A light-weight bolt cutter tool includes a pair of opposing pivotally mounted jaws, each made from a fiber-reinforced composite body jacketed by a blade having a hardened metal outer surface oriented to forcibly engage the other one of said jaws. Each jaw can have pair of indentations proving the jaw with an I-beam-type cross-sectional shape. The bolt cutter tool can be actuated by a pair of elongated, hollow fiber resin composite handles. Each handle can include an elastomeric damping plug to prevent debris entering the hollow handle and reduce material fatigue. A quick-deployment, quiver-style backpack can conveniently carry the colt cutters when not in use.

A hand tool with a mechanical linear drive mechanism coupled to a linear activated working implement. The drive mechanism includes a roller screw that includes a torque tube connected to a roller screw's nut body. The roller screw includes a fixed outer race, a rotating set of grooved rollers axially aligned inside the outer race, a cylindrical nut body located inside the set of grooved roller, a plurality of inner rollers axially aligned and inside the nut body, a threaded shaft axially aligned and inside the inner rollers, and a torque tube axially aligned inside the inner rollers. The torque tube is connected at one end to a multiple speed gear box which includes a primary motor coupled to a earner gear with three planet gears. Disposed around the planet gears is a ring gear. Coupled to the ring gear is a secondary motor which when activated causes the ring gear to rotate in the opposite direction of the planet gears. At least one sensor measures the rotation of an elastomeric ring and control activation of the secondary motor to change the operational speed of the tool.

A hand tool includes a first jaw; a first handle coupled to a second jaw, the second jaw pivotably coupled to the first jaw and having a first geared structure, the first geared structure including a first plurality of teeth and a first bearing surface; and, a second handle coupled to a lever, the lever pivotably coupled to the first jaw and including a second geared structure, the second geared structure including a second plurality of teeth and a second bearing surface, wherein the first and second handles are movable between a full open position and a full close position such that during movement from the full open position to the full close position, the first plurality of teeth are at least partially engaged with the second plurality of teeth and the first and second bearing surfaces are in rolling contact.

A hand-held tool that is prepared for remote control has a handle region, an actuating button, and a removable attachment part held in the handle region. The attachment part has a handling extension and a collar encompassing the handle region. The collar includes first and second collar parts pivotably connected together. The attachment part acts upon the actuating button. The actuating button is displaced into an actuating position by a housing section of the collar for a duration of an arrangement of the attachment part on the handle region.

The invention relates to a bolt cutter (1) which can be used for cutting a workpiece, especially a workpiece that is bolt-like. The bolt cutter comprises a fixed hand lever (3) and a movable hand lever (2). A cutting jaw (8) is fixedly connected to the fixed hand lever (3). The movable hand lever (2) via a ratchet gear (7) is coupled to a movable cutting jaw (6).

In an opening position of the cutting jaws (6, 8) the movable cutting jaw (6) lies against a rest (55) supported by a support spring (54). By manual application of an opening force, the movable cutting jaw (6) can be moved into an enlarged opening position from the mentioned opening position by pressurizing the support spring (54). When the manually applied opening force is removed, the movable cutting jaw (6) automatically returns to the opening position from the enlarged opening position due to the support spring (54).

A control device for a piece of powered equipment having an electronic sensor and an electronic control board for controlling the equipment depending on a control signal from the sensor. The electronic sensor is a contactless optical sensor, provided in an interface area of the control device, configured to measure a distance separating at least one target, located in the interface area, and the optical sensor, the electronic board being configured to establish a first control of a main function of the powered equipment, when a signal from the optical sensor is established for a measured distance within a first range of distances, and to establish a control for at least one additional function of the powered equipment, different from the main function, when a signal from the optical sensor is established for a measured distance greater than the first range of distances.

An in-line portable, hand held hydraulic cutting tool having a handle assembly and a working head assembly is provided. The handle assembly has a tool frame portion and a neck portion. The working head assembly has a pair of jaw members joined so that they are movable relative to each other and held in place by a locking pin. Each jaw member has a cutting blade secured to or directly formed into the jaw member. A stabilizer can be secured to or directly formed into one or both jaw members. The one or more stabilizers are aligned with a respective cutting blade such that during a cutting operation at least an edge of the stabilizer engages an object being cut to limit rotation of the object during the cutting operation.

Hand tools which have an ergonomic using a palm handle and finger handle designs which achieve mechanical efficiency and ease of use. The ergonomic handle is compatible with the muscle movements of an operator using a hand tool reducing muscle strain and pain. Optionally, the palm and finger handles can have ergonomically designed cushions. In an embodiment, the finger handle can have a finger set which has a forward finger flange, a tail finger flange and a pinky grip. The ergonomic handle can also use a relief washer system to achieve a smooth low frictional resistance cutting stroke.
