Abstract: A battery-driven handtool is configured with a holder (4) for housing the current source, this housing being detachably connected to the handgrip (1) of the tool. The holder is journalled for asymmetric rotation (around A) on the free end of the handgrip, so as to enable the outer dimensions of the tool to be minimized, by causing the holder to take at least two mutually opposing positions when the working space is confined, thereby also enabling the center of gravity point (TP) of the tool to be changed.

Abstract: An adjustable wrench has a fixed jaw at its head. A movable jaw is adapted on a slide glidably accommodated in the wrench head, the slide being positionable in optional positions by means of an adjusting screw or other device. The slide has a web in the form of a substantially planar plate running in a slot in the wrench head. A slide rod is in engagement with grooves in the side walls of the slot. The web has an elongate opening and the slide rod constitutes a separate rod, which is inserted in the elongate opening such that it has lateral play.

Abstract: A wire retainer, as well as a box joint nipper provided with such wire retainer, which is made from sheet metal and fittable to a side nipper of the kind consisting of two members crossing each other at a box joint portion, which are pivotably kept together by a hinge means and form the jaws and handles of the nipper. The wire retainer prevents offcuts from dropping when cutting and has an elastically yielding wire retainer tongue projecting out along one jaw of the nipper to retain the offcut between it and the opposite jaw. The wire retainer has an attachment portion from which the wire retainer tongue projects. The attachment portion comprises a plate with a hook on both side edges for removal and fitting to one of the members of the nipper in the region of the hinged portion.

Abstract: A rotatable hand tool, especially a screwdriver or other rotating tool for screws or nuts. The tool is of the kind having cavities in its handle for storing at least one, or usually several tool bits, which can optionally be attached to a holder attached to and turned by the holder. Such bits can, for example, constitute screwdriver tips, hexagonal socket keys and hexagonal sockets. The handle consists of two main parts, of which one is rotatably enclosed in the other and has cavities arranged in the form of recesses in its periphery, these recesses being accessible by turning the enclosed part so that one of its recesses coincides with an opening in the other part. A limited axial movement between both handle parts and between coacting locking means thereon enables these parts to turn respective to each other in an outer axial position, and is locking them against rotation in an inner axial position of the enclosed part.

Abstract: A sliding joint pliers having a fulcrum pin projecting from one of its limbs and displaceably arranged in a slot in the second of its limbs, has an adjusting screw rotatably mounted on a carrying plate disposed between the limbs. The second limb has a rack along one edge for coaction with the adjusting screw so that the fulcrum pin can be set in a desired position in the slot. The carrying plate is non-rotatably positioned on the fulcrum pin and, together with the second limb and fulcrum pin, is pivotable in relation to the first limb.

Abstract: Pliers in which a spring which moves the pliers handles apart is carried in a recess in one handle, and has a free end sliding in a guiding track in the other handle and which free end moves away from the point of the handles when the same are moved together.

Abstract: A piston-cylinder assembly having a circumferential groove around the piston near the end of the piston facing the cylinder chamber, a cuff around the piston at a location more remote from said chamber from the groove, a guide ring mounted in the groove for slideably abutting the cylinder wall, the guide ring having a convex inner configuration and a generally cylindrical outer configuration.
