Socket wrenches are known and are used to tighten or loosen screws with a square or hexagonal head, the square extension having a square or hexagonal recess which is placed on the square or hexagonal head of the screws the plug-in attachment is designed as a square pin, which is inserted into a corresponding recess in the jaw chuck. Each key according to the present innovation should be tightened or loosened.

The socket wrench according to the innovation is in Pig. 1 and 2 shown in the accompanying drawing.

The socket wrench consists of a box-like upper part 1 with handles 3, 3 'which are screwed into eyes 12, 12' on the upper part 1. In the center of its interior there is a gear 5 firmly connected to it. The connection consists of a pin 8 , on which the gear 5 is attached with a spring 15. The gear 5 is secured against axial displacement by a shoulder H on the pin 8. The pin 8 is firmly connected to it by screwing its Gev / indestücks 20 into the upper part 1 Lock nut 21 is provided as a safety device. The upper part 1 can be rotated around a box-like lower part 2, which contains two gears 6, 7 in its interior. A shaft 4 adjoins the lower part 2 in its center. This shaft has a bore 16 for an insert 17 with a plug-in attachment in the form of a square pin 18, which can be inserted into a recess of a pivot bankbak-K.enfutter is provided, and a shear pin 19 in a "bore 19 'which holds the plug-in projection 17 in the bore 16. The ochej pin 19 prevents overstressing of the square pin M by shearing. Instead of the four-sided 18 as plug-in projection can be connected to the rJin ^ atz 17 is a hexagon orier Vierkanntausneh · mung be provided Sechskantküpfen to be solved if, for example tight-fitting bolts with square or hexagonal ·.

The fixed. Gear 5 on the upper part 1 is singly handle

with the smaller gear 6 and this with the gear of the same size 7.The gear? meshes with the internal teeth :: 11 in the lower part 2 The upper part 1 is secured against axial displacement on the lower part 2 with a snap ring 13.

The gears 5,6,7 can be made of suitable plastic and by the arrangement of the gears 5,6,7 and the internal teeth 11 ensures that when rotating the upper part 1 with the Handle 3,3 'the lower part 2 with the shaft 4 in the same Direction of rotation is moved with the upper part 1, the lower part 2 and the handles 3, 3 'are made of suitable metal, e.g. steel.

The inserts 18 with different sizes of plug lugs 17 könr.en rapidly against each other in the bore 16 replaced, v / hen the jcherstift 19 at a Onde as a screw and at the other: ^r .nde as cord head formed .The screw can then in a threaded be screwed on one site of the bore 19 '. The shear pin 19 consists of a suitable material, such as steel, in the same way as the shaft 8 with inserts 17 and lugs 18.
