Abstract
The utility model relates to a wrench. The wrench comprises a handle and is characterized in that a wrench cap is arranged on one end of the handle or wrench cap are arranged two ends of the handle. A nut chucking cavity is formed on the wrench cap. One end of the nut clamping cavity is open, and the other end of the nut clamping cavity is provided with a bottom. The wrench has the advantages of being used in a narrow space, being capable of avoiding dropping of a screw and being efficient, practical and simple in structure.
Description
Technical field
The present invention relates to a kind of spanner, be specifically related to a kind of spanner that is applied to bolt disassembly under the small space.
Background technology
Along with the development of science and technology, the use of many special equipments is more and more extensive.On some special equipments; always having some subsidiary bodies around when needs are installed some anchor clamps or workpiece stops; so that need the surrounding space of Seeding location to become very narrow and small; staff can't freely be put to good use; at this moment the double offset ring spanner of operation in narrow space has just appearred being used for; although but use double offset ring spanner can solve the difficult problem of operation in narrow space; but screw is not when buckling bolt hole silk mouth in the process of operation; the situation that often can drop; when screw quantity is many, can have a strong impact on installation progress.
The utility model content
The utility model purpose is both can use at small space for the defective that overcomes prior art provides a kind of, can prevent again efficient, practical, the simple in structure spanner that screw drops.
The utility model discloses following content:
A kind of spanner comprises handle, and the one or both ends of described handle are provided with the spanner cap, forms nut chucking chamber on the spanner cap, and an end opening other end in nut chucking chamber is provided with the end.
Described nut chucking chamber is interior hexagonal die cavity, is provided with through hole at the end of interior hexagonal die cavity.
Described nut chucking chamber is the plum blossom hole die cavity, and the plum blossom hole die cavity is made of cylindrical cavity and the semicircle axial groove that is arranged on the cylindrical cavity interior sidewall surface, is provided with through hole at the end of plum blossom hole die cavity.
Described through hole is cylindrical hole, and its internal diameter is less than the internal diameter in nut chucking chamber, and the thickness at the end in nut chucking chamber is greater than 0.5mm.
The thickness of the side walls in described nut chucking chamber is greater than 0.5mm.
The utlity model has following advantage: can prevent effectively that 1, screw from not dropping when buckling bolt hole silk mouth, the utility model is provided with the spanner cap at the chucking position, described spanner cap can prevent effectively that screw from dropping, when needs are installed screw, can directly screw be placed in the spanner cap of the utility model spanner, stop that by the spanner cap screw falls down spanner, and then screw is installed in the silk mouth of bolt hole by the chucking position of spanner; 2, the chucking position of the utility model spanner is plum blossom hole or inner hexagonal hole, can be applicable to operation in narrow space; 3, operating efficiency can be saved time, effectively be increased to the utility model spanner, owing to being provided with the spanner cap that prevents that screw from dropping, therefore screw drops and chooses the process of screw in the time of can greatly reducing installation, when carrying out a fairly large number of installment work, can effectively reduce the set-up time; 4, the utility model spanner two ends are equipped with the chucking position, can be used for installing simultaneously the screw of two kinds of models; 5, the utility model spanner is simple in structure, has just established an integrated spanner cap on original spanner clamping unit more; 6, reduce artificial impact on equipment, when the installation number of times was more, staff inevitably caused corrosion to equipment, affect the use of equipment, and the unique design of the utility model spanner has been avoided the releasing number of times of screw and staff, thereby has effectively alleviated the generation of above-mentioned situation; 7, result of use is stable, during reality is produced, had artificially the problem that solves this respect once to attempt the use Magnetized Material, but this method neither be very stable.
