A ratchet extender includes a first head having at least one ratchet drive square receiver and a first drive gear, a second head having at least one ratchet drive square and a second drive gear, and a drive shaft coupling the first drive gear to the second drive gear. As a user rotates the first drive gear using a ratchet coupled to the ratchet drive square receiver, the drive shaft rotates, thereby rotating the second drive gear and the ratchet drive square coupled thereto. As a result, a user is able to use ratchets in locations previously unreachable by such tools.

A dustproof structure of a hand tool includes a tool body and a dustproof element. The tool body has a shank. A predetermined portion of the shank is concavely provided with a through hole. The dustproof element is flexible, is provided at the through hole of the shank, and can be opened and closed. The dustproof element closes the through hole when not subjected to an applied force and is elastically deformed to render the through hole into an open state when subjected to the applied force. In normal conditions, therefore, the dustproof element can block foreign matter from entering the through hole. When it is desired to perform a lubricating or adjusting operation on a component in the through hole of the hand tool, the operation can be carried out after directly applying a force to, and thus deforming, the dustproof portion, without having the dustproof element removed.

A high-torque ratchet wrench including a wrench body having a driving aperture and a handle, and a drive member is disposed in the driving aperture and an axial position-limiting mechanism is disposed between the driving aperture and the drive member to limit the relative axial displacement. The external side wall of the drive member and the internal aperture side of the driving aperture form two cylindrical drive faces nested, wherein a first cylindrical drive face is provided with a pin recess, a pin is rotatably mounted in the pin recess, a relief is disposed on the side face of pin, the pin is connected with a resilient reset member, the pin is rotated with the resilience of a resilient reset member, and a relief is driven to stand out of the pin recess and contacts a second drive face.

The present invention surrounds to a ratchet apparatus, system and use thereof. The invention is presented to provide additional mechanical advantage and added angular engagement of a ratcheting wrench. In particular the present invention provides increased torque and angular engagement within a compact space without requiring an extended handle, wherein an extended handle reduces portability and further restricts access and movement within confined spaces.

A ratchet wrench allowing easy change of rotation direction includes a main body, a ratchet gear, a pawl, a sideways pushing member, and a direction changing device. The main body has a shaft connected with a head portion. The head portion has a receiving chamber housing the ratchet gear, the pawl, and the sideways pushing member and connected to a channel in the shaft. The direction changing device has a rotating rod in the channel, a sideways pushing button for rotating the rotating rod, an engaging member at the rear end of the sideways pushing member, and an engaging groove at the front end of the rotating rod and engaged with the engaging member, which is axially offset from the rotating rod. The rotating rod can rotate the sideways pushing member and thereby displace the pawl so that a different portion of the pawl meshes with the ratchet gear.

A gearing and crankshaft assembly for a powered hand tool including an integrated gear carrier and crankshaft including first and second opposing ends, where the first end includes an offset pin, gears rotatably coupled to the integrated gear carrier and crankshaft by gear pins, bearings adapted to receive the integrated gear carrier and crank shaft to allow the integrated gear carrier and crank shaft to rotate relative to the driver portion, and a gear cover coupled to the driver portion and adapted to restrict axial movement of the gears.

The present invention provides an extendable wrench comprising: a wrench having a head portion and a shaft connected to a rear end of the head portion; an insertion hole recessed at a rear end of the shaft; a cover to dismountably close the insertion hole; an extension rod with a front end formed with a plug to be plug-connected with or separated from the insertion hole of the wrench; and an elastic positioning member provided between the plug of the extension rod and the insertion hole of the wrench, when the plug of the extension rod is plug-connected with the insertion hole, the elastic positioning member keeps the plug in position. Thereby, the wrench can be operated independently; when application of larger operating torque is required, the extension rod can be combined with a rear end of the wrench to form a longer operating arm of force to meet the requirements of large torque.

A wrench includes a driving unit located in the head of the wrench. A rod extends through the driving member and includes a stepped recess so as to control a bead in the radial hole of the driving member to secure a socket connected to the driving member. A rotary member is connected to the head and includes a room. A locking member is located in the room and locked to the driving member. A fixing area is formed between the locking member and the driving member so as to fix the locking member and the driving member together. The fixing area ensures that locking member is not separated from the driving member.

A hand tool including a control element for receiving one or more finger digits of a user. The control element is positioned on the body component and may be in the form of an aperture defined by a perimeter surface. A user places one or more fingers within the control element and applies pressure to rotate the body component.

A tool kit is provided that includes a tool including a handle and a tool head and a set of tool accessories configured to be coupled to the tool head. The tool accessories each including a drive end that is configured to be coupled to the tool head and a working end opposite the drive end. The tool kit includes a container that is movable between an open position and a closed position. The container includes a first portion including a first retainer that supports the tool, a second portion and a middle portion dividing the first portion from the second portion. The middle portion including a second retainer that supports the tool accessories and the container is selectively stored in a closed position where the middle portion supports the container on a surface in an upright position.
