Abstract

The pliers comprise two identical moldings (10) forming the handle and jaws (14). The exterior of the molding includes a retention groove for a U shaped spring (13) and the interior surface includes raised moldings (11,16) for locating a shaft (12) that acts as a fulcrum. Pads (50) are located at the jaws of the pliers to grip the components. The pads are semi spherical and are located in recesses (40) in the jaws.

Comme l'illustrent les figures 1, 2 et 3, une pince améliorée selon la présente invention se compose de deux parties de préhension manuelle, 10, qui sont dotées, respectivement et de façon opposée, dans leur partie médiane, d'une saillie, 11, destinée à maintenir un arbre, 12. Un ressort en U, 13, est maintenu entre les deux parties de préhension manuelle 10 de telle sorte que le ressort 13 soit retenu par une fente de retenue, 15, des parties de préhension manuelle 10. Ces dernières sont caractérisées en ce qu'elles sont dotées, respectivement et de façon opposée, d'une saillie, 16, et d'un évidement en forme d'arc, 17, pour positionner l'arbre 12. L'arbre 12 est doté d'une fente arrondie, 18, et il est doté, en outre, à ses deux extrémités longitudinales, respectivement, d'une bride 121, qui est retenue par une rainure de retenue, 101, des parties de préhension manuelle 10 de telle sorte que la fente arrondie 18 de l'arbre 12 se trouve face aux parties de tête 14 des parties de préhension manuelle 10. Les parties de tête 14 sont dotées, respectivement et de façon opposée, d'un corps sphérique de retenue, 19, destiné à retenir une plaque de serrage, 20. A l'intérieur des parties de tête 14 est formée une partie concave interne, 40. Une surface de la plaque de serrage 20 forme une surface saillante, 50, épousant la partie concave interne  As illustrated in FIGS. 1, 2 and 3, an improved gripper according to the present invention consists of two manual gripping parts, 10, which are provided, respectively and in opposite manner, in their median part, with a projection, 11, intended to hold a shaft, 12. A U-shaped spring, 13, is held between the two manual gripping parts 10 so that the spring 13 is retained by a retaining slot, 15, of the manual gripping parts 10 The latter are characterized in that they are provided, respectively and in an opposite manner, with a projection, 16, and an arc-shaped recess, 17, for positioning the shaft 12. The shaft 12 is provided with a rounded slot, 18, and it is further provided, at its two longitudinal ends, respectively, with a flange 121, which is retained by a retaining groove, 101, with manual gripping parts 10 of so that the rounded slot 18 of the shaft 12 faces the head parts te 14 of the manual gripping parts 10. The head parts 14 are provided, respectively and in an opposite manner, with a spherical retaining body, 19, intended to retain a clamping plate, 20. Inside the parts of head 14 is formed an internal concave part, 40. A surface of the clamping plate 20 forms a protruding surface, 50, matching the internal concave part

des parties de tête 14.head parts 14.

Comme illustré sur la figure 5, dans la pince améliorée selon la présente invention, la partie concave interne 40 des parties de tête 14 contient, de chaque côté, une nervure, 60, de façon à permettre à la plaque  As illustrated in FIG. 5, in the improved clamp according to the present invention, the internal concave part 40 of the head parts 14 contains, on each side, a rib, 60, so as to allow the plate

de serrage 20 de basculer légèrement.  clamp 20 to tilt slightly.

On va maintenant décrire la manière dont la présente  We will now describe the way in which the present

invention fonctionne pour obtenir les effets escomptés.  invention works to achieve the desired effects.

Comme l'illustrent les figures 3 et 4, le corps sphérique 10 des parties de tête 14 se trouvant à l'intérieur de la partie concave interne 40 retient la plaque de serrage 20 de façon pivotante. De plus, en mettant à profit la surface saillante 50 de la plaque de serrage 20 se trouvant en face de la partie concave interne 40 des parties de tête 14 dotées de la plaque de serrage 20, cette dernière est à même de serrer fermement et de manière fiable l'article en question. Comme l'illustre la figure 5, en mettant à profit la nervure 60 qui est prévue des deux côtés de la partie concave interne 40 des parties de tête 14 dotées de ladite plaque de serrage 20, cette dernière est capable de basculer légèrement, de manière à permettre de serrer l'article de façon sûre,  As illustrated in FIGS. 3 and 4, the spherical body 10 of the head parts 14 located inside the internal concave part 40 retains the clamping plate 20 pivotally. In addition, by taking advantage of the projecting surface 50 of the clamping plate 20 located opposite the internal concave portion 40 of the head portions 14 provided with the clamping plate 20, the latter is able to tighten firmly and reliably the article in question. As illustrated in FIG. 5, by taking advantage of the rib 60 which is provided on both sides of the internal concave part 40 of the head parts 14 provided with said clamping plate 20, the latter is capable of tilting slightly, so to allow the article to be securely clamped,

sans s'écarter de sa position.without deviating from its position.
