Abstract: A locking pliers preferably includes a fixed jaw, a moveable jaw, a fixed handle, a toggle link, a power link and a jaw link. The fixed jaw is retained in one end of the fixed handle and the moveable jaw is pivotally retained in the one end thereof. An adjustment screw is retained in an opposing end of the fixed handle and engages a first end of the toggle link. A first end of the jaw link is pivotally engaged with a second end of the toggle link. A second end of the jaw link is pivotally engaged with the moveable jaw. One end of a moveable handle is pivotally engaged with a middle of the jaw link. One end of the power link is pivotally engaged with the moveable handle and an opposing end is pivotally engaged with the second end of the toggle link.

Abstract: An applicator (1) has handles (2, 4) which on closing together will engage an animal tag with the animal's ear but at which time a control member (28) will engage with a linkage (6) to trip the linkage (6) into a jaw-open position. Once the handles (2, 4) have been released the linkage (6) will again be returned to its normal position primarily under the bias of a spring (25).

Abstract: A one handed quick release locking pliers preferably includes a fixed jaw, a movable jaw, a fixed handle, a toggle link, a power link and a movable handle. The fixed jaw is retained in one end of the fixed. The movable jaw is pivotally retained in the one end of the fixed handle. A toggle link release surface extends from the second end of the toggle link. A toggle link stop projection extends outward from the actuation portion. The toggle link stop projection provides an over-center stop for clamping an object. A power link release projection extends outward from the movable handle, substantially perpendicular to the toggle link stop projection. The power link release projection contacts the power link. Moving a second end of the movable handle away from the fixed handle will cause the power link release projection to push the power link and release a clamped object.

Abstract: The invention relates to a medical grasping and holding instrument with a handle consisting of two handgrips and with a holding portion that consists of at least two jaw members and can be activated by the handle. The jaw members of the holding portion can be locked by means of a spring element both in an end position that releases the holding portion and in an end position that locks the holding portion. In order to create a medical grasping and holding instrument that is of simple construction, can be operated with just one hand, and is easy to clean, it is proposed with this invention that the spring element, configured as a flat spring, for locking the jaw members in their end positions is mounted between the handgrips of the handle so as to connect the two handgrips to one another in such a way that the spring element can be moved by way of a bearing point of a handgrip at the spring element between two end positions that release the spring element.

Abstract: The locking pliers comprises a first handle connected to a first jaw. A second handle and second jaw are pivotably connected to the first handle and first jaw such that movement of the first handle relative to the second handle causes the jaws to open and close. A mechanism is provided to lock the jaws relative to one another and apply a clamping or gripping force on a workpiece positioned between the jaws. A release mechanism is provided to unlock the pliers that is independent of the locking operation.

Abstract: A quick release for a conventional plier-type, toggle-locking hand tool comprises a compound toggle link. The new link is pivotably mounted between the movable handle and the conventional toggle member. Four pivot points rather than the usual three form the "power line" of the tool. Locking the tool involves pushing the two internal pivot points inwardly across the power line. Release involves opening the handles which moves the internal pivot points back across the power line. Depending on the dimensions of the actual hand tool, the mechanical advantage of the novel compound link is between 4 to 16.
