Definitions

  • the invention relates to a socket wrench for polygonal screws, with a pressure piece which rests by spring force against a lateral drive surface or a polygonal edge of the screw head and which is arranged in a wall opening in the socket wrench, the pressure piece being designed as a ball lying in a wall bore with inner support shoulders and to apply the spring force a lying in an outer, circular peripheral surface of the key lying, slotted, with respect to its circumferential position fixed clamping ring is provided.
  • the known socket wrenches are known, for example, from German utility model G 84 28 029.8 or German utility model 295 19 325.5.
  • socket wrenches are preferably used for holding and turning non-ferromagnetic screws, in which the socket wrenches which are otherwise customary and are equipped with an inner magnet are ineffective with regard to the holding effect of the magnet on the screw head.
  • the invention has for its object to provide a generic socket wrench in such a way that the holding force exerted on the screw head is optimized.
  • the holding force on the screw head can be increased in the case of clamping rings of the same thickness in that the clamping ring slot assumes the claimed geometrical position with respect to the ball.
  • a clamping ring can be used whose thickness is approximately 50% smaller than that of the clamping rings used otherwise, the holding force on the screw head in the claimed angular range for the thinner clamping ring is approximately as large as that for the thicker clamping ring when the slot center of the ball z. B. is exactly opposite.
  • the groove to be milled can also be designed to be comparatively flat on the peripheral surface of the key, so that there is practically no noticeable reduction in the wall thickness of the socket key.
  • the position of the slot is such that the angle between the connecting lines is less than 40 °, there is a risk that one edge of the slot will press outward over the other, so that a projection is again formed, which can lead to injuries to the user.
  • the upper end face or end edge of the clamping ring carries a nose which engages in a recess in the peripheral surface or U fangswandung the key head. Since the width of the clamping ring is only slightly smaller than the groove width, the clamping ring cannot slide out of the recess with its nose.
  • Fig. 1 shows a section through a socket wrench according to the invention
  • Fig. 2 is a side view of the socket wrench acc. Fig. 1.
  • the socket wrench 1 consists of a clamping pin 2 which can be inserted in a rotationally fixed manner into a drill chuck, a quick-change chuck or the like of a tool which can be driven in rotation.
  • a groove 6 is incorporated, in which a slotted clamping ring 7 lies in a rotationally secure manner.
  • the rotationally secure position of the clamping ring 7 is achieved by a lug 8 which is carried by the groove edge 9 in the illustrated embodiment and engages in a correspondingly shaped recess 10 which is formed in the wall 11 of the clamping ring 7.
  • the slot 17 of the clamping ring 7 is arranged according to FIG. 1 with respect to its geometrical circumferential position in such a way that the connecting line 18 of the center of the circumference of the key head with the center of the ball and the connecting line 19 of the center Point of the key head circumference with the slot center of the clamping ring slot 17 includes an angle ⁇ of 60 °.

Abstract

Dans des clés à tube pour têtes de vis polygonales, on utilise, pour maintenir la tête de vis, une bille (16) qui est placée dans un alésage (13) de la paroi de la tête de clé (3) et qui est pressée, de façon élastique, par une bague ressort (7), contre la tête de vis. Pour optimiser la force élastique de la bague ressort (7) fendue, il est proposé de fixer ladite bague ressort (7), en ce qui concerne sa périphérie, de sorte que le centre de sa fente se trouve à un angle compris entre 40 et 90 DEG , ledit angle étant formé par la ligne de liaison (18), reliant le point central de la périphérie de la tête de clé avec le point central de la vis, et par la ligne de liaison (19), reliant le point central de la périphérie de la tête de clé avec le centre de la fente (17) de la bague ressort.
