- the male shaft can have a hexagonal cross-section.
- the end of the screwdriver bit opposite the insertion shank forms a driven profile for insertion into a screwing tool insertion opening of a screw.
- DE 10 2007041 574 A1 discloses a screwing tool which has output profiles at its ends pointing away from one another. The output profiles have different sizes.
- DE 19738 079 A1 shows an essentially hexagonal output profile.
- a generic screwing tool is described in GB 2390317A.
- a shank has a polygonal profile and a cavity at its two free ends.
- In each cavity there is an insert with a different polygonal profile.
- the two inserts are acted upon by a spring element in such a way that they can be moved into the cavity.
- the inserts are supported with stops on counter-stops on the shank.
- GB 2329859A describes a screwing tool in which an insert is inserted in a cavity, which is supported with a head on a step of the cavity and which is acted upon by a spring element.
- the object of the invention is to further develop a screwing tool of the generic type in a manner that is advantageous in terms of use.
- the screwing tool has an elongated shank.
- the elongate shaft has a driven profile at one end, and an end face is located in the region of the driven profile.
- An insert which can be displaced in the direction of the axis of the shank of the screwing tool, is inserted in the cavity in a rotationally fixed manner with respect to the shank.
- the insert can be moved against the restoring force of a spring element.
- One end of the insert protrudes from the cavity.
- This end forms a second output profile.
- the second output profile is similar to the first output profile.
- the cross section of the second driven profile has a similar cross section.
- the second output profile differs from the first output profile essentially in that it has a smaller width across flats.
- the first output profile and the second output profile can also be designed differently, for example it is provided that the second output profile has a cross-slot profile or a slot profile or a circumferential wave profile, as described in DE 19738 079 A1.
- the first output profile can also be such a wave profile.
- the spring element extends in a chamber adjoining the cavity. It can be a prestressed compression spring and in particular a reversing compression spring.
- One end of the spring element is supported on an end face of the insert. It is a face that is opposite to the output profile of the insert. It can be provided that the insert can be pushed completely into the cavity against the restoring force of the spring element until an end face of the insert lies in the plane of the end face of the first driven profile.
- the end of the insert opposite the second output profile can form a head that protrudes radially with respect to the axis.
- a characteristic length is assigned to the shaft in the cavity, for example the edge length of the polygonal profile of the second driven profile or the distance between two surfaces of the polygonal profile pointing away from one another, then the head has a larger characteristic length than this characteristic length.
- the radially protruding stop cooperates with a step in the cavity or chambers, which prevents the insert from being pushed out of the cavity by the compression spring.
- the prestressed compression spring can thus hold the insert in a stop-limited position in which the second driven profile protrudes from the cavity.
- a screw can be turned with the second output profile, which has one of these adapted screw tool insertion openings owns.
- a screw having a larger screw tool insertion opening can be turned with the first output profile.
- the screwing tool is inserted into this larger screwing tool insertion opening.
- the front side of the insert protruding from the cavity touches the bottom of the screwing tool insertion opening.
- the insert deviates into the cavity, so that the first driven profile, which is larger than the second, can be inserted into the screwing tool insertion opening.
- the tool After turning the screw, the tool can be pulled out of the screwing tool insertion opening.
- the relaxing pressure spring shifts the insert back into the stop position.
- the shank can have a third output profile at its second end.
- the third output profile like the first output profile, can be made of the same material as the shank.
- the third output profile also has an end face with an opening of a cavity.
- a second insert In this second cavity is a second insert, which can also be displaced against the restoring force of a spring. It can be the same spring that also acts on the insert having the second output profile.
- the third output profile may have a size slightly larger or slightly smaller than the size of the first output profile. However, the size of the third output profile is preferably larger than the size of the second output profile.
- the fourth output profile is different than the second output profile and may be larger or smaller than the second output profile.

- the shaft can have a larger diameter between the two output profiles.
- the shank can have a polygonal cross-section, for example the edge profile have a greater edge length than the polygonal profile of the two driven profiles.
- the screwing tool can be a screwdriver bit. With the profiled shank, the screwdriver bit can be inserted into a drive tool, for example into a polygonal receiving opening of a ratchet or ratchet.
- the shank has a central bore made by broaching or the like, which extends in the direction of the axis of the shank from one end face to the other end face.
- the central bore is open on both sides.
- the two ends of the central bore form the cavities mentioned above, in each of which an insert with different sized output profiles is inserted.
- the insert nested in a first cavity forms the second output profile which is smaller than the third output profile formed by the second insert nested in a second cavity having a cross-sectional area greater than the cross-sectional area of the first cavity.
- the head of the first insert can have a cross section that is larger than the cross section of the second driven profile and roughly corresponds to the cross section of the second cavity, so that the first insert can be inserted through the second cavity into the central bore.
- This has a circumferential groove at its end opposite the driven profile.
- a C-shaped radially inwardly elastically deformable stop element for example a C-shaped spring element.
- the stop element can be deformed to such an extent that the second insert can be pushed into the second cavity.
- the second cavity is followed by the chamber, which has a larger cross section, so that a step is formed.
- the second insert like the first insert, can then be pushed into the cavity assigned to it in the manner described above. until the face of the insert is flush with the face of the face of the shank having the cavity.
- the compression spring can also be designed in such a way that both inserts can be pushed completely into the cavities assigned to them at the same time, so that at the same time the end face of the first output profile meets the end face of the second output profile and the end face of the third output profile meets the end face of the fourth output profile in one level. It can be provided that both inserts each have circumferential grooves in which an elastically deformable stop element, for example a C-shaped spring element, lies.

- Fig. 27 is a plan view of the free end of the shaft 1 of the ninth embodiment
- Fig. 28 shows a section according to the line XXVIII-XXVIII in Fig. 27.
- the screwdriver bit has a shank 1 which has a length of about 25-30 mm.
- a central portion of the shank 1 has a hexagonal cross-sectional profile with corner notches 16 at the polygonal corners of the profile.
- corner recesses 16 With the aid of these corner recesses 16, the shaft can be temporarily fixed in an insertion opening of a drive tool, not shown, in order to be able to rotate with the drive tool.
- the drive tool can be a screwing tool and in particular a ratchet or a ratchet.
- a first end of the shaft 1 forms a first driven profile 2 with a hexagonal cross-section.
- the first driven profile 2 has an end face 3 with an opening of a cavity 4.
- the second end of the shaft 1 forms a third driven profile 12, which is also a hexagonal profile, but with a slightly larger edge length.
- the end face 13 of the third driven profile 12 has an opening in a cavity 14.
- the two cavities 4 , 14 together with a chamber 6 consisting of the chamber sections 7 and 8 , form a central bore which extends along an axis A of the shaft 1 . While the cross-sectional areas of the cavities 4 and 14 are hexagonal, the cross-sections of the chamber sections 7, 8 can be round or also polygonal.
- the chamber 6 forms a chamber section 7 having a first cross section, which merges into the second chamber section 8, forming a step 9, which has a larger cross section.
- a first insert 19 which forms a second driven profile 21 with a section protruding from the cavity 4, which is a hexagonal profile in the exemplary embodiment.
- the insert 19 has a constant hexagonal cross-section from its end face 20 to a head 22 .
- the cross section of the head 22 is larger than the cross section of the cavity 4 so that the head 22 forms radially projecting stop surfaces 23 which are supported on a step 15 at which the chamber section 7 merges into the cavity 4 .
- the insert 19 is thus inserted in the cavity 4 in a stop-limited and non-rotatable manner.
- the cavity 14 has an internal cross section which is slightly larger than the cross section of the head 22 so that the insert 19 can be inserted through the cavity 14.
- a compression spring 10 and in particular a helical compression spring 10 is provided, which is supported with one of its two ends on an end face 24 of the insert 19 .
- a second insert 25, which forms a shank 28 extending the full length of the insert 25, has a hexagonal cross-section throughout its length that is slightly smaller than the hexagonal cross-section of the cavity 14. Its out of the cavity 14 protruding end forms a fourth driven profile 27, which is larger than the second driven profile 21 but smaller than the first driven profile 2.
- the end of the insert 25 that projects into the chamber section 8 has a circumferential groove 30 .
- the circumferential groove 30 has such a depth that a resilient clamping ring 11 can be accommodated in the circumferential groove 30 . If the clamping ring 11 is compressed in the radial direction, the insert 25 can be inserted into the cavity 14 with its end face 29 in front.
- the second end of the spring element 10 is supported on the end face 29 .
- the clamping ring 11 runs over the step 15', it can deviate in the radial direction in order to be supported on a second step 15' in order to prevent the insert 25, which is arranged in a rotationally fixed manner on the shank, from escaping from the cavity 14.
- the compression spring 10 which is compressed during assembly, holds the two inserts 19, 25 in the stop-limited forward position shown in FIG .
- the respective insert 19, 25 can be displaced in the axial direction until its end face 20 or 26 is aligned with the end face 3, 13 of the shank 1 .
- the second driven profile 21 is to be inserted into the screw tool insertion opening 32 of the screw 31 . Since the screwing tool insertion opening 32 corresponds to the size of the first driven profile 2 and the end face 20 of the second driven profile 21 is supported on the bottom 33 of the screwing tool insertion opening 32, the insert 19 is displaced into the cavity 4 when an axial force is applied to the shaft 1, so that the first driven profile 2 can be inserted into the screw tool insertion opening 32 according to FIG. The stop surface 23 of the head 22 has thereby moved away from the step 15 . When the first driven profile 2 is pulled out of the screw tool insertion opening 32, the compression spring 10 presses the insert 19 back into the starting position shown in FIG.
- FIG. 5 shows the use of the second output profile 21 in a screwing tool insertion opening 23 with a cross section which corresponds to the second output profile 21 . If the second driven profile 21 is inserted into the screwing tool insertion opening 32 , the end face 20 will also be supported on the floor 33 . Here, however, the end face 3 of the first driven profile 2 is supported on the end face of the screw head.
- the stop surface 23 can be slightly spaced from the step 15 .
- FIG. 6 shows an application analogous to FIG. 4, in which the screw tool insertion opening of the screw 31 has a cross section which corresponds to the cross section of the third driven profile 12. If the third driven profile 12 is inserted into the screwing tool insertion opening 32 , the end face 26 of the insert 25 is supported on the bottom 33 of the screwing tool insertion opening 32 . The insert 25 migrates into the cavity 14, with the clamping ring 11 being spaced from the step 15.
- Figure 7 shows an application analogous to Figure 5.
- the cross section of the screwing tool insertion opening 32 corresponds here to the cross section of the fourth output profile 27. If the fourth output profile 27 is inserted into the screwing tool insertion opening 32, the end face 13 of the third output profile 12 can open up the face of the screw head of screw 31.
- the shank can be driven in rotation to turn the screw 31 .
- the polygonal surfaces of the inserts 19, 25 lie flat against the polygonal surfaces of the cavities 4, 14, so that the inserts 19, 25 are assigned to the shank 1 in an axially displaceable but non-rotatable manner.
- the screwing tool which is approximately 35 mm long in total, is thus able to drive screws with four screwing tool insertion openings of different sizes.
- FIG. 9 shows a second exemplary embodiment, which essentially differs from the first exemplary embodiment only in that the insert 19 also has a circumferential groove 30 at its end pointing away from the driven profile 21, in which a spring ring is arranged.
- the invention thus also includes such screwdriver bits in which both bits 19, 25 have circumferential grooves 30 with C-shaped spring washers lying in them at their ends opposite the output profiles 21, 27.
- FIG. 11 shows an insert 19 with a polygonal cross-section in a perspective view.
- the driven profile 21 can also be a square cross-section.
- FIG. 12 shows a perspective view of an insert 19 with a circumferential wave profile as the driven profile 21, as is known under the name Torx.
- the driven profile 21 has a Torx profile.
- the end face 20 has an opening 34.
- the figure 14 shows a perspective view of an insert 19 with a driven profile 21 for insertion into a slot of a slotted screw.
- Figures 15 and 16 show a fifth embodiment, in which the driven profiles are 2 and 12 Torx profiles that form different wrench sizes from each other.
