摘要： A lopper used to perform lopping, pruning and similar operations includes a lopping head (12) having a spring-biased blade (18) cooperating with a jaw (20), a drive mechanism (16) connected to the lopping head (12) and an elongate housing (14) connected to the drive mechanism (16). The drive mechanism (16) includes a first and a second mating portion (32, 34) selectively rotatable with respect to one another about an axis (36) permitting positioning of the lopping head relative to the elongate housing (14), a first wheel (50) rotatable about the axis (36), a second wheel (52) rotatable about the axis and coupled to the blade (18) by a head line (54), and a driving line arrangement comprising a driving line (66, 68, 74, 82) arranged to rotate the second wheel (52) and the first wheel (50) together when the driving line is drawn and to keep the second wheel (52) stationary when the lopping head (12) is positioned relative to the elongate housing (14).

摘要： A cutting tool, particularly hedge shears, comprising a first elongated handle member (1), a second elongated handle member (2) pivotally connected to the first handle member (1) at a first pivot point (10), a first blade member (5) having a cutting edge and being pivotally connected to the first handle member (1) at a second pivot point (7), a second blade member (6) having a cutting edge and being pivotally connected to the second handle member (2) at a third pivot point (8), the first and the second blade members (5,6) being pivotally connected to each other at a fourth pivot point (9), the blade members (5,6) being turnable relative to the fourth pivot point (9) so that their cutting edges move in a scissor-like manner between an open and a closed position, the first, second, third and fourth pivot points (10,7,8,9) forming a quadrangle in which an angle the vertex of which is formed by the first pivot point (10) is approaching but not reaching 180° when the blade members (5,6) are approaching their closed position, whereby the work done to close the shears creates a force which tends to close the blade members (5,6) and is the bigger the closer the blades are to their closed position.

摘要： A hand tool for cutting, such as a pair of pruners, includes a pair of opposed elongated members, each member comprising a jaw at a front end portion thereof, a handle at a rear end portion thereof, and a midportion where the members cross over each other. A pivotable joint unites the midportions for scissor-like movement of the handles and jaws, and a spring biases the handles and jaws to an open position. According to the invention, one of the handles is rotatable. A transmission mechanism is provided to interconvert the rotation force applied to the rotatable handle into a rectilinear force used to draw the handles together.

摘要： The invention relates to shears comprising a stationary blade (1) and a movable blade (2) which moves during the shearing movement of the shears. An operating mechanism (5) is arranged to affect a point of the pin (6) located at a distance from the movable blade (2). When the shears are being closed, a force is thus generated which also tries to pull the movable blade (2) towards and against the stationary blade (1) and to keep the blades (1, 2) in contact with each other. The operating mechanism (5) is arranged to affect the joint pin (6) through a sleeve-like part (7). The interior of the sleeve comprises two conical sections (8, 9), the narrowest point of the interior of the sleeve determining the point from which the sleeve-like part (7) affects the joint pin (6).

摘要： The invention relates to a shaft of a tool or the like with an adjustable length, the shaft comprising a first shaft section (2) and a second shaft section (10) which are attached to each other by adjusting means and move telescopically with respect to each other when the shaft length is adjusted. In that case, the adjusting means for adjusting the shaft length comprise a sleeve (4) provided in the second shaft section (10) and an at least partly toothed spindle (6) provided in the first shaft section (2), the first end of the spindle being taken through the sleeve (4). The sleeve (4) and the spindle (6) attach the first (2) and the second (10) shaft section adjustably to each other so that the sleeve (4) and the spindle (6) can be turned with respect to each other into a position preventing the adjustment of the shaft length and into a position allowing the adjustment of the shaft length where the spindle (6) can move in the sleeve (4) in the longitudinal direction.
