Abstract
A retaining device for attachment to a screw contains a hollow base element for receiving a clamping part. The hollow base element has a floor having a hole, and an inner surface of the base element on the floor area of the retaining device is implemented as conical to contact the outer surface of the conical body of the clamping part. The clamping part can be moved downward in the direction of the floor by rotating the retaining device around its own axis and biting into a screw which is inserted through the hole and runs through the opening of the clamping part.
Claims18
A clamping part comprising a conical body having a longitudinal direction, a center through which an opening runs in the longitudinal direction of the body, and a side wall having at least one slot which runs substantially perpendicular to the longitudinal axis of the clamping part, and an insert received within the at least one slot which projects far enough into the opening that the insert is adapted as a counterpart to a thread of a screw running through the opening;
- wherein the insert has the form of a circular ring sector.
A holder device for attaching a screw, the holder device comprising a hollow base element for receiving a clamping part comprising a conical body having a longitudinal direction, a center through which an opening runs in the longitudinal direction of the body, and a side wall having at least one slot which runs substantially perpendicular to the longitudinal axis of the clamping part, and an insert received within the at least one slot which projects far enough into the opening that the insert is adapted as a counterpart to a thread of a screw running through the opening,
- wherein the hollow base element has a floor having a hole and an inner surface of the base element is implemented as conical to contact an outer surface of the conical body of the clamping part, the clamping part being moved downward in a direction of the floor by rotating the holder device around an axis of the holder device and biting into a screw which is inserted through the hole and runs through the opening of the clamping part.
A clamping part comprising a conical body having a longitudinal direction, a center through which an opening runs in the longitudinal direction of the body, and a side wall having at least one slot which runs substantially perpendicular to the longitudinal axis of the clamping part, and an insert received within the at least one slot which projects far enough into the opening that the insert is adapted as a counterpart to a thread of a screw running through the opening;
- wherein the at least one slot includes three slots at a distance from one another around the circumference of the body, lying in one plane, for receiving one insert each.
A clamping part comprising a conical body having a longitudinal direction, a center through which an opening runs in the longitudinal direction of the body, and a side wall having at least one slot which runs substantially perpendicular to the longitudinal axis of the clamping part, and an insert received within the at least one slot which projects far enough into the opening that the insert is adapted as a counterpart to a thread of a screw running through the opening;
- wherein the conical body has a gap running in the side wall in the longitudinal direction of the clamping part, via which the opening is connected to the environment of the clamping part.
