Abstract: A rotary power tool comprises a drive mechanism including an electric motor and a transmission, a housing enclosing at least a portion of the drive mechanism, a spindle rotatable in response to receiving torque from the drive mechanism, a first ratchet coupled for co-rotation with the spindle, a second ratchet rotationally fixed to the housing, a sleeve bushing on an interior of the housing, and a bearing arranged between the spindle and the sleeve bushing and rotatably supporting the spindle. The bearing has an outer race. The spindle is movable relative to the housing in response to contact with a workpiece, causing the first and second ratchets to engage and the spindle to reciprocate while rotating. The outer race of the bearing moves along the sleeve bushing during reciprocation of the spindle when the first ratchet and second ratchet are engaged.

Abstract: An impact tool includes a housing, a motor having an output shaft defining a first axis, a drive shaft rotatably supported by the housing about a second axis oriented substantially normal to the first axis, and an impact mechanism coupled between the motor and the drive shaft and operable to impart a striking rotational force to the drive shaft. The impact mechanism includes an anvil rotatably supported by the housing and coupled to the drive shaft, and a hammer coupled to the motor to receive torque from the motor and impart the striking rotational force to the anvil. The impact tool also includes a locking mechanism operable to selectively lock the drive shaft relative to the housing.
Abstract translation: 冲击工具包括壳体，具有限定第一轴线的输出轴的马达，由壳体围绕基本上垂直于第一轴线定向的第二轴线可旋转地支撑的驱动轴以及联接在马达与驱动轴之间的冲击机构 并且可操作地向驱动轴施加醒目的旋转力。 冲击机构包括由壳体可旋转地支撑并联接到驱动轴的砧座，以及联接到马达的锤，以接收来自马达的扭矩并向砧承受打击旋转力。 冲击工具还包括可操作以相对于壳体选择性地锁定驱动轴的锁定机构。

Abstract: A power tool includes a drive mechanism including an electric motor, a housing, and a spindle rotatable about a longitudinal axis in response to the drive mechanism. The power tool further includes a lockout mechanism including a plurality of detents asymmetrically positioned around the longitudinal axis, where each of the detents are movable between a locking position and an unlocking position. The power tool also includes a collar rotatably coupled to the housing, the collar including a plurality of recesses asymmetrically positioned around the longitudinal axis, wherein in the unlocking position, each of the detents is received in one of the recesses and the spindle is axially movable within the housing, and wherein in the locking position, at least one of the detents is not received in one of the recesses and axial movement of the spindle is prevented by the lockout mechanism.

Abstract: An impact tool includes a housing, a motor having an output shaft defining a first axis, a drive shaft rotatably supported by the housing about a second axis oriented substantially normal to the first axis, and an impact mechanism coupled between the motor and the drive shaft and operable to impart a striking rotational force to the drive shaft. The impact mechanism includes an anvil rotatably supported by the housing and coupled to the drive shaft and a hammer coupled to the motor to receive torque from the motor and impart the striking rotational force to the anvil. A ratcheting mechanism prevents rotation of the drive shaft in a selected direction relative to the housing and includes first and second pawls movably coupled to one of the drive shaft and the housing, and ratchet teeth defined on the other of the drive shaft and the housing.

Abstract: An impact tool includes a housing having a handle portion defining a first axis, a motor supported by the housing, and a rotary impact mechanism arranged on the first axis and configured to receive torque from the motor, the rotary impact mechanism configured to convert a continuous rotational input from the motor to consecutive rotational impacts upon a workpiece. The rotary impact mechanism includes a chamber containing a hydraulic fluid, an anvil positioned at least partially within the chamber, and a hammer for imparting the consecutive rotational impacts upon the anvil, the hydraulic fluid configured to attenuate a noise of the rotary impact mechanism that is created by the hammer impacting the anvil. An output member for receiving torque from the rotary impact mechanism is arranged on a second axis that is perpendicular to the first axis.
