Abstract
The utility model belongs to the technical field of maintaining tools, and mainly relates to a crank spanner, which is especially suitable for operations in narrow spaces and consists of a spanner jaw (1) and a handle (2). The crank spanner is characterized in that the handle (2) has a 'Z'-shaped structure bent by twice. The crank spanner has the characteristics of simple structure as well as time and effort saving, and can lead the spanner jaw to easily block a nut in narrow spaces. Moreover, spare parts can be conveniently mounted or dismounted by rotating the tail end of the 'Z'-shaped handle. The crank spanner solves the problem that a common spanner can not be used, improves the working efficiency, and reduces the working intensity.
Description
Technical field
The utility model belongs to the maintenance tool technical field, relates generally to a kind of crank-type spanner, is particularly useful for the operation of narrow space place.
Background technology
At present, during the bolt of maintenance personal in the pipeline at installation and removal narrow space place or fastening, dismounting small space, common spanner can't use, if free-hand operation, strength is limited, can't reach fastening requirement is installed, and also can't disassemble bolt sometimes.
Summary of the invention
The purpose of this utility model is to propose a kind of crank-type spanner, solves the difficult problem of operating personnel at narrow space place operational difficulty, and is time saving and energy saving, increases work efficiency.
The utility model is finished the technical scheme that its invention task taked:
A kind of crank-type spanner, described pinch bar are " Z " font structure of twice bending.
Twice bending angle of described pinch bar is 90 °.
A kind of crank-type spanner that the utility model proposes has simple in structure, time saving and energy saving characteristics, can make to pull mouth block nut, the end of turning handle, installation or removal part easily easily in narrow space.Solve the problem that common wrench can't be used, improved operating efficiency, reduced labour intensity.
