A hand tool for driving a fastener is provided. The hand tool includes gearing that interconnects a splined socket to a rotatable or trigger actuator and increases a rotational speed of the splined socket relative to the actuator. The hand tool may include a power tool receiver 38 or an independent motor to drive rotation of the splined socket to advance or retract a fastener from a threaded shaft. By increasing the speed and conserving rotational inertia, the hand tool reduces the time to secure a fastener on a threaded shaft. A rotatable nut is provided. The rotatable nut can slideably orient along a first axis and threadedly orient along a second axis to fasten to an adjacent surface.

A power tool includes a housing defining a grip portion, a motor having a motor drive shaft, a drive assembly coupled to the motor drive shaft and driven by the motor, an output assembly coupled to the drive assembly and having an output member that receives torque from the drive assembly, causing the output member to rotate about an axis, and a transducer assembly disposed between the grip portion and the output assembly to measure the amount of torque applied through the output member, when the motor is deactivated, in response to the power tool being manually rotated about the axis.

A ratchet wrench with electric assistance includes a wrench body, a ratchet device, a pawl device, and a switch device. The switch device is configured for optionally gearing the pawl device with the ratchet device, so that the ratchet wrench is operated in a clockwise or counterclockwise direction. During the directional changing process, the switch device optionally engages the first gear and the second gear with the transmission gear of the power device, such that the power device transmits the power to the ratchet device for controlling the clockwise or counterclockwise rotation of the ratchet device, realizing the ratchet wrench with an electric assistance function.

An air ratchet wrench has a body, a tool, and a restrictor. The body has two panels disposed at a spaced interval. Each panel has a through hole coaxially aligned with the through hole of the other panel. A first surface is located on a backside of one of the two panels away from the other panel, and a second surface is located on a backside of the other panel. The tool is assembled from the first surface, having a first end and a second end. The first end has an outer diameter larger than an inner diameter of the through hole of the panel that has the first surface. The second end passes through the two through holes, and protrudes on the second surface. The restrictor is sheathed on the tool and constrains the two panels from parting with the first end.

An illumination source disposed in a housing of a tool without the need for fasteners or snaps. The illumination source includes a number illumination elements, such as LEDs, disposed on a circuit board. A lens and the housing cooperatively direct light emitted by the illumination elements away from a user's eyes during use of the tool.

The invention provides, in another aspect, an impact tool comprising 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, a gear coupled for co-rotation with the drive shaft, 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 including, an anvil rotatably supported by the housing and coupled to the drive shaft, the anvil including a pinion engaged with the drive shaft gear, a hammer coupled to the motor to receive torque from the motor and impart the striking rotational force to the anvil, and a spring washer exerting a preload force on the pinion to maintain the pinion meshed with the drive shaft gear.

A powered ratchet tool includes a housing with a battery receptacle, a motor within the housing with an output spindle driven about a first axis, a battery configured to be coupled to the battery receptacle to power the motor, a head pivotably coupled to the housing and configured to pivot with respect to the housing about a second axis perpendicular to the first axis and between a plurality of discrete orientations, the head including a ratchet mechanism driven by the output spindle and an output drive coupled to the ratchet mechanism and configured to rotate about an output drive axis, and a locking mechanism moveable between a first position, in which the head is locked in one of the plurality of discrete orientations with respect to the housing, and a second position, in which the head freely pivots between the plurality of discrete orientations about the second axis.

A torque wrench for use in driving fasteners is provided. The wrench includes an electronics unit disposed within a housing engaged with the body of the wrench that is capable of sensing and measuring the torque applied to a fastener by the wrench and providing an output of the level of torque to the user. The data sensed by the electronics unit can be utilized to provide feedback to the user regarding the operation of the wrench, and to monitor the overall operation of the wrench for calibration purposes, among other functions. During use, the wrench can provide the user with visual, audible and tactile feedback regarding the operation of the device relative to stored maximum torque values stored in the electronics unit. The housing for the electronics unit can be formed to be a single use component of the tool or can be designed for multiple uses with a configuration that can be engaged with cradles forming the body of the wrench having various different configurations.
