Abstract
The invention belongs to an embedded spanner for screwing up or down a bolt and a nut. The invention aims to solve the defects that the existing box spanners have multiple standards, one box spanner is only suitable for the bolt and nut with one standard, and an operator needs to purchase and carry the box spanners of multiple standards during the actual use. The invention provides a multi-model spanner suitable for the bolts and nuts of multiple standards. 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; the spanner head is provided with a hole; the module is <-shaped; a lug is arranged at one end of the module; the hole wall at one end of the hole in the spanner head is provided with a slot matched with the lug on the module and used for fixing the embedded module; the spanner head is arranged at one or two ends of the spanner body; the module can be made to different sizes and standards for being applied to the bolts and nuts of different sizes.
Description
Technical field
The present invention 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 weak point that the object of the invention is need purchase when bolt and nut many for existing double offset ring spanner specification, that double offset ring spanner is only applicable to a kind of specification causes actual use the double offset ring spanner that carries multiple specifications, provides a kind of specification can regulate, can be applicable to simultaneously the polytypic spanner of plurality of specifications bolt and nut.
The present invention 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 present invention 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.
