  • Patent number: 8418519
    Abstract: The invention relates to a hand tool comprising handles and jaws, where the jaws are operated by the handles, and where an anti-slip device is arranged on the outer side of the distal end of a tool handle. The tool handle has a hard surface with low friction enabling the users fingers to slide on the surface of the handle when squeezing the handles together, and the anti-slip device is arranged to be supported against a support surface in order for the user to be able to press the tool handles together in a controlled manner using a force (F) in excess of hand force.

  • Patent number: 7997116
    Abstract: The invention relates to a link for a crimping tool (2) comprising at least two crimping dies (12,14,16,18) and two tool handles (6,8), where the movable link (23) is arranged between the tool handles (6,8), the link (23) having an opening (72) arranged to engage a guide element (70) on a first handle (6) and being pivotally fixed to a second handle (8), where the guide element (70) is arranged to move from engagement with a first edge (71) of the opening (72) into engagement with a second opposite edge (73) of the opening (72) when the handles (6,8) are brought together to a position where the workpiece (19) is engaged by the crimping dies (12,14,16,18), the link (23) thus enabling the person using the crimping tool (2) to utilize the optimum gripping range of the hand that is about to exert a large force on the handles (6,8) in order to bring them further together for the crimping of the workpiece (19), this regardless of the dimension of the workpiece (19) to be crimped.

  • Patent number: 7334448
    Abstract: A crimp tool and a method of assembling the crimp tool. The crimp tool is formed by a pair of handle plates forming a moveable handle and a pair of frame plates forming a fixed jaw and a fixed handle. The tool also includes a moveable jaw, and a transmission by which the moveable jaw is driven towards and away from the fixed jaw. The handle and frame plates respectively are mutually held in juxtaposition by having edge portions snugly received in handle and frame shells. The tool is assembled by stacking the plates of the moveable handle and the components of the moveable jaw and the link, as well as the frame plates, and then inserting the stack into the frame shell, which preferably has a tubular portion into which the jaw portion of the stack is inserted.

  • Patent number: 7003883
    Abstract: A cable-stripping tool includes two parts that can be moved linearly in relation to each other, each of the parts including an opening which can accommodate a cable when the openings are in mutual alignment. The first part carries a cutting blade and has a support arrangement with a ring that, when rotated about an axis, adjusts a cutting depth of the blade. A spring element functions to bias the parts in a direction away from each other, while enabling the two tool parts to be brought together against the spring bias by a user squeezing with only one hand so that the cable to be stripped can be inserted into the tool intermediate the two ends to which force is applied.

  • Patent number: 6910275
    Abstract: A cable-stripping tool having a body with first and second openings in an upper wall thereof, a central pin mounted in the body with an upper end thereof carrying a cutting blade and projecting through the first opening, and a hook having a concave side which faces toward the cutting blade to receive a cable to be stripped protecting through the second opening. A carrier element is supported on the central pin and axially movable relative thereto, the carrier element being provided with a latching device to which the free end of the stem portion of the hook is coupled such that the hook is axially movable with the carrier element. The latching device coacts with the stem to secure the hook to the carrier element during use of the tool and is actuatable from outside the tool without dismantling the tool such that the stem can be released from the latching device using an instrument and the hook withdrawn for replacement thereof with another hook.

  • Patent number: 6910401
    Abstract: Cable-stripping pliers having between its clamping jaws a cutting unit with mutually co-acting arms including cutting elements. The cutting unit has an abutment body which is movable in the longitudinal direction of the pliers and which limits the stripping length. The body Includes a latching device for latching the arms together in their closed state. The latching device includes a latching finger that engages a recess in the other arm when the abutment body is displaced to one end and the arms are brought together. The Cable-stripping pliers is arranged so that the cutting unit is removed easily when the clamping jaws are open and the cutting unit is in its closed state.

  • Patent number: 6802125
    Abstract: A cable-stripping tool having two parts which can rotate relative to one another about an axis and of which a first part carries a cutting blade in the vicinity of said axis and a second part of which carries a hook which can move axially and which is biased towards an end position relative to the cutting blade by means of a first spring element. A cam disc is non-rotatably connected to the first part and can be moved axially therealong. The cam disc has around its periphery mutually spaced engagement formations which are intended to co-act with a cam follower carried by the second part. A second spring element is adapted to bias the cam disc axially into contact with the cam follower. A third spring element is adapted to rotationally bias the second part relative to the first part.

  • Patent number: 4130031
    Abstract: A wire stripper for removing the insulation from single-core or coaxial cable has a pair of elongated jaws which are hinged together at one end and are provided with a latch at the other end so that they can clamp the wire between them. One of the jaws carries a blade, preferably in a replaceable cartridge, adapted to penetrate into part of the periphery of the insulation of the wire while the other jaw is formed with a bed to receive the wire and hold it during penetration by the blade. One of the jaws is also provided with a ring or eye into which the user can insert a finger and thereby twirl the tool around to effect relative rotation of the tool and the wire to cut through the insulation over its entire circumference. The tool is then drawn off the wire axially or the wire is withdrawn axially from the tool to strip the severed length of insulation from the wire. When two axially spaced cuts are to be made, the replaceable cartridge is formed with two blades in parallel transversely spaced relation.
