[0022] FIG. 2 illustrates a shaft end of the sheet metal dent repair hook with a coupling element disengaged from the sheet metal dent repair hook exchange handle; and

[0023] FIG. 3 illustrates the handle element coupling in top view (FIG. 3A), in a longitudinal sectional view (FIG. 3B) and in a cross sectional view along the lines A-A (FIG. 3C) through the push-pull interlocking arrangement and in a cross sectional view B-B (FIG. 3D) through the teething.

DETAILED DESCRIPTION OF THE INVENTION

[0024] FIG. 1 illustrates a sheet metal dent repair hook 1 including a shaft 2 including a hook 3 at one end and a coupling element 4 at another end. The sheet metal dent repair hook 1 is inserted with the coupling element 4 into a handle element coupling 5 of the sheet metal dent repair hook exchange handle 6. At the handle element coupling 5 a hand grip 7 is arranged at a right angle to the handle element coupling 5 certainly the sheet metal dent repair hook exchange handle grip 6 can also have a piston shape.

[0025] FIG. 2 illustrates an end of the shaft 2 of the sheet metal dent repair hook 1 of FIG. 1 including the coupling element 4 that is pulled out of the handle element coupling 5. The coupling element 4 includes an outer teething 8 at an end oriented towards the sheet metal dent repair hook exchange handle 6. Furthermore a recess 9 is arranged at a circumference of the coupling element 4 adapted to the handle element coupling 5 in a portion 33 configured to engage interlocking devices 10 that are not illustrated in this drawing figure wherein the interlocking devices are arranged in the handle coupling 5 and subsequently illustrated in FIG. 3 and described in more detail. A push-pull locking ring 11 is arranged on an outside of the handle element coupling 5 and forms an interlocking arrangement 32.

[0026] FIG. 3 illustrates the handle element coupling 5 with the inserted element coupling element 4 in detail in different illustrations. As stated supra the handle element coupling 5 includes a push-pull locking ring 11 of a locking device 32 wherein the locking ring is circumferentially arranged and mounted axially movable on an outside of a coupling housing 12 wherein the axial movement is performed against a force of a spring 13 in the axial direction. An arresting arrangement 14 is arranged at an end of the coupling housing 12 that is oriented away from the coupling element 4, wherein the arresting arrangement protrudes into an axial bore hole 15 of the coupling housing 12. Thus, the arresting arrangement 14 includes a pinion 16 which is run through the axial bore hole 15 of the coupling housing 12. The pinion 15 includes a flange 17 which contacts a face of the coupling housing 12 and closes the axial bore hole 15. In the longitudinal axis 18 of the coupling element 4 and the handle element coupling 5 and thus also of the axial bore hole 15 and of the pinion 16 a bolt 20 is arranged in the pinion 16 in a longitudinal bore hole 19 wherein the bolt is movable by a plunger 21 against a force of a spring 26 which presses against the pinion 16 in a cavity 22 wherein the bolt 20 is movable in the axial direction towards the coupling element 4. The bolt 20 is supported in a sleeve 23 which protrudes through a bore hole 34 in the face wall 24 of the coupling element 4 into a cavity arranged in the coupling element 4. In the sleeve 23 there are arresting devices 27 configured as bearing balls which move into an unlocking portion 28 at the bolt 20 configured as a recess when the bolt 20 moves in a direction towards the coupling element 4, which facilitates an axial movement of the coupling element 4 away from the pinion 16. Thus, the outer teething 8 at the coupling element 4 comes out of engagement from the inner teething 29 arranged in the coupling housing 12. This movement, however, is prevented by the interlocking devices 10 of the push-pull interlocking wherein the interlocking devices 10 engage the recess 9 of the coupling element 4. Thus, a movement of the coupling element terminates at another end 31 of the recess 9 illustrated in FIG. 3. A complete pull out of the coupling element 4 from the handle element coupling 5 is only possible when the movement of the push-pull locking ring 11 against a force of the spring 13 simultaneously facilitates that the locking devices 10 can move out of the recess 9 into the recess 30 that is arranged in the push pull interlocking ring 11.
