Description
Technical field
This utility model belongs to hardware ＆ tools technical field, is related to a kind of spanner, particularly to a kind of labour-saving spanner.
Background technology
Spanner is a kind of conventional installation and extracting tool, twists the manual work of bolt, screw, nut using lever principle
Tool, in the one or both ends grip bolt of shank or the opening of nut or set hole, during use, threadingly direction of rotation exists spanner
Shank applies external force, just can twist bolt or nut.And when making to screw up with a wrench screw or nut on pipeline, usually because
Pipeline is located at the position of the narrow space such as corner, and makes user cannot use strength completely, leads to bolt or the nut cannot be complete
One-tenth is tightened, and leaves safe hidden danger.
Content of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, there is provided a kind of labour-saving spanner.
The purpose of this utility model can be realized by following technical proposal：A kind of laborsaving wrench, including impact wrench, its
It is characterised by, the lower section of described re-tensioning wrench is provided with matched back-up wrench, and described impact wrench includes tightening
Head with tighten handle, described back-up wrench includes fixing head and fixed handle, and the middle part of described fixed handle is installed with
Fixing axle, the described middle part tightening handle has the guide rail of arc-shaped, and the center of circle of described guide rail is located in tappet head
Center portion position, described fixing axle can be along slide in guide rail.
The operation principle of this labour-saving spanner：When needing to tighten bolt or the nut on pipeline, by the tappet head of impact wrench
It is enclosed within bolt or nut, the fixing head of back-up wrench is enclosed within pipeline, prop up back-up wrench on the other hand, another handss rotate twists
Spanner, you can realize tightening or dismantling of bolt or nut.This spanner is by the impact wrench cooperating and back-up wrench group
Become, when narrow space is tightened or dismantles bolt or nut on pipeline, can have an effect by back-up wrench, and have and use lever
Principle, can be tightened using less power or dismantle the bolt on pipeline or nut.
In above-mentioned labour-saving spanner, described tightens handle to the direction bending away from back-up wrench.
In above-mentioned labour-saving spanner, the top of described fixing axle has two pieces of fixed blocks for fixing guide rail.
Compared with prior art, this spanner has labour-saving advantage.
