle and a tool head located at one end of the handle. The tool head includes a working element and a driven shaft configured to drive the working element. A powerhead located at an opposite end of the handle and includes an input shaft. A driveshaft is coupled between the tool head and the powerhead. The driveshaft has a first driveshaft portion rotatably driven by the input shaft and a second driveshaft portion coupled to the first driveshaft portion and the driven shaft. The second driveshaft portion is driven by the first driveshaft portion to transfer torque from the powerhead to the working element. One of the first driveshaft portion or the second driveshaft portion is constructed of a non-conductive material or both of the first driveshaft portion and the second driveshaft portion are constructed of a non-conductive material.

摘要： A telescoping tool includes a pole assembly, a driveshaft, a plurality of bearings, and at least one connection member. The pole assembly includes an outer pole and an inner pole. The inner pole is slidably received in the outer pole. The pole assembly is movable between a retracted configuration and an extended configuration. The driveshaft extends longitudinally in the outer pole and the inner pole. Each bearing of the plurality of bearings includes a driveshaft passage defined therein. The driveshaft passage receives the driveshaft therethrough. Each bearing further includes an end connection passage defined therein. The at least one connection member joins adjacent bearings of the plurality of bearings. The at least one connection member is disposed in the end connection passage of each of the adjacent bearings.

摘要： A power tool includes a main housing having a pair of clamshells, each of which has a mating face and a blind bore within the mating face. The power tool further includes a motor having a front bearing retainer, a plurality of fasteners configured to secure the front bearing retainer within the main housing, and a pin received within the blind bores of the respective clamshells, such that each of the clamshells is inhibited from moving with respect to the other clamshell. The power tool further includes an output assembly having an anvil with an output member configured to engage a socket and a pawl that is moveable between a first position in which the pawl is operatively coupled to drive the anvil in a first direction and a second position in which the pawl is operatively coupled to drive the anvil in a second direction.

摘要： A blade clamp, for use with a power tool having a reciprocating spindle, includes a cover rotatably coupled to the spindle and a detent received within a bore of the spindle. The detent is movable in a radial direction relative to a longitudinal axis of the spindle to adjust the blade clamp between a locked configuration and an unlocked configuration. The cover is rotatable between a first rotational position relative to the spindle coinciding with the locked configuration, and a second rotational position relative to the spindle coinciding with the unlocked configuration. The blade clamp further includes a sleeve in which the detent is slidably received. The sleeve includes a non-corrosive material for inhibiting corrosion of the detent.

摘要： A drain cleaner includes a handle assembly with a grip, a motor supported by the handle assembly, and a shroud coupled to and extending forwardly from the handle assembly. The shroud includes a closed end facing the handle assembly and an open end facing away from the handle assembly. The drain cleaner also includes a drum assembly rotatably coupled to the handle assembly and positioned within the shroud. The drum assembly is operable to be rotated by the motor relative to the handle assembly and the shroud. The drain cleaner further includes a flexible cable stored within the drum assembly. The drum assembly encloses the flexible cable.

摘要： A power tool includes a switch moveable between a first position enabling activation of a motor and a second position disabling the motor. The power tool includes a trigger movably coupled to a housing of the power tool between an OFF position and an ON position. The switch moves from the second position to the first position in response to the trigger moving from the OFF position to the ON position. The power tool includes a trigger lock-off pivotably coupled to the housing between a lock position and an unlock position. The trigger lock-off is engageable with the trigger to inhibit movement of the trigger from the OFF position to the ON position when the trigger lock-off is in the lock position. The trigger lock-off allows movement of the trigger from the OFF position to the ON position when the trigger lock-off is in the unlock position.
