A ratchet wrench includes two arms extending from one end of the handle, and a head is pivotably connected between the two arms. The head includes a first connection portion and a second connection portion respectively formed to two opposite sides of the head so as to be connected with a pivotable member such as a socket or a bit as needed. The head is pivotable relative to the two arms, and the pivotable member is pivotable relative to the head. The ratchet wrench is able to be used in different angles and positions.

A wrench structure includes a first wrench body, a second wrench body, and a pivot member. The first wrench body is provided with a first mounting portion which is a hexagonal through hole. The first wrench body has a first end provided with a first pivot portion, and a second end provided with a second mounting portion which is a square head. The first pivot portion is provided with a first pivot hole. The second wrench body is provided with a second pivot portion which is pivotally connected with the first pivot portion of the first wrench body. The second pivot portion is provided with a second pivot hole. The pivot member extends through the second pivot hole and the first pivot hole, such that the second wrench body is pivotally connected with the first wrench body.

The invention aims to provide a rotation tool enabling work without obstructing a view of an operator and facilitating fine-adjustment for the tool. A rotation tool includes a flexible shaft including a tool portion at one end and a grip portion at the other end; and a cylindrical exterior body including curved portion on at least a part thereof, wherein a spiral protrusion is formed on at least a part of the shaft and a spiral groove is formed on at least a part of the curved portion, and the shaft is configured to be movable inside the exterior body by screwing the spiral protrusion and the spiral groove to each other.

A fastener driving tool is provided for driving a fastener onto a threaded rod. The fastener driving tool includes a housing, and an input shaft rotatably supported by the housing. The input shaft defines a first rotational axis. An output member is rotatably supported by the housing. The output member is configured to rotatably support the fastener. The output member is configured to receive the fastener and a portion of the threaded rod. A transmission assembly is operatively coupled between the input shaft and the output member. The transmission assembly is configured to convert an input torque from the input shaft about the first rotational axis to an output torque about a second rotational axis acting on the output member. The second rotational axis is disposed at an angle relative to the first rotational axis.

A quick-release structure includes a shaft and a driving assembly. Two ends of the shaft have a receiving hole and a connecting hole, respectively. The driving assembly includes a rotating handle and a connecting rod. One end of the rotating handle is provided with an end cap. The connecting rod includes a pivoting end and a driving section. The rotating handle is pivotally connected to the pivoting end of the connecting rod so that the rotating handle can be pivoted relative to one side of the connecting rod. When in use, the driving section is engaged in the connecting hole, and the rotating handle can be turned to drive the shaft to rotate; when not in use, the driving assembly is inserted into the receiving hole, and the end cap is pressed against an outer end of the receiving hole to be positioned.

A tool adapter includes a body, which is elongated along a first axis. The body includes at least a first side surface that is opposite to the second side surface, as well as a first end surface that is opposite to the second end surface. The body includes a first input drive connector, which is located at a middle section of the body and which is accessible from the first side surface. The first input drive connector is structured to mate with a first drive part of a torque wrench such that a longitudinal axis of the torque wrench is parallel to the first axis when the torque wrench is connected to the adapter. The body includes a first output drive connector that is located at a middle region of the first end surface. The first output drive connector is structured to mate with a first connector part of a tool head such that a longitudinal axis of the tool head is parallel to the first axis when the tool head is connected to the adapter. The first input drive connector is defined to be a first size. The first output drive connector is defined to be a second size, which is different from the second size.

Fittings that generally include a unitary body having an outer surface and an inner lumen forming a void within said unitary body. The lumen is configured to receive threads for mating with the threads of a female sub end of a pipe or tube. The outer surface includes at least one aperture for receiving a tool that can be inserted within said aperture so as to rotate the fitting about an axis that extends through the lumen of the unitary body. The at least one apertures provide a safe and convenient way to tighten and loosen the fitting during the process of coupling pipe or tubing.

This application discloses an apparatus 100 for use with an electrically, hydraulically and/or pneumatically driven torque tool for tightening or loosening inaccessible threaded fasteners including a drive extension assembly 110, a reaction assembly 120 and a socket assembly 130. Advantageously the present invention uses an external reaction member which holds on to two (2) or four (4) adjacent studs while turning a fastener with an extended drive ball and socket joint connection. It more efficiently distributes/reduces the side loads and system strains from the reaction forces on the bolts by bringing the reaction point much closer to the fastener being turned. It allows for a plurality of fastener approach angles and is adaptable to a plurality of fastener obstructions. It's relatively lightweight, easy to maneuver from fastener to fastener and overall user friendly.

A power wrench includes a cylindrical housing, a motor, and an angle head attached to the housing and supporting an output shaft in a laterally extending position. The angle head is connected to the housing via a swivel coupling to enable rotation of the angle head and adjustment of the angular position of the output shaft relative to the housing. A releasable locking device is included between the angle head and the housing for arresting the angle head in alternative angular positions relative to the housing.
