Description

Multiple screw tool

The innovation concerns a hand- or machine-operated screwing tool of the type known from the socket wrenches, with several screwing points arranged on the tool body for operating screws or similar screw elements.

Screwing tools of this type, i.e. those with several screwing points arranged on a common tool body, e.g. screwdriver blades or socket wrench points, are known in various ways. They serve the purpose of having several screwing points of different types or sizes available on a common tool body in order to reduce the range of tools or to have the right or required tool to hand for one or other tool use with just one access. Various tool combinations have already been provided which have found advantageous use for the above-mentioned purpose.
The task and purpose of this innovation also results from similar needs.

The multiple screwing tool to be developed should be designed in the manner of a so-called socket and be designed in such a way that different, specially coordinated work operations can be carried out with only one tool body, without having to change the tool type and size for different screw connections.

This object is achieved according to the invention with screwing tools, as indicated by the characteristic design features according to the claims and as illustrated by the associated drawings of some preferred embodiments of this tool for better understanding.

The drawing represents

Fig. 1 a socket wrench-like special tool for

Operation of screws with Torx action point in combination with an internal and external socket with any screw profile and wrench size in longitudinal section, and in

Fig. 2 a socket wrench-like special tool with a

inside and an external screw profile, and

Fig. 3 a partial longitudinal section of the tool head part

according to Fig. 2

Both tool designs can be operated with conventional adapter-shaped intermediate links both by hand and with mechanical screw drives.

The tools according to Fig. 1 each have the basic shape of a socket wrench in the form of a socket 8, in whose cylindrical or rod-like, socket-wrench-like tool body 1 a polygonal profile 2 is incorporated axially for the displaceable reception of a screw insert 3.

The screw insert 3 can be designed as a screw bit 4 or as a socket 8 with a multi-edge effective profile. It is subject to the action of a compression spring 6 in the axial direction in order to make room for an external multi-edge effective point 7 attached to the tool body 1 or a socket 8 that can be moved in the multi-edge profile 2 of the tool body 1.

Claims (1)

1. Screwing tool of the type known from socket wrenches, with several screwing points arranged on the tool body, characterized by the following features: - on the socket wrench-like tool body ( 1 ) according to Fig. 1, a polygonal working point ( 7 ) is arranged on the outside, for example in the form of a socket ( 8 ), while - in a polygonally profiled axial bore of the tool body ( 1 ) a screw insert ( 3 ) in the manner of a screw bit ( 4 ) designed, for example, as a Torx action point is arranged so as to be longitudinally displaceable and supported against a compression spring ( 6 ); wherein in a further design variant according to Fig. 2 - an internal screwing point ( 2 ) is incorporated at the end of the socket-type tool body ( 1 ), in which - a socket ( 8 ) is inserted so as to be longitudinally displaceable against a spring ( 6 ), the socket ( 8 ) carrying an identical or reduced polygon.
