The present invention relates to an ergonomic plier tool. More specifically, the invention relates to a piston actuated ergonomic plier tool having a 360-degree rotative and exchangeable head. The tool includes a body, lever, head cylinder, piston and jaw assembly. The disclosed tool allows an operator to work in tight spaces with her hand in one plane, while cutting/manipulating an object in an infinite number of planes different from that of her hand.

A pliers tool (01) includes a hosting pliers that attaches to and manipulates a separate, principal use pliers (02) wherein the hosting pliers has as a first receiver and a first retainer as facilitated by a PLBA (50) that is connected to a first frontward ply (24a). The PLBA (50) is configured to receive and retain to a ply assembly of the hosting pliers a handle of the principal use pliers (02).

The invention regards a tool (1) for applying torque to an maneuvered object, such as for example a screw head or nut, including at least a first jaw (4), and at least a second jaw (5) where the first jaw (4) and the second jaw (5) are connected to at least one lever (arm) (2). What is unique with the tool is that at least one of the jaws (4, 5) includes at least one recess (7) with a first contact surface (8) and a second contact surface (9) of which at least one of the contact surfaces (8) and (9) is arch-shaped. A method of using the tool is also disclosed.

A pliers is provided, including a first clamping body and a second clamping body. The first clamping body has two first jaw portions and two first gripping portions, and the two first jaw portions are associated respectively with the two first gripping portions and are capable of being open or closed relative to each other. The second clamping body has a clamping jaw and a second gripping portion, the second clamping body and the first clamping body are pivotally connected to each other at a location between the clamping jaw and the second gripping portion, and the clamping jaw and the two first jaw portions are capable of being open or closed relative to each other.

According to one example, a spark plug gapping tool includes a first side handle, a second side handle, a middle handle, and a pusher that are made of a non-metallic material. The middle handle is positioned in-between the first side handle and the second side handle, and has a stopper surface and an insert slot that can receive a feeler gauge insert. The pusher is rotatably positioned in-between the first side handle and the second side handle, and has a hollow housing that can receive a terminal end of a spark plug. In operation, a distal end of the middle handle and distal ends of the side handles can move closer together, when a proximal end of the middle handle and proximal ends of the side handles are moved closer together by a user's hand, so as to gap the spark plug.

Pliers are provided. Pliers include an upper handle, a lower handle, an upper jaw coupled to the upper handle, and a lower jaw coupled to the lower handle. In general, the upper jaw includes workpiece engagement surface, such a first set of teeth configured to engage a workpiece, and the lower jaw includes a workpiece engagement surface, such as a second set of teeth and a third set of teeth. The lower jaw opposes the upper jaw such that the first set of teeth faces the second set of teeth and the third set of teeth. At least a section of the workpiece engagement surface of the lower jaw is movably coupled to the lower jaw such that it moves relative to the lower as torque is applied to a workpiece, thereby increasing torque applied to the workpiece.

A hose clamp includes a clamp body formed by bending a plate spring into an annular shape while two ends of the plate spring are caused to cross, grip tabs formed to be raised radially outward from both ends of the clamp body, respectively and an expanded-diameter state retainer formed integrally on the clamp body or the tabs and capable of retaining an expanded-diameter state of the clamp body and releasing the clamp body from the expanded-diameter state by relative movement of both tabs in an axial direction of the clamp body with a gripping operation applied to both tabs. The tabs have respective distal ends, one of which has a larger width than the other. The distal ends are bent circumferentially outward into bent portions spaced from each other. The bent portions are insertable into positioning recesses formed in opposite surfaces of a gripping tool, respectively.
