Description

Technical area

The present invention relates to a tool for craftsmen, in particular a multi-purpose wrench.

Technical background

Wrenches are tools that use the law of levers to tighten screws, nuts and other similar parts, or vice versa loosely screw to loosen them. The following types of wrenches are commonly used in the market: ring spanners, hex keys, open-mouth keys, multi-routing keys, dual purpose keys, container keys, key wrenches, general-purpose keys, oxygen cylinder keys and L-shaped keys, etc. However, common wrenches are often difficult to adapt them to the different positions of the nuts. Furthermore, they also lack the function to hammer or cut if necessary.

Content of the invention

The present invention has for its object to provide a multi-purpose wrench, which overcomes the shortcomings of the wrench of the prior art.

The object of the present invention is solved by the following technical concept:
The multi-purpose wrench according to the invention comprises a first key head and a handle, wherein the first key head is screwed together by screw thread with the handle. The first key head has a first polygonal hole in its center. On the left side of the first key head recess a key mouth is provided. Furthermore, the first key head still has a hammer head and a cutting edge, which are firmly screwed by means of screws to the first key head and can be demounted if necessary. The scabbard is triangular. The hammer head and the cutting edge serve to hammer or cut objects as needed during work.

At the other end of the handle 2 a round second key head is attached, which has a second polygonal hole in its center. The first polygonal hole and the second polygonal hole and the key mouth are used to edit different nuts or nuts in different positions. At the junction between the handle and the first key head an intermediate stage is still provided.

The advantages of the present invention are that different nuts or screw nuts can be machined in different positions by the combination of the first and the second polygonal hole and the keyhole, so that the wrench according to the invention can flexibly adapt to different work situations. Furthermore, the functionality of the wrench according to the invention by the on and demountable additional parts, namely the hammer head and the cutting edge, extended to additional functions.

embodiment

In the following an embodiment of the present invention will be explained in more detail with reference to the drawing.

As 1 shows, the multi-purpose wrench according to the invention comprises a first key head 1 and a handle 2 , where the first key head 1 via screw thread with the handle 2 is screwed together. The first key head 1 has in its middle a first polygonal hole 11 on. At the left side of the first key head 1 is aussparungsmäßig a key mouth 12 intended. Furthermore, the first key head 1 another hammerhead 13 and a cutting edge 14 on that over screws on the first key head 1 firmly screwed and can be dismantled if necessary. The scabbard 14 is triangular. The hammerhead 13 and the cutting edge 14 serve to hammer or cut objects as needed during work.

At the other end of the handle 2 is a round second key head 21 attached, in its center a second polygonal hole 211 having. The first polygonal hole 11 and the second polygonal hole 211 as well as the key mouth 12 serve to work different nuts or nuts in different positions. At the junction between the handle 2 and the first key head 1 is still an intermediate 22 intended.

The present invention is not limited to the embodiment shown above. The embodiment shown above is illustrative only and has no limiting effect. Other embodiments that are identical or equivalent to the technical concept of the present invention are also covered by the claims of the present invention.
