The device has a tool body (22) and a holding component (20) for holding the split pin (4) during a bending procedure. The holding component (20) is mounted so as to be rotatable on the tool body (22). The device (18) has a bending element (26) that is disposed on the tool body (22) such that an end of a split pin (4) that is held on the holding component (20) is capable of being bent back by a relative rotation on the bending element (26), in particular in a manner so as to be flush with the shape of the workpiece (2), between the holding component (20) and the tool body (22). ## Claims ### Claim 1 A device for bending a split pin for securing a position of a workpiece said device comprising: a tool body; a holding component for holding the split pin during a bending procedure, wherein the holding component is mounted so as to be rotatable on the tool body; and a bending element which is disposed on the tool body such that an end of a split pin that is held on the holding component is capable of being bent back by a relative rotation on the bending element between the holding component and the tool body; and a mechanism for converting a pivoting movement between two handle parts of the tool body to a translatory movement of the holding component. ### Claim 2 (depends on 1) The device according to claim 1, wherein: a first split pin end of the split pin is capable of being bent back by a relative rotation on the bending element between the tool body and the holding component in a first rotation direction; and a second split pin end of the split pin is capable of being bent back by a relative rotation on the bending element between the tool body and the holding component in a second rotation direction which is counter to the first rotation direction. ### Claim 3 (depends on 1) The device according to either of claim 1, wherein: the holding component holds the split pin on a split pin head of the split pin; and/or the holding component has a mount for holding a split pin head of the split pin. ### Claim 4 (depends on 3) The device according to claim 3, wherein the mount is disposed on a side of the holding component that faces away from the bending element. ### Claim 5 (depends on 1) The device according to claim 1, wherein the holding component during the relative rotation between the holding component and the tool body is securable in a rotationally fixed manner on the workpiece. ### Claim 6 (depends on 1) The device according to claim 1, wherein: the holding component is configured to mesh with the workpiece in order for the holding component to be secured in a rotationally fixed manner on the workpiece, and/or the holding component has at least one fastening element for securing the holding component in a rotationally fixed manner on the workpiece. ### Claim 7 (depends on 6) The device according to claim 6, wherein the at least one fastening element is configured for engaging in at least one clearance in a castellated portion of the workpiece that is configured as a castellated nut. ### Claim 8 (depends on 1) The device according to claim 1, wherein the holding component is configured as a turntable. ### Claim 9 (depends on 8) The device according to claim 8, wherein: the turntable comprises an external wall region disposed on a side of the holding component that faces away from the bending element; and/or the turntable comprises an external wall region configured for partially encompassing the workpiece. ### Claim 10 (depends on 8) The device according to claim 8, wherein the turntable comprises an external wall region that has a clearance space for passing through the split pin. ### Claim 11 (depends on 10) The device according to claim 10, wherein the clearance space is disposed on a side of the holding component that faces away from the bending element. ### Claim 12 (depends on 1) The device according to claim 1, wherein: the holding component is mounted so as to be displaceable on the tool body; and/or the tool body has a slot in which the holding component is displaceably mounted. ### Claim 13 (depends on 1) The device according to claim 1, wherein the mechanism is configured for converting the pivoting movement between two handle parts of the tool body to the translatory movement of the holding component in a direction toward or away from the bending element. ### Claim 14 (depends on 1) The device according to claim 1, wherein the holding component is connected to a thrust bar for displacing the holding component. ### Claim 15 (depends on 14) The device according to claim 14, wherein: the tool body has a first handle part and a second handle part which is pivotably connected to the first handle part; and pivoting of the second handle part in relation to the first handle part causes a displacement of the holding component in relation to the bending element by means of the thrust bar. ### Claim 16 (depends on 1) The device according to claim 1, wherein the bending element comprises a pin. ### Claim 17 (depends on 1) The device according to claim 1, wherein: the workpiece is a nut; or the workpiece is a castellated nut. ### Claim 18 (depends on 1) The device according to claim 1, wherein: the bending element which is disposed on the tool body such that the end of the split pin that is held on the holding component is capable of being bent back by the relative rotation on the bending element in a manner such that the pin is flushed with the shape of the workpiece. ### Claim 19 (depends on 8) The device according to claim 8, wherein: the turntable having an external wall region which is configured as a ring segment portion; or the turntable having an external wall region which is configured as a half-ring segment portion. ### Claim 20 (depends on 10) The device according to claim 10, wherein the external wall region has the clearance space for passing through a split pin portion that adjoins a split pin head of the split pin.
