A flex-head tool includes a first portion pivotally coupled to a second portion. A pivot mechanism is engaged with the first and the second portions. The pivot mechanism is movable between a first position in which the first portion is fixedly positioned with respect to the second portion, and a second position in which the first portion is pivotal with relative to the second portion. The pivot mechanism includes a toothed first engaging portion engagable with teeth of pivot holes of the first and the second portions simultaneously and not simultaneously selectively and a second engaging portion connected with a pivot hole and in surface-to-surface contact.

A combat vehicle rescue tool for operating a combat lock to open a door of a combat vehicle by engaging an exterior mechanical rescue coupler includes a handle having a first end extending in to a first forked arm and a second forked arm. A selectable angle end wrench includes a box wrench which is sized to fit an exterior mechanical rescue coupler of a combat vehicle door. A rectangular stem of the end wrench has at least three angled faces on a rectangular stem end opposite to the box wrench. A detent mechanism engages each of the at least three angle faces and the pair of face surfaces to set a predetermined angle of the selectable angle end wrench with respect to a long axis of the handle. A spare fastener pin can be threadingly stored in the end face of the tapered end of the tool.

A ratchet wrench capable of rotating quickly and driving rotation includes a handle, a rotary head, a positioning mechanism, and a sleeve. The handle includes an arm and a bar body. The bar body includes an accommodating slot; the arm includes a through hole. The rotary head is connected to the arm and includes recess portions. The positioning mechanism includes a positioning element, a resilient body, and a block element. The resilient body receives the positioning element and is received in the through hole, the positioning element is correspondingly disposed in any of the recess portions, and the block element is connected to the positioning element. The sleeve receives the bar body and operably drives the block element to slide in the accommodating slot, so that the positioning element is positioned and selectively engaged with any recess portion.

A locking clutch ratchet wrench (1) is configured such that a clutch ring (500) forms the mid part of aminate like structure. Under torque applying conditions, the compression forces applied to the clutch ring (500) are substantially dissipated around the circumference (507) of the clutch ring. This inwardly directed force clamp against the inherently strong outer surface 405 of the drive element (400). The resultant pseudo laminate structure of the drive element (400), clutch (500) and housing (201, 202) enables the construction of a proportionately stronger ratchet wrench of reduced height or width.

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.

A pinch-off pliers possessing a canted orientation along the length. The pinch-off pliers has a first clamping unit, a second clamping unit, and an axial mechanism. The pinch-off pliers positioned along a first axis and a second axis, where the first axis is not parallel to the second axis. An intersection of the first axis and the second axis along the length of the pinch-off pliers creates a canting angle theta in the pinch-off pliers at the intersection. An intersection of a first plane and a third plane creates a second canting angle omega when having the pinch-off pliers positioned along the first axis and an intersecting fourth axis.

A fabrication method of a holding sleeve is provided. The holding sleeve is adapted to dispose around a body portion of a main body and can rotate relative to the body portion. A blocking member is disposed in at least one through hole of a first sleeve. A second sleeve is movable relative to and disposed around the first sleeve. The blocking member is controllably pressed by the second sleeve to be partially received in an annular groove of the body portion. An elastic member is disposed around and between the first sleeve the first and second sleeves. Before the second sleeve is mounted to the first sleeve, a part of the elastic member corresponds to the blocking member in a radial direction of the first sleeve and can limit the blocking member to locate in the through hole.

A method of determining an actual amount of torque and/or angle applied to a work piece by a tool. In an embodiment, the method includes determining a rotational angle, a tilt of the tool, and a measured torque of the tool. The actual amount of torque or angle applied to the work piece is then determined based on the rotational angle, the tilt, and the measured torque.

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.

A ratcheting wrench with ratchet heads coupled to a handle via a pin. The pin includes two ball detents that couple to the teeth of the spline in and an indent inside an opening of the ratchet head. The wrench can therefore be easily used in low profile applications and quickly adjusted due to the dual ball detent configuration of the pin.
