Abstract
The disclosure relates to a screwdriver attachment for screws, which has a first shaft section with a first longitudinal axis, and a second shaft section with a second longitudinal axis. The second shaft section is coupled to the first shaft section via a linking disk. The first shaft section has a free end with which the screws are turned. The first shaft section and second shaft section are connected to one another by a spring element, which aligns the first shaft section in a starting position in which the first longitudinal axis and the second longitudinal axis are aligned coaxially. Screws can be readily turned with the screwdriver attachment according to the disclosure, even if there is a certain offset between the axes.
Claims19
A screwdriver attachment for screws, comprising:
- a first shaft section with a first longitudinal axis, and
- a second shaft section with a second longitudinal axis, which is coupled to the first shaft section via a linking disk,
- wherein the first shaft section has a free end with which the screws are able to be turned,
- wherein the first shaft section and the second shaft section are connected to one another by a spring element, which aligns the first shaft section in a starting position in which the first longitudinal axis and the second longitudinal axis are aligned coaxially, and
- wherein the second shaft section has a back end through which the spring element is inserted.
A screwdriver attachment for screws, comprising:
- a first shaft section with a first longitudinal axis, and
- a second shaft section with a second longitudinal axis, which is coupled to the first shaft section via a linking disk,
- wherein the first shaft section has a free end with which the screws are able to be turned,
- wherein the first shaft section and the second shaft section are connected to one another by a spring element, which aligns the first shaft section in a starting position in which the first longitudinal axis and the second longitudinal axis are aligned coaxially,
- wherein the second shaft section is received in a receiver unit, which has a first fastening ring and a second fastening ring, wherein the first and second fastening rings are spaced apart and located on a clamping sleeve in which the second shaft section is received.
A screwdriver attachment for screws, comprising:
- a first shaft section with a first longitudinal axis, and
- a second shaft section with a second longitudinal axis, which is coupled to the first shaft section via a linking disk,
- wherein the first shaft section has a free end with which the screws can be turned, and
- wherein the first shaft section and the second shaft section are connected to one another by a spring element;
- wherein said spring element has an end which is configured to substantially remain in alignment with said first longitudinal axis of said first shaft section when an offset between said first shaft section and said second shaft section occurs.
A screwdriver attachment for screws, comprising:
- a first shaft section with a first longitudinal axis, and
- a second shaft section with a second longitudinal axis, which is coupled to the first shaft section via a linking disk,
- wherein said linking disk compensates for radial offset between said first shaft section and said second shaft section,
- wherein the first shaft section has a free end with which the screws can be turned,
- wherein said first shaft section applies torque to tighten said screws when said first longitudinal axis of said first shaft section is offset from said second longitudinal axis of said second shaft section;
- wherein said first shaft section and said second shaft section are connected together by a spring element which has an end located in a bore of said first shaft section wherein said bore retains said spring element in substantial alignment with said first longitudinal axis when a radial offset occurs between said first shaft section and said second shaft section.
