Description
Technical field
The utility model relates to spanner, particularly a kind of dismountable interior angle spanner.
Background technology
Interior polygonal bolt has a wide range of applications in various fields because structure is special.Come it is carried out degree of tightness operation for the special spanner of interior polygonal needs, as the most frequently used in the interior polygonal bolt be hexagon socket head cap screw, corresponding spanner also is an inner hexagon spanner.In the prior art, inner hexagon spanner is of a great variety, but all can not finely satisfy the needs that hexagon socket head cap screw is installed with the even twisting moment value.
In the special key of prior art, be the inner hexagon spanner with bending structure the most widely, its structure is that a column is bent, and an end is as the handle of spanner, and the other end is as the force application part of spanner.Because two can be embedded in the interior polygonal bolt, so two ends all can be used as the force side.It is not enough as follows that this kind spanner exists: a spanner can only be applied in a kind of interior corner bolt, and the interior corner bolt of different size need be selected the spanner of same size for use, needs standby a plurality of spanner like this, and operation is also quite complicated.The length of each spanner handle is all fixed, and can not adjust according to the needs of operation site, has limited the range of application of this kind spanner greatly.
On the basis that makes full use of existing instrument, we improve prior art, in conjunction with spanner commonly used on the market, realize the function of even twisting moment value installation hexagon socket head cap screw.
Summary of the invention
The purpose of this utility model is to overcome the problem that interior polygonal spanner of the prior art can not satisfy multiple needs and even twisting moment value installation hexagon socket head cap screw.A kind of interior angle spanner is provided, satisfying the application demand of corner bolt in the different size, and reaches the certainly setting and the application aims of even twisting moment value simultaneously.
The technical solution of the utility model:
A kind of interior angle spanner, comprise spanner handle, the front end of this spanner handle is provided with the loop bar perpendicular to spanner handle, it is characterized in that also comprising dismountable sleeve, one end of this sleeve is for being placed in the groove on the loop bar, column in the center of the other end relative with described groove is fixed with and can be embedded on the polygonal bolt, the rib number of this column is identical with the rib number of described interior polygonal bolt.
Be equipped with a dismountable extension rod on the loop bar of described spanner handle, an end of this extension rod is placed on the loop bar of described spanner handle end, and the other end embeds in the groove of described sleeve.
Described sleeve is a plurality of, and is carved with numbering according to the dimensions of column.
Described spanner is a torque spanner.
The rib number of described column is four or is six or is eight.
Technique effect of the present utility model:
What interior angle spanner of the present utility model adopted is dismountable sleeve, and the specification of sleeve can be changed as required, except of the present utility model have with the corresponding column of interior angle can also use the sleeve of other types, enlarged its scope of application.Also adopted a kind of extension rod in the utility model, the effect of extension rod is the range of application of extending this interior angle spanner under certain applications.Interior angle spanner of the present utility model has also adopted torque spanner as spanner handle, can finish the degree of tightness work of internal corner bolt like this under fixing torque value.
