A finger ratchet tool includes a body having a top part on the top thereof, and a ratchet device connected to the underside of the body. The top part includes a tapered face in the outer periphery thereof. Two flanges extend radially from the top part. A connection portion extends from the body. A mounting member has a C-shaped collar which has an opening, and a rod is connected between two ends of the opening. A matching face is defined in the inner periphery of the C-shaped collar. Two recesses are defined in the C-shaped collar and each have two ends. The rod is pivotably connected to the connection portion, and the C-shaped collar is mounted to the top part to match the matching face with the tapered face. The flanges are engaged with the recesses.

A ratchet wrench assembly having an adjustable socket positioned above a main ratchet wrench, the adjustable socket being removable thus providing a separate main ratchet wrench sub-assembly.

A pipe wrench is provided with an extendable handle that fits within a cavity of the head. A lever locks the extended length of the extendable handle along a continuous spectrum between a maximum and a minimum extension of the handle. The lever includes cam surfaces. In an unlocked position, the thickness of the lever between the pivot and a friction plate is less than the thickness between the pivot and the friction plate in the locked position. The friction plate is a composite comprising a top lever plate, a midsection, and a concave surface. The lever plate and concave surface include hard, durable materials, and the midsection is a soft elastic material that redistributes frictional forces across the frictional block. The channel-lock prevents inadvertent overextension and/or accidental removal of the extendable handle.

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.

A standard ratchet wrench assembly having a handle socket member adapted to removably receive a ratchet drive extension member therein, such that a user can use the ratchet drive extension member to increase the moment force upon said standard ratchet wrench assembly when in use.

A hand tool is provided, including: a first member; a second member; a shaft, connected with the first member, rotatably inserted to the second member, including positioning slots; and a control member, disposed on the second member, including at least one tooth; wherein the control member can be released by disengagement of the at least one tooth from the positioning slots so that the first and second members are rotatable relative to each other, and the control member can be locked by engagement of the at least one tooth within at least one of the positioning slots so that the first member is non-rotatable relative to the second member; wherein when the at least one tooth is engaged within at least one positioning slot, at least one blocking wall of the tooth is in gapless surface contact with at least one side wall of the slot.

A pipe wrench is provided with an extendable handle that fits within a cavity of the head. A lever locks the extended length of the extendable handle along a continuous spectrum between a maximum and a minimum extension of the handle. The lever includes cam surfaces. In an unlocked position, the thickness of the lever between the pivot and a friction plate is less than the thickness between the pivot and the friction plate in the locked position. The friction plate is a composite comprising a top lever plate, a midsection, and a concave surface. The lever plate and concave surface include hard, durable materials, and the midsection is a soft elastic material that redistributes frictional forces across the frictional block. The channel-lock prevents inadvertent overextension and/or accidental removal of the extendable handle.

A wrench assembly, and methods of making and using such a wrench assembly, whereby the wrench assembly includes a head, an opening disposed within the head, a first pivotal member coupled to the head, a plurality of radial slots inwardly extending into the first pivotal member, and a handle, whereby the head pivotally couples to the handle.

Various wrenches, wrench systems, and methods of the present invention include inner and outer mouths that provide increased strength and utility. The inner mouth may be configured with an open or a closed end to receive removable open or closed end gears and perform ratcheting action when the gear seated in the inner mouth and engaged and a rotational force is applied to the gear via the wrench. The outer mouth may prevent the gear from disengaging from the inner mouth when the inner mouth is installed in the outer mouth and provide structural strength to the inner mouth when force is applied to the gear via the wrench. Various embodiments include a handle and a head, where the head includes a fixed jaw and a movable jaw, or belt, forming a mouth configured to receive removable open or closed end gears and perform ratcheting action when a fitting is engaged by the gear positioned in the mouth and rotational force is applied to the fitting via the gear and the wrench. The present invention may include two or more stackable sockets to vary the effective length of the socket.

A lug wrench apparatus comprising a collet-type assembly whereby the socket clamps to the lug nut in a manner similar to the way a collet clamps a router bit. The clamping mechanism can be provided either by a screw-compression, or an eccentric cam compression. Arbitrarily large amounts of torque can be applied by means of an extension which fits over the arm of a wrench that is clamped to the shaft of the collet.
