Abstract
The utility model discloses an embedded spanner for screwing or unscrewing bolts and nuts. In order to overcome the defect that double offset ring spanners of multiple specifications need to be purchased and carried in the actual use due to the facts that the existing double offset ring spanners have the multiple specifications and one double offset ring spanner is only applicable to the bolt and nut of one specification, the multi-model embedded spanner has the adjustable specifications and can be applicable to the bolts and nuts of the various specifications at the same time. The embedded spanner comprises a spanner body and a module matched with the spanner body. The spanner body comprises a handle and a spanner head arranged on the handle. A hole is formed in the spanner head. The module is in a < shape. One end of the module is provided with a convex lug. A groove matched with the convex lug on the module is formed in the hole wall of one end of the hole in the spanner head, so that the module is fixedly embedded into the spanner head. The spanner head is arranged at one end or two ends of the spanner body. The module can be manufactured into different specifications so as to be suitable for the bolts and nuts of the different sizes.
Description
Technical field
The utility model relates to hardware & tools technical field, especially for screwing or the embedded spanner of one of the nut that loosers a bolt.
Background technology
Double offset ring spanner is a kind of screwing or the instrument of the nut that loosers a bolt, and conventional double offset ring spanner is pulled a mouthful size and fixed, and can only be used in a kind of bolt and nut of specification.In the application of metric system bolt and nut, use in a large number again bolt and nut made in Great Britain in recent years, made the specification of bolt and nut double increase, in the time of installation or removal, need to be equipped with the double offset ring spanner of all size, increased acquisition expenses, and carried inconvenience.
Summary of the invention
The purpose of this utility model is the weak point that bolt and nut many for existing double offset ring spanner specification, that double offset ring spanner is only applicable to a kind of specification need be purchased the double offset ring spanner that carries multiple specifications while causing actual use, provides a kind of specification can regulate, can be applicable to simultaneously the polytypic spanner of plurality of specifications bolt and nut.
The utility model completes in the following way: a kind of embedded spanner, and this embedded spanner comprises that wrench body and the module matching, described wrench body comprise handle and be located at the driving end on handle, described driving end is provided with hole.
In the embedded spanner of described one, described module is " < " shape, described module one end is provided with lug, and the hole wall of the one end, hole on described driving end is provided with the groove matching with the lug in described module, in order to fixedly embedded module.
In the embedded spanner of described one, described driving end is located at the one or both ends of described wrench body.
In the embedded spanner of described one, described module can be made to the specification that size differs, for the different bolt of size dimension and nut.
While adopting the utility model to carry out the installation and removal of bolt and nut, according to the selected module that size matches with it of the specification of bolt and nut, the groove that the lug of selected module is aimed on driving end inserts, now the hole on module and driving end forms a hexagonal hole, with bolt and nut sizableness, can carry out installation or removal work.
