The support elements 1140 are formed as knob-shaped projections and each have a substantially conical outer surface. Furthermore, the device 1100 has a shank 1150, which protrudes centrally from the head 1120 in the fastening direction 1110, so that the support elements 1140 are inclined towards the shank. At its end opposite the head 1120, the shaft 1150 has a point 1160 which is provided with reinforcing ribs 1170. The transition 1155 from the head 1120 to the shaft 1150 is frusto-conical.

Detecting features of the device 1100 include, for example, the inner or outer diameter of the head 1120, the diameter or length of the shaft 1150, the geometric shape of the tip 1160, the number, size or geometric shape of the support members 1140 and / or in non-illustrated embodiments the number, arrangement or shape of breaks in the head 1120.

In non-illustrated embodiments of a driving-in device, the detected consumable is a driving piston and / or a piston brake. In other embodiments, not shown, the image recognition verifies the presence of a geometry that is needed for the function of a set failure detection, to avoid that consumables are used, which override the setting failure detection.

According to an embodiment, not shown, the tool comprises a drill. The consumable is then for example, a drill or a battery.

According to a further embodiment, not shown, the tool comprises a screwdriver. The consumable is then, for example, a screwdriver bit, a screw or a battery.

According to a further embodiment not shown, the tool comprises a grinding device, preferably an angle grinder. The consumable is then, for example, a grinding wheel.

According to a further embodiment, not shown, the tool comprises a saw, preferably a jigsaw or saber saw. The consumable is then, for example, a saw blade.

According to another embodiment, not shown, the tool comprises a vacuum cleaner. The consumable is then, for example, a filter.

The invention has been explained with reference to different hand-held tools. It is understood that the invention is also suitable for other applications. Preferably, the image recognition serves to identify features which are provided for this purpose on a consumable article. Alternatively and also preferably, the image recognition serves to identify features that are inherent in the technology or inherent to the respective consumable, ie that are present anyway.
