Description
Technical field
The present invention relates to a kind of spanner more particularly to a kind of Polygonal wrenchs for becoming size.
Background technique
Spanner extensive application in production and living, Polygonal wrench (such as die nut) 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 in life and work for multiple
Spanner increases expense, also using and protecting to tool to meet the needs of installation (or disassembly) different size bolt/nuts
Pipe is made troubles.
Summary of the invention
The purpose of the present invention is to overcome the above shortcomings and to provide a kind of Polygonal wrenchs for becoming size.
To achieve the above object, technical solution provided by the invention is as follows: a kind of change size spanner, includes 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 be pushed away
The position-limiting unit structure is moved to rotate around the cyclic structure one.
Optinal plan of the invention is that the change size Polygonal wrench is additionally provided with elastic force apparatus, for example, torque spring or
Torsion elastic slice or tension spring etc.；The elastic force of the elastic force apparatus acts on the position-limiting unit structure.
Optinal plan of the invention is that the cyclic structure one is connect with the handle.
Another optinal plan of the invention is that the cyclic structure two is connect with the handle.
Optinal plan of the invention is that the position-limiting unit number of structures is six.
Optinal plan of the invention is that the position-limiting unit symmetrical configuration is distributed in the ring structure one.
Working principle of the invention is, in installation (or disassembly) bolt/nut, the position-limiting unit structure with
Bolt/nut matches, and generates active force to bolt/nut in rotating spanner, so that bolt/nut be allowed to rotate；For
The bolt/nut of different characteristic size, by making the cyclic structure one and cyclic structure two rotate, to keep limit single
Meta structure rotation, to change working size corresponding to position-limiting unit structure (that is, the spiral shell that position-limiting unit mechanism is able to cooperate
Bolt/nut size), realize the change size of Polygonal wrench.
The beneficial effects of the present invention are as follows: spanner of the present invention can correspond to multiple bolt/nut sizes, it is with better function；This hair
Bright spanner structure is simple, easy to operate.
Detailed description of the invention
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.
Appended drawing reference: 1- cyclic structure one；2- cyclic structure two；3- handle；4- position-limiting unit structure；5- bulge-structure；
6- elastic force apparatus.
Specific embodiment
Technical solution 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 essential feature of the 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
Logical technical staff every other embodiment 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 axis rotation on one place coordinate system of structure, the relative position of the axis and the point in cyclic structure one are kept fixed, which can
Think real axis (by the point in cyclic structure one), or the imaginary axis (does 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)；Ring structure one (1) can make phase with ring structure two (2)
To rotational motion, position-limiting unit structure (4) are equipped in cyclic structure one, position-limiting unit structure (4) can be around ring structure one (1)
The quantity of rotation, position-limiting unit structure (4) is more than or equal to 3, and in fig. 1, quantity is 6, is symmetrically distributed in cyclic annular knot
On structure one (1)；Bulge-structure (5) are equipped in ring structure two (2), when cyclic structure one (1) and cyclic structure two (2) turn
During dynamic movement, bulge-structure (5) can push position-limiting unit structure (4) to rotate around cyclic structure one (1)；It is also set on spanner
Elastic device (6), the elastic force of elastic force apparatus (6) act on position-limiting unit structure (4), and active force makes the work of entire spanner
There is widened trend as size, elastic force apparatus (6) can be torque spring or torsion elastic slice or tension spring etc., in Fig. 1,
Elastic force apparatus (6) is torque spring；Cyclic structure one (1) or cyclic structure two (2) are connect with handle (3), cyclic annular in Fig. 1
Structure one (1) is connect with handle (3).In Fig. 1, cyclic structure one (1) is inner ring, and cyclic structure (2) is outer ring, the present invention
It can be outer ring by cyclic structure one (1), cyclic structure (2) is inner ring.In Fig. 1, cyclic structure (1) offers through slot, protrusion
Structure (5) passes through through slot and contacts (unnecessary is whole contact during rotation) with position-limiting unit structure (4)；The present invention can also
Realize that bulge-structure (5) pass through the contact of through slot and position-limiting unit structure (4) by other forms, such as by cyclic structure (1)
Dislocation up and down is carried out with cyclic structure (2), bulge-structure (5) is set to above or below cyclic structure (1).
By rotary annular structure two (2), the rotation of position-limiting unit structure (4) is pushed, another working size is reached.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.
