Abstract
Single-handedly operable, self-closing pincers (1) having two pincer limbs (2, 3) which are interconnected by means of a joint pin (4), a pincer mouth (M) being formed above the crossing region of the pincer limbs (2, 3) and grip sections (7, 8) being provided on the pincer limbs (2, 3) below the crossing region, one (3) of the pincer limbs, which can be adjusted in the crossing region relative to the other pincer limb (2) in order to vary the size of the pincer mouth (M), having a free space (F), which is penetrated by the other pincer limb (2), or the non-adjustable pincer limb being penetrated by the adjustable pincer limb, and, furthermore, the pincer limbs (2, 3) being connected via a control member (13) and a spring drive having a spring (14) which biases the pincer mouth (M) into an open position, which open position is produced automatically by the spring loading after unloading of the grip sections (7, 8), wherein, in addition, the pincer mouth jaws (5, 6) move towards one another in a first movement section of the spring drive (12), and a pawl (10) of the joint pin (4) engages in a latching tooth system (11) in a second movement section, whereafter a forced rotation of the movable pincer mouth jaw (6) about the joint pin (4) can be carried out, characterized in that the spring drive comprises a spring (14) which is supported on both pincer limbs (2, 3) and is arranged such that both spreading of the pincer limbs (2, 3) into a spaced-apart position relative to one another and a movement of the movable pincer limb (3) into the position of the largest mouth opening, with rotation of pincer limb (3), is effected by this spring (14), wherein in any case at one end a rotation support of the spring (14) is provided on the pincer limb (2), and the spring (14) bears at this end in the non-operated state agains a rotation stop provided on the pincer limb (2), and wherein, upon displacement of the movable pincer limb (3) into a mouth closing position gripping a workpiece (object 18), the spring (14) comes clear of the rotational stop only after forced operation, when the pincer mouth jaws (5, 6) engage against the workpiece.
