With angle grinders, especially the commercially available one-hand angle grinders, interchangeable tools such as cutting discs, grinding discs, wire brushes, pot stones and the like can be clamped to the drive spindle. Depending on the tool design, either open-end wrenches with a specific jaw width and/or two-hole nut wrenches can be used. The latter are used especially with square nuts, which have two diametrically opposed holes to accommodate two plug pins of the two-hole nut wrench. In practice, however, it proves to be annoying that a number of different wrenches have to be kept ready for the various tools assigned to the angle grinders;

The object of the invention is to create an inexpensive combination wrench that is suitable for clamping all types of angle grinder tools.

The combination wrench according to the invention is characterized by a double-bent steel sheet strip with a long handle, a short handle and a short working arm designed as a two-hole nut turning head, and by a further arm on the handle.

formed two-hole nut turning head, whose plug ^- in tabs are directed opposite to the plug-in tabs of the working leg I s, and through several different open-end wrench recesses on the handle leg I *

The additional two-hole nut turning head is advantageously arranged on the area of the handle leg adjacent to the middle leg. The handle leg consists of a narrow handle part and a wider working part on which the L-shaped recesses for the open-end wrenches are formed on opposite long sides. The dimensions of the two-hole nut turning heads and the open-end wrench recesses are of course matched to the usual, largely standardized dimensions of the fastening nuts, so that the combination wrench can be used universally on angle grinders.

In a further embodiment of the invention, a hanging hole in the form of a hexagon opening set at the corner can be provided at the free end of the handle leg, so that the combination wrench can also be used as a wrench with this hexagon opening.

Furthermore, a crown closure opener consisting of a crown holder and a crown edge gripping nose can also be arranged on the working part.

Finally, according to the invention, it can be provided that, in order to save weight and to provide a better overview during handling, the sheet steel strips are each provided with a recess or cutout between the plug pins, the cutout in the handle leg extending beyond the middle of the middle leg.

The subject matter of the invention is described in more detail below using an exemplary embodiment shown in the drawing. Shown in the drawing!

Fig. 3 is a front view seen in the direction of arrow III in Fig. 2.

6-way combination wrench I consists of a double-bent steel sheet strip with a long handle leg I 1, middle leg 2 and short working leg I 3. The working leg 3 is divided by a central longitudinal recess 4 into two prongs 5, 6, each of which has a plug-in pin 7, 8. The working leg I 3 is thus designed as a first two-hole nut rotating head I, with the pins 7, 8 aligned parallel to the middle leg 2 and facing away from the handle leg I 1. This rotating head I is used, for example, when a pot-shaped tool, such as a pot stone, is placed with its base on the drive spindle and is firmly clamped by means of a two-hole nut located in the pot cavity.

The handle leg 1 consists of an actual, narrower handle part 9, which is provided with a roughening 10 to improve its grip, and of a comparatively wider working part 11, on which on opposite longitudinal sides

two differently sized wrench recesses 12, 13 are cut out. At its end area adjacent to the middle leg 2, the working part 11 is designed as a further two-hole nut turning head II, whose plug pins 14, 15 are located on the top of the handle leg I and are directed opposite the plug pins 7, 8.

On the working part 11, a crown lock opener 1ö with a crown holder 17 and a crown edge gripping nose 18 is also provided on one longitudinal edge. Finally, a hanging loop is provided on the free end of the handle 9.

To reduce the weight, the steel sheet strip between the plug pins 7> 8 with the recess 4 and between the plug pins 13, 14 with a recess

20, wherein the recess 20 extends beyond the edge of the middle leg 2.
