Multiple tool

1. A multiple tool, comprising:

a pivot having a first end and a second end;

a plurality of implements, each comprising an opening through which the pivot engages, wherein each of the implements is rotatable about the pivot from an inactive position to an operating position;

a clamping means located at the first end of the pivot comprising a bushing screwed to the first end of the pivot, wherein the bushing comprises a compression surface; and

an elastic retention means comprising:

a compression spring located at the second end of the pivot when engaged by the implements;

a first closing element interposed between an end one of the implements and the compression spring; and

a second closing element interposed between the end one of the implements and the compression surface of the bushing.

2. The multiple tool of claim 1 , further comprising a collar at the second end of the pivot for engaging with the compression spring.

3. The multiple tool of claim 1 , wherein the first closing element comprises a first bushing body having a resting surface for a terminal coil of the compression spring.

4. The multiple tool of claim 1 , wherein the second closing element comprises a second bushing body having a lodging for the bushing on which rests the compression surface.

5. The multiple tool of claim 1 , wherein for each of the implements, the elastic retention means comprises:

an anular body mounted along the pivot;

a first face comprising a bump; and

a second face opposed to the first face and comprising a plurality of recesses.

6. The multiple tool of claim 5 , wherein the bump comprises a sphere engaged in a corresponding seat in the first face.

7. The multiple tool of claim 5 , wherein the first closing element comprises a first base having a bump configured to selectively engage in one of the plurality of recesses of an end implement or having a plurality of recesses configured to be selectively engaged by the bump of an end implement.

8. The multiple tool of claim 7 , wherein the second closing element comprises a second base having a plurality of recesses configured to be selectively engaged by the bump of an end implement or having a bump configured to selectively engage one of the plurality of recesses of an end implement.

9. The multiple tool of claim 5 , wherein the plurality is four and the recesses are spaced 90° apart.

10. The multiple tool of claim 1 , wherein the pivot comprises a tubular portion defining an inner surface in which an internal thread is provided for the screwing of a corresponding external thread in the bushing.

11. The multiple tool of claim 1 , further comprising a handle connected to at least one of the first end and the second end of the pivot.

12. The multiple tool of claim 11 , wherein the handle is connected to the first end and the second end of the pivot.

13. The multiple tool of claim 1 , further comprising a second pivot parallel to the pivot from which at least one of the plurality of implements is rotatable thereon.

14. The multiple tool of claim 13 , wherein the second pivot comprises an elastic retention means.

15. The multiple tool of claim 13 , further comprising connection means for connecting the pivot to the second pivot.

16. The multiple tool of claim 15 , wherein the connection means comprises a first bar that rigidly connects the first closing element of the pivot to a first closing element of the second pivot.

17. The multiple tool of claim 16 , wherein the connection means comprises a second bar that rigidly connects the second closing element of the pivot to a second closing element of the second pivot.

18. The multiple tool of claim 1 , wherein each of the plurality of implements comprises an annular body articulated to the pivot.
