Working with the screwdriver also serves as a guide, and the screwdriver blade cannot, as with an ordinary screwdriver, slide off the front of the screw groove. Preferably they have Socket wrench 6 outside and inside the same cross-sectional shapes, so that more can be put on Sizes of socket wrenches such as 14 and IS in FIG. 4 and 5, is guaranteed. To the adherent Connection of two socket wrench sizes known designs can be provided should not be the subject of the invention. For example, a slot 13 enables spreading or squeezing the plug-in or plug-in Socket wrench.

The screw socket wrenches 6 are angular in the effective length α and round in the remaining part b. This creates a stop 22 for the socket wrenches 14 and 15.

Claims (1)

Patent claims: 1. Screwdriver with a screwdriver blade surrounding screw plug-in connector, which by means of a guide sleeve on the Screwdriver shaft can be pushed back against spring force and taken by a driver is connected, characterized in that the driver ^ rch a Transverse groove (9) at the bottom of a stepped hole in the guide sleeve (6 ') and one in it can be trained without difficulty in the manufacture of the screw socket wrench, and also the shoulders to be provided on the screwdriver blade do not result in any additional work; because this Shoulders do not need to be stronger and wider Uin than they are usually present. These can also be used to support the back Screw plug-in connectors are used to pull the screwdriver blade over the screw To let the socket wrench protrude if anything be worked with the screwdriver blade
