4. Tool as claimed in any of the foregoing claims, wherein the widened part of the swing bolt and/or the nut comprises an at least partly straight part for the purpose of forming a straight contact surface on the pivotable parts.
5. Tool as claimed in any of the claims 1-3, wherein the widened part of the swing bolt and/or the nut comprises an at least partly conical part for the purpose of forming an oblique contact surface on the pivotable parts.
6. Tool as claimed in any of the foregoing claims, wherein the swing bolt comprises a swing bolt head, at least a part of which has a non-cylindrical external shape, which shape fits non-rotatably in the associated opening in the fork of the holder.
7. Tool as claimed in any of the foregoing claims, wherein the pivotable parts comprise an at least partially conical part on their sides directed toward the fork outer ends.
8. Tool as claimed in claim 5, wherein the respective conical parts correspond with each other such that an oblique contact surface is provided between the swing bolt construction and the pivotable parts.
9. Tool as claimed in any of the foregoing claims, comprising locking means for locking the swing bolt construction, wherein the locking means are arranged in the swing bolt construction.
10. Tool as claimed in any of the foregoing claims, comprising locking means for locking the nut of the swing bolt construction, the locking means comprising:
- a protruding part arranged on the outer end of the swing bolt provided with fastening means;

- a first locking ring which can be fastened non-rotatably to the protruding part of the swing bolt, which locking ring is provided with an external toothing;
- a second locking ring which can be fastened non-rotatably to the nut and placed between the nut and the first locking ring, and which is provided with an internal toothing which can engage on the external toothing of the first locking ring.
11. Tool as claimed in claim 10, wherein the toothings are embodied to enable locking of the nut relative to the swing bolt with relatively small angular displacement steps (.DELTA..alpha.) .
12. Tool as claimed in claim 10, wherein the second locking ring is adapted to enable fastening to the nut in a number (X2) of rotation positions.
13. Tool as claimed in claim 12, wherein the number (N) of teeth of the first and second locking ring equals k plus a multiple of said number of rotation positions (X2), with k a whole number and -X2/2 < k < +X2/2.
14. Tool as claimed in claim 13, wherein the number (N) of teeth equals k plus a multiple of X2, wherein k is a whole number and -X2/2 < k < +X2/2.
15. Tool as claimed in any of the claims 12-14, wherein the play (S degrees) in the locking means is greater than or equal to 360/(k*N*X2) degrees.
16. Tool as claimed in any of the claims 10-15, wherein the second locking ring comprises at least one protrusion which protrudes from the nut in the assembled position.
17. Tool as claimed in any of the claims 10-16, wherein the protruding part is formed such that it fits into one or more corresponding internal recesses which are provided in the first locking ring for non-rotatable fastening of the first locking ring to the swing bolt.
18. Tool as claimed in any of the claims 10-17, wherein the nut is provided with a row of recesses into which external projections provided on the second locking ring can engage to enable non-rotatable fastening of the second locking ring to the nut in a predetermined number (X2) of positions.
19. Tool as claimed in claim 18, wherein the projections
20 are provided on the peripheral surface of the second locking ring, and the recesses are provided in the peripheral edge of the nut, wherein the projections protrude outside the nut in the assembled position.

20. Tool as claimed in any of the foregoing claims, wherein cover elements can be placed over the openings in the outer ends of the fork.
21. Tool as claimed in claim 20, wherein the outer ends of the swing bolt are provided with fastening means for fastening the cover elements during use to the respective outer ends of the swing bolt.
22. Tool as claimed in any of the foregoing claims, wherein hydraulic drive means are provided in the holder which are mounted on the pivotable parts to bring about movement of said parts.
23. Tool as claimed in any of the foregoing claims, wherein the tool is a pair of hydraulic shears, the pivoting parts of which are formed by shear blades.
