Abstract: The pruning shears have a link pivotally connecting the force-lever arm of the cutter with the tang and a strap bridging the cutter and tang. In this way, the tilting movement, to which the joints are otherwise exposed, is counteracted by the strap.

Abstract: In garden shears of this type, the anvil and/or the cutter are adjustable with respect to the cutting edge of the blade. For this purpose, the anvil has slots which may be linear or curved and are set at an angle with respect to the cutting edge. These slots serve as guidance for anvil bushings which are slidably disposed in the slots. Together with screws which are threaded into the bushings, a clamping connection is produced between the anvil and the shear arm. In the cutting direction there is provided, in every position, a locked support via the anvil bushings in the guide slots.

Abstract: In garden shears the locking device which holds the shear grips in closed position against the force of an opening spring is developed as a slide grip which lies free both on the top and on the bottom of the one hand grip so that this slide can be actuated by the thumb of both the right hand and the left hand without it being necessary also to use the other hand. The slide grip has spring detents which cooperate with indentations in said one hand grip.

Abstract: A garden shears is provided with replaceable knives mounted on elongated grips which are connected at a pivot joint that is constructed of a steel bushing that takes up radial loads (shear and flexure). Axial loads are taken up by a screw bushing which passes through the steel bushing and a joint screw threadably engaged with the screw bushing. Both the joint screw and the screw bushing have widened shallow heads with slightly convex surfaces that pass into surfaces of the shears. The replaceable knives are supported at the rear by extensions of the respective grips in a manner such that the knives are not required to take up bending moments.

Abstract: A cutting blade (16) of rose-gripping shears cooperates with an anvil (30). A clamping piece (50), which has a clamping plate (52) which rests against the anvil (30) in the closed position, is movable together with the cutting blade (16). The said clamping piece can move backwards under spring action in order to hold a cut stem between the clamping plate (52) and the anvil (30). The spring urging of the clamping piece (50) is obtained by a spring arm (56) which extends in an arcuate section around the swivel pin (22) between the shear arms and comes against a mounting plate (58) which is connected, fixed for rotation, to the gripping lever of the cutting blade (16).

Abstract: The swivel joint of the shears comprises a dish-like rotary head 14 which is moulded from plastic and which is inserted with an inner bush 46 into a swivel joint bush 44 of an extension provided with the fixed upper grip 10. The axial fixing is via a detent means 54, 56.On the rotary head 40 the lower blade 50 is fixedly disposed and the upper blade 68 is pivotal on a bearing bush 58 of the rotary head. A pull rod 78 led through the bush 46 is anchored with a bent end to the movable upper blade laterally of the pivot axis thereof. The other end is anchored in an adjustment bush 82 which is adjustably fixed in an adjustment pin 84. The locking is by a plastic slide 24 which is disposed at the front end of the upper grip and can easily be displaced with the thumb to lock or unlock the lower grip or movable blade.

Abstract: In a cutting head for an electric-motor-driven filament-type cutter the automatic adjustment of the length of the filament is effected in that intermittently a rotational movement occurs between a filament spool (36) and a sleeve (24) mounting said spool for axial displacement. The sleeve (24) is provided on the outside with locking cams and the filament spool on the inside with cams cooperating therewith. The sleeve (24) can be pushed in by hand against spring pressure to cancel the intermittent locking. For automatic filament adjustment a centrifugal adjustment is provided. For this purpose at least two radial ball slots (40) are provided between the housing portion (14) and a radial extension (48) of the sleeve (24) and in the ball slots balls (44) are guided which are adapted to be urged outwardly by centrifugal force.
