A dual ratcheting tool having multiple ratchet assemblies and handles for rotating adapters, sockets, and other tools is provided. The dual ratcheting tool includes an upper ratchet assembly independently rotationally and mechanically connected to a lower ratchet assembly; a drive member connected to the upper ratchet assembly and the lower ratchet assembly; an upper handle connected to the upper ratchet assembly, the upper handle having an upper directional switch to set a drive direction of the upper ratchet assembly; and a lower handle connected to the lower ratchet assembly, the lower handle having a lower directional switch to set a drive direction of the lower ratchet assembly. The upper and lower handles of the dual ratcheting tool can independently and in combination can drive a socket more quickly and efficiently than ratchets having a single ratchet assembly and handle.

A tool for tightening or loosening different elements unidirectionally, regardless of the direction of rotation of the input shaft (double-ratchet wrench). Includes a tool or tool accessory which can tighten or loosen screws unidirectionally, regardless of the direction of rotation applied at an input shaft (1), thereby reducing the number of movements required for existing tools to tighten or loosen, for example, a screw. The tool includes a casing (13) containing technology of the type used in energy converters, configured to convert movements in different rotational directions, applied at an input shaft (1), into unidirectional rotational movements at an output shaft (2), which is parallel to the input shaft; and is disposed such that a cutting plane can be drawn through the middle of the shafts, leaving the shaft ends (3.1, 3.2, 3.3, 3.4) visible or outside the casing, with the particularity that it is possible to couple to the input shaft at one end (3.1) or the other (3.2), given that, depending on the end of the input shaft used, the elements coupled to the output shaft (2) will rotate in opposite directions and unidirectionally at each end (3.3 and 3.4) thereof, depending whether a screw is being tightened or loosened.

A ratchet tool having a head having a first cavity is adapted to receive a cover plate and a second cavity. An aperture extends between the first cavity and the second cavity. Disposed in the first cavity is a ratchet gear and a pawl. A selector switch disposed in the second cavity and moves the pawl between a first position and a second position. A retaining clip retains the selector switch in the second cavity. The retaining clip extends into the first cavity. The pawl includes a first extended portion and a second extended portion extending from a lower end of the pawl. At least a portion of the retaining clip is disposed between the first extended portion and the second extended portion. The first extended portion and the second extended portion contact the lower surface of the first cavity. An upper end of the pawl contacts the cover plate.

A wrench rotational axis re-positioning apparatus includes a housing, an interior cavity defined in the housing, input and output gear assemblies mounted to the housing and disposed in the interior cavity in a meshing contact with one another and rotatable about respective first and second axes arranged in a right angle configuration with one another, the input and output gear assemblies having respective input and output fittings for connection to respective drive and driven devices, and a ratcheting mechanism mounted to the housing and extending from exterior thereof into the interior cavity such that the ratcheting mechanism is presettable, or manually manipulatable, in either one of first and second orientations relative to the output gear assembly to enable the latter to correspondingly rotate in one or the other opposite direction about the second axis in response to the input gear assembly being rotated in either opposite direction about the first axis.

An electric ratchet wrench includes a body receiving a driving device for driving a fastener. A first transmission device is connected to the driving device. A second transmission device is connected to a power device. A clutch device is mounted between the first and second transmission devices and is normally in a coupling state for driving the fastener. When the clutch device switches to the disengagement state due to a resistance larger than a torque outputted by the power device, the body can be manually driven to overcome the resistance, forcibly driving the fastener through the large-resistance position. The clutch device returns to the coupling state after the fastener passes the large-resistance position.

A reciprocating apparatus for high torque transfer to a fitting, including tightening or loosening, having two coaxially synchronized engageable drive members provided with a sector geared radial flange engageable with an engageable rotatable drive gear, one internally supported split ratchet gear and drive socket maintained in contact with a spring biased ratchet pawl, together simultaneously rotatable in a first driving direction and independently disengageable in a second direction for reciprocative advancement of a ratchet geared socket in driving engagement with a fitting.

A hand tool for fastening a fastener, such as a screw. The hand tool comprises a handle and a rotatable fastening head connected to a first end of the handle, and engaged with a manually driven actuator. The hand tool further comprises a fixed fastening head connected to a second end of the handle, which is configured to apply a configurable fastening torque to the fastener The fixed fastening head is selectively pivotable with respect to the handle about an axis parallel to the center axis of the fixed fastening head.

A power tool includes a motor and an output assembly configured to receive torque from the motor. The output assembly includes an anvil having a cylindrical body portion, an output member configured to engage a socket, and a curvilinear transition portion that tapers between the body portion and the output member. The transition portion defines a radius in a plane containing a rotational axis of the anvil that is greater than 1.5 mm. The output assembly also includes 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 opposite the first direction.
