For this reason, when tightening the screw (namely when screwing the load) rotates the sleeve and thus also attached to the bottom of the socket, resting on the top of the load flange with the rotation of the screw.
  • connection device from the US 5 248 176 A are used instead of a support pin holding sleeve two axially successively connected sleeves, each of which is provided at its axially outer end with a radially projecting annular flange.
  • the support pin is freely movable within these formed by the two holders holder relative to these and not attached to them, which fixes the disadvantages when screwing to the load to be attached, in the above-described known connection device by the solid connection between them Parts occurred.
  • connection device has a total of a relatively complicated structure with a plurality of individual elements.

  • connection devices of the support pin in the through hole of the sleeve is positively held so that he can not perform any axial relative movement to the socket means used in the invention positive locking an axial slipping out of the sleeve already because of the required axial clearance not that no axial relative movement between Carrying bolt and sleeve should be possible. Rather, in the embodiment according to the invention only a complete axial run out of the sleeve is positively prevented, ie the bolt can not be pulled out of the sleeve in its entirety.
  • the shaft portion with increased shaft diameter consists of an external thread whose threads form the radial enlargement, and the sleeve portion with reduced inner diameter of an internal thread corresponding to the thread on the shaft portion enlarged shaft diameter.
  • the support bolt is screwed when mounted in the device first with its shaft portion enlarged shaft diameter forming external thread through the internal thread of the female portion with reduced inner diameter until the external thread has completely passed through the internal thread. Subsequently, the support pin in the through hole of the socket without further rotation can still be moved axially until the head part of the support bolt rests on top of the socket or on an intermediate shim.
  • the inner diameter of the bush is formed in the region outside the bush portion with a reduced inner diameter greater than the outer diameter of the threads on the shank portion of the support bolt with enlarged shank diameter, so that in the mounted state, the shank portion with enlarged shank diameter in the surrounding bushing portion not on the inner wall of the Socket rests, but this (as well as axially) has a predetermined game, which again favors the screwing of the bolt into a load to be screwed.
  • a particularly simple and therefore cost-effective embodiment of the invention is that the external thread, which represents the shaft portion with increased shaft diameter, is formed directly from the thread, which is provided on the load-facing end portion of the support bolt for screwing the load, wherein the diameter of the remaining portion of the shank of the supporting bolt is smaller than the core diameter of this external thread.
  • the external thread of the shaft portion is provided with enlarged shaft diameter, with mounted support pin, in a central region between the thread for screwing the load on the head part of the supporting bolt end facing away from the latter and the female portion with a reduced inner diameter.
  • the internal thread in the bushing portion with reduced inner diameter at least one complete thread, but preferably includes two complete threads.
