An apparatus for removing lug nuts for changing a tire on a vehicle has a bracing structure and at least three arms connected to the bracing structure. A first arm extends upward and a second arm, adapted to operate as a footrest, extends outward and both arms are positioned such that one may stand on the second arm to generate extra torque while grasping the first arm for stability. A third arm is adapted to receive a socket and is oriented along the socket's axis of rotation. All arms are collapsible for storage.

The present invention relates to a three-piece wrench comprising: a wrench body with a working head and a shaft, the working head is located at a front end of the shaft, the shaft has a length; a first extension rod with a length; and a second extension rod with a length; the lengths of the first extension rod and the second extension rod are greater than the length of the shaft; combination of the wrench body, the first extension rod and the second extension rod provides various usage lengths of the wrench, so that different connection types can be used to form required lengths according to requirements.

A multipurpose and universal wrench for tightening and loosening a fastener, such as a lug nut. The wrench or lug nut wrench can be adapted to lug nuts of varied sizes and shapes. The wrench includes four arms arranged in a cross shape, and three arms are functional while the fourth arm has a torque adjusting handle. Sockets can be interchangeably coupled to the three functional arms. Moreover, the arms are telescoping allowing changing the effective length of the arms. The two opposite functional arms can pivot for collapsing the wrench for storage.

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.

The present disclosure provides a tool comprising a centrally placed tool head disposed between first and second handle portions which a user may grip with either hand in order to comfortable apply torque about the central toolhead from either side in a safe manner. The ability to effectively utilize force from both arms without losing balance facilitates a greater application of torque. The tool may be a wrench of any type utilizing a central wrench head of any type, but may also be another type of leverage-based tool such as a screwdriver or hammered tool.

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 clamping plier head is provided, which is used in cooperation with a first fitting and a second fitting. The second fitting is matched with the first fitting, and the clamping plier head includes an upper head, a lower head and an elastic clamping piece. The upper head and the plier head are matched to form an accommodating cavity for accommodating the first fitting and the second fitting, and at least one of the first fitting and the second fitting is detachably clamped on an inner wall of the accommodating cavity. The elastic clamping piece, with its own resilience, fixes the fittings detachably clamped on the inner wall to the inner wall.

An adapter for a bearing race and seal driver tool that allows the tool to be used in hard to reach applications. The adapter connects to a driver and a handle at a non-zero angle, for example a right angle, to allow the adapter to be struck at a face of the adapter rather than the handle to be struck at an end of the handle. A pocket is included at one or more connection points between the adapter and the handle or driver to resist rotational movement of the handle or driver.

A length adjustable connection structure contains: an adjustment assembly, an engagement assembly, and a receiving tube. The receiving tube includes an insertion accommodated, a coupling portion, a groove, a trench, and an elongated slot. The engagement assembly includes a fixing portion, a toothed portion, a fitting portion, a hexagonal hole, and a circular hole. The adjustment assembly includes a connector, a locating orifice, a hexagonal column, and a C-retainer. The hexagonal column of the adjustment assembly is received in the hexagonal hole of the engagement assembly so that the engagement assembly is connected on the hexagonal column, the C-retainer is engaged in the notch of the hexagonal column, and the adjustment assembly and the engagement assembly are accommodated in the receiving tube, hence the toothed portion of the fixing portion is engaged in the groove of the coupling portion, and the fitting portion is fixed in the trench.

A wrench assembly includes first and second wrench members, and a switch, having an engagement member and a proximal extremity, mounted to the first wrench member. The switch moves between engaging and disengaging positions of the engagement member. The proximal extremity is undepressed in the engagement member engaging position, and is depressed in the engagement member disengaging position. The switch moves from the engagement member engaging position to the engagement member disengaging position, when the second wrench member is partially installed into the first wrench member. The switch moves from the engagement member disengaging position to the engagement member engaging position releasably engaging the engagement member to the complemental engagement member disabling the second wrench member from being withdrawn from the first wrench member, when the engagement member registers with the complemental engagement member when the second wrench member is installed into the first wrench member.
