The fastening tool according to claim 1 , wherein the at least two adjustment surfaces are oriented relative to one another in such a way that the at least two adjustment surfaces or an imaginary extension of the at least two adjustment surfaces intersect in a line perpendicular to the conveying direction when the adjustment tool is in the adjustment position.

5 . The fastening tool according to claim 1 , wherein the adjustment tool includes an adjustment pyramid designed as a truncated pyramid, and is delimited by multiple adjustment surfaces, wherein the multiple adjustment surfaces are inclined surfaces.

6 . The fastening tool according to claim 1 , wherein the adjustment tool is arranged pivotably between an adjustment position and a release position, wherein the adjustment tool has at least one adjustment surface, wherein the at least one adjustment surface is a stop surface which, when the adjustment tool is in the adjustment position in which the adjustment tool is engaged with at least one fastening element of the plurality of fastening elements to be displaced to the desired position, is oriented perpendicular to the conveying direction and is oriented in such a way that the adjustment tool strikes against a surface or an edge of the at least one fastening element which is oriented in particular perpendicular to the conveying direction.

7 . The fastening tool according to claim 6 , wherein the adjustment tool has a shape of a pivoting lever and tapers towards a free end in a region of the stop surface, wherein the region of the stop surface is perpendicular to the conveying direction when the adjustment tool is in the adjustment position.

8 . The fastening tool according to claim 1 , wherein the plurality of fastening elements include a base and two legs fastened to the base, wherein longitudinal extension directions of the two legs of each fastening element of the plurality of fastening elements enclose an angle of less than 180 degrees.

9 . The fastening tool according to claim 1 , wherein the fastening tool is set up to process fastening elements with a base and two legs fastened to the base, wherein both the base and the two legs are in each case formed by metal sheets which extend in the conveying direction in the desired position of the fastening elements.

10 . An adjustment tool for a fastening tool for applying fastening elements to a workpiece, the fastening tool comprising an impact tool configured to convey a fastening element along an impact axis from a loading position within the fastening tool to a workpiece, wherein the fastening element is one of a plurality of fastening elements, each fastening element including a base and two legs fastened to the base and being displaceable in the fastening tool in a conveying direction towards the loading position, wherein:

the adjustment tool includes a plurality of adjustment surfaces;

the plurality of adjustment surfaces are inclined surfaces for adjusting the fastening element;

at least two adjustment surfaces of the plurality of adjustment surfaces are lateral inclined surfaces oriented opposite one another in such a way that each of the lateral inclined surfaces comes into contact with a leg of at least one fastening element;

when the adjustment tool is in the adjustment position, the at least two adjustment surfaces are arranged mirror-symmetrically with respect to a symmetry surface in which both the impact axis and the conveying direction run; and

in order to align the fastening elements while the fastening elements move to the loading position, the lateral inclined surfaces are arranged in a way to displace a particular fastening element in at least one direction perpendicular to the conveying direction into a desired position using a wedge effect, when the adjustment tool is moved counter to the conveying direction of the plurality of fastening elements.

11 . A method for conveying fastening elements, the method comprising:

arranging a plurality of fastening elements one behind another within a magazine of a fastening tool in a conveying direction to a loading position, from which a particular fastening element of the plurality of fastening elements is conveyed to a workpiece using an impact tool, wherein the particular fastening element is located directly upstream of the loading position;

exerting a force on the plurality of fastening elements in a direction of the loading position by using a drive element; and

displacing the particular fastening element into a desired position using an adjustment tool, wherein, in order to align the fastening elements while the fastening elements move to the loading position, the adjustment tool moves counter to the conveying direction for adjustment parallel to the conveying direction and the particular fastening element is adjusted perpendicular to the conveying direction using a wedge effect by at least one of two adjustment surfaces of the adjustment tool, wherein the two adjustment surfaces are inclined surfaces, and wherein, when the adjustment tool is in the adjustment position, the two adjustment surfaces are arranged mirror-symmetrically with respect to a symmetry surface in which both an impact axis and the conveying direction run.
