Abstract: A locking device interacting with a drive member and including an inner tube and an outer tube; where the inner tube has a first free end that projects from, and is axially displaceable from, a first end of the outer tube; where there is a locking member on the other end of the inner tube, said locking member providing the means whereby the inner tube and the outer tube can be releasably locked in various axial positions relative to each other; where the locking member includes a tubular locking sleeve that is slotted by at least one axially aligned slot and a wedge that includes wedge surfaces, the wedge surfaces being, when acted upon by a drive member, displaceable along and relative to interacting wedge surfaces of the locking sleeve, such displacement pressing the locking sleeve against the outer tube, the inner tube and the outer tube.

Abstract: A locking device interacting with a drive member and including an inner tube (1) and an outer tube (3); where the inner tube (1) has a first free end that projects from, and is axially displaceable from, a first end of the outer tube; where there is a locking member (4) on the other end of the inner tube (1), said locking member (4) providing the means whereby the inner tube (1) and the outer tube (3) can be releasably locked in various axial positions relative to each other; where the locking member (4) includes a tubular locking sleeve (9) that is slotted by at least one axially aligned slot (13)—said slot including a wedge-shaped cut-out (113) with essentially tangentially aligned wedge surfaces (16)—and a wedge (14) that includes wedge surfaces (15), said wedge surfaces being, when acted upon by a drive member (41) that includes a thread groove (42), displaceable along and relative to interacting wedge surfaces (16) of the locking sleeve (9), such displacement pressing the locking sleeve (9) against the o

Abstract: A pair of tongs is disclosed that includes first and second spaced apart members each having a first end having a jaw-like part and a second end, the second ends of the first and second members being movable toward and away from each other by the use of one hand. A first connecting element with a first straight toothed surface extends from a point on the first member between its first and second ends and a second connecting element having a second straight toothed surface facing the first straight toothed surface extends from a point on the second member between the first and second ends of the second member for releasably engaging the first connecting element. The first toothed surface includes first and second rows of teeth and the second row of teeth is displaced relative to the first row of teeth.

Abstract: A hand tool for lockably applying a squeezing or separating force to a workpiece. The tool comprises two legs (1,2) which can be pivoted relative to one another and which have first ends which are free and form two jaws (3,4) intended for co-action with the workpiece. The arms are connected together at a distance from the aforesaid ends, by means of a spring element (9). The tool is mainly characterized in that the spring element (9) has an effect which corresponds to that of a compressible pressure spring, and the legs (1,2) are rigid and intened to be pivoted relative to one another, in order to bring the jaws into contact with the workpiece (15) without appreciably compressing the spring element. Arranged between the spring element and the jaws is a locking arrangement (10,12,13) which is intended, subsequent to compressing the spring element (9) to a desired extent with the jaws (3,4) in contact with the workpiece (15) to releasably lock the position of a pivot means between the legs.
