Description
Technical field
The present invention relates to a kind of spanner more particularly to a kind of Polygonal wrenchs becoming size.
Background technology
Spanner extensive application in production and living, Polygonal wrench（Such as die nut）It is more convenient when in use, but
Existing Polygonal wrench is mostly single size, i.e., a spanner corresponds to a kind of size, therefore is needed for multiple in life and work
Spanner is to meet installation（Or dismounting）The demand of different size bolt/nuts, that is, increase expense, also using and protecting to tool
Pipe is made troubles.
Invention content
The purpose of the present invention is to overcome the above shortcomings and to provide a kind of Polygonal wrenchs becoming size.
To achieve the above object, technical solution provided by the invention is as follows：A kind of change size spanner, including cyclic structure
One, cyclic structure two and handle, the cyclic structure one are equipped with the position-limiting unit structure that quantity is three or three or more, institute
Stating position-limiting unit mechanism can rotate around cyclic structure one, and the cyclic structure two is equipped with multiple bulge-structures, the cyclic annular knot
It can make relative rotation motion of driving system between structure one and the cyclic structure two, during the rotational motion, the bulge-structure can push away
The position-limiting unit structure is moved to rotate around the cyclic structure one.
The alternative of the present invention is that the change size Polygonal wrench is additionally provided with elastic force apparatus, for example, torque spring or
Torsion shrapnel or tension spring etc.；The elastic force of the elastic force apparatus acts on the position-limiting unit structure.
The alternative of the present invention is that the cyclic structure one is connect with the handle.
Another alternative of the present invention is that the cyclic structure two is connect with the handle.
The alternative of the present invention is that the position-limiting unit number of structures is six.
The alternative of the present invention is that the position-limiting unit symmetrical configuration is distributed in the loop configuration one.
The operation principle of the present invention is, is installing（Or dismounting）When bolt/nut, the position-limiting unit structure with
Bolt/nut matches, and acts power to bolt/nut in rotating spanner, to allow bolt/nut to rotate；For
The bolt/nut of different characteristic size, by making the cyclic structure one and cyclic structure two rotate, to make limit list
Meta structure rotates, to change the working size corresponding to position-limiting unit structure（That is, the spiral shell that position-limiting unit mechanism can coordinate
The size of bolt/nut）, realize the change size of Polygonal wrench.
Beneficial effects of the present invention have：Spanner of the present invention can correspond to multiple bolt/nut sizes, with better function；This hair
Bright spanner structure is simple, easy to operate.
Description of the drawings
Fig. 1 is the change size spanner structure schematic diagram that embodiment provides；
Fig. 2 is another working condition for the change size spanner that embodiment provides.
Reference numeral：1- cyclic structures one；2- cyclic structures two；3- handles；4- position-limiting unit structures；5- bulge-structures；
6- elastic force apparatus.
Specific implementation mode
Technical scheme of the present invention is clearly and completely described below in conjunction with attached drawing, it is clear that described implementation
Example is a part of the embodiment of the present invention, instead of all the embodiments.Specific design in this example cannot regard in the nature of things
For the essential feature of the present invention, or it is considered as limiting the scope of the present invention.Based on the embodiments of the present invention, this field is general
The every other embodiment that logical technical staff is obtained without making creative work belongs to what the present invention protected
Range.
In the present invention, the position-limiting unit structure that " position-limiting unit mechanism can be rotated around cyclic structure one " refers to can be tied around ring-type
Some shaft rotation on one place coordinate system of structure is dynamic, and the relative position of the axis and the point in cyclic structure one is kept fixed, which can
Think real axis（Pass through the point in cyclic structure one）, or the imaginary axis（Do not pass through the point in cyclic structure one）.
Embodiment
Shown in Figure 1, the present embodiment provides a kind of change size spanner, Fig. 1 is its structural schematic diagram, becomes size spanner master
It to include cyclic structure one（1）, cyclic structure two（2）And handle（3）；Loop configuration one（1）With loop configuration two（2）It can make phase
To rotational motion, position-limiting unit structure is equipped in cyclic structure one（4）, position-limiting unit structure（4）It can be around loop configuration one（1）
Rotation, position-limiting unit structure（4）Quantity be more than or equal to 3, in fig. 1, quantity be 6, be symmetrically distributed in cyclic annular knot
Structure one（1）On；In loop configuration two（2）It is equipped with bulge-structure（5）, when cyclic structure one（1）With cyclic structure two（2）Turn
During dynamic movement, bulge-structure（5）Position-limiting unit structure can be pushed（4）Around cyclic structure one（1）Rotation；It is also set on spanner
Elastic device（6）, elastic force apparatus（6）Elastic force act on position-limiting unit structure（4）On, active force makes the work of entire spanner
There are widened trend, elastic force apparatus as size（6）Can be torque spring or torsion shrapnel or tension spring etc., in Fig. 1,
Elastic force apparatus（6）For torque spring；Cyclic structure one（1）Or cyclic structure two（2）With handle（3）Connection, it is in Fig. 1, cyclic annular
Structure one（1）With handle（3）Connection.In Fig. 1, cyclic structure one（1）For inner ring, cyclic structure（2）For outer shroud, the present invention
It can be by cyclic structure one（1）For outer shroud, cyclic structure（2）For inner ring.In Fig. 1, cyclic structure（1）Straight slot is offered, protrusion
Structure（5）Across straight slot and position-limiting unit structure（4）Contact（Unnecessary is the whole contact in rotation process）；The present invention also may be used
Bulge-structure is realized by other forms（5）Across straight slot and position-limiting unit structure（4）Contact, such as by cyclic structure（1）
And cyclic structure（2）Dislocation up and down is carried out, by bulge-structure（5）It is set to cyclic structure（1）Above or below.
Pass through rotary annular structure two（2）, push position-limiting unit structure（4）Rotation, reach another working size.Figure
2 be another working size for becoming size spanner, it can be seen that the corresponding work ruler of change size spanner working condition shown in Fig. 2
It is very little to be less than the corresponding working size of change size spanner working condition shown in FIG. 1.
