Description

Multi-functional active spanner

Technical field

The utility model relates to a kind of adjustable wrench, particularly a kind of multi-functional active spanner.

Background technology

At present, the adjustable wrench kind on the existing market is more and more, and function is also more and more complete, and this allows operative employees economize many working times, has also improved operating efficiency greatly.But when electricians need to use the adjustable wrench of different size, just must prepare the whole of plurality of specifications adjustable wrench, because of adjustable wrench has their certain volume and weights, band will be given certain inconvenience of self bringing of electricians too much, has also reduced electricians' job morale and operating efficiency.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of multi-functional active spanner, in use, can change the adjustable wrench head of different model as required, and the many usefulness of a tool have improved operating efficiency.

The utility model technical scheme that adopts of dealing with problems is: a kind of multi-functional active spanner, comprise head and handle, described head is made of the movable part that contains worm screw, worm gear and fixed part, be provided with jockey between described head and the handle, the supporting use of the head of described handle and one or more different sizes.

As further improvement, described head is that sleeve is connected with jockey between the handle.

As further improvement, the tail end that described sleeve is connected to head extends a bit of cylinder, be provided with an elastic tension pearl below cylinder, the front end of handle is provided with the cylindrical drum that a bit of cylinder a bit of and on the head matches, and realizes that sleeve connects.

As further improvement, the movable part of described head can make its upper and lower end face exchange by its worm screw, and its upper and lower end face is respectively plane and serrated face.

In the utility model, stated the head specifications such as ", 12 " that can be designed as 6 ", 8 ", 10, with the supporting use of the same handle; And specification is respectively 6 ", 8 ", the adjustable wrench head of 10 ", 12 " is also can be respectively supporting and as independent adjustable wrench with handle; Certainly these adjustable wrench heads itself also can be used as the adjustable wrench use.

In addition, the utility model makes the work suitable application area of spanner extend to pipe spare by setting up the zigzag working face.

The beneficial effects of the utility model are: head and handle can freely shirk, and change the head of different model, make the scope of application bigger, carry more conveniently, and the many usefulness of a tool have improved operating efficiency.
