Specific embodiment
The embodiments of the present invention are described in detail below in conjunction with attached drawing, but the utility model can be by right
It is required that the multitude of different ways for limiting and covering is implemented.
Inventor has been observed that staff goes out often determine the ruler of fastener to be dismounted when maintenance
It is very little, it is therefore desirable to the spanner for carrying plurality of specifications not only increases the weight bearing of staff, and increase purchase spanner at
This.
Inventor is further thought deeply, and the reasons for the above problems are: spanner is both for specific in the prior art
Size design production, dismounting fastener is waited for different bolts or nut, needs the spanner using different size, if
Being capable of providing one kind can spanner compatible with various sizes of fastener, so that it may the weight bearing of staff is reduced, and
Reduce the cost of purchase spanner.
Based on this, inventor proposes a kind of box spanner, and Fig. 1 is that a kind of box spanner shows in the utility model embodiment
Be intended to, please refer to Fig. 1, the utility model proposes a kind of box spanner include: first assembly 1, the second component 2 and third component
3；Second component 2 is connected with first assembly 1, including first end 211, and first end 211 has the first positioning end face 2111,
First positioning end face 2111 is the surface in first end 211 for being in contact with fastener；Third component 3 includes positioning region
31, positioning region 31 has the second positioning end face 311, and the second positioning end face 311 is the table being in contact in third component 3 with fastener
Face, the both ends of positioning region 31 are connected with first assembly 1 respectively, specifically, the both ends of positioning region 31 can be with first assembly 1
It is fixedly connected, is also possible to movable connection, the component for connecting positioning region 31 and first assembly 1 can be rigid member can also
To be flexible piece；First, which positions the corresponding second positioning end face 311 of end face 2111, is arranged, and the first positioning end face 2111 and second is determined
Spacing between the end face 311 of position is adjustable.For the utility model proposes box spanner, in use, first by fastener
It is placed between positioning region 31 and first end 211, fastener can be such as bolt, nut, by adjusting positioning region 31
The distance between first end 211, so that positioning region 31 and first end 211 are gradually close to fastener, final fastener quilt
Positioning region 31 and first end 211 are fixedly clamped, then turnbarrel spanner is to realize the handling of fastener.The utility model mentions
Box spanner out adjusts the first positioning end face 2111 by adjusting the distance between third component 3 and first end 211
With second positioning end face 311 between spacing, so as to be adapted with various sizes of fastener, without carrying a variety of differences
The spanner of specification, significantly reduces the carrying weight bearing of staff, and reduces the cost of purchase spanner, easy-to-use, easily
In carrying.
Preferably, in some alternative embodiments, the both ends of positioning region 31 pass through flexible piece and are connected with first assembly 1
Connect, therefore, without using the utility model proposes box spanner when, the shape of adjustable third component 3, thus reduce account for
Space facilitates staff to carry.
Preferably, in some alternative embodiments, Fig. 2 is that another box spanner is being just in the utility model embodiment
View, Fig. 3 are the cross-sectional view of Fig. 2 middle sleeve spanner, and Fig. 3 illustrates the internal structure of first assembly in Fig. 2, and Fig. 4 is to cover in Fig. 2
The top view of barrel spanner, please refers to Fig. 2 to Fig. 4, and third component 3 is chain, and positioning region 31 is at least one chain link, and the of chain
One end segment 32 and the second end segment 33 are connected with first assembly 1 respectively, and the first end segment 32 and the second end segment 33 are located at chain
Both ends.Compared with prior art, the utility model use component of the chain as fixation fastener, can for chain reserve compared with
Long size moves closer to the mistake of fastener in first end 211 this ensures that different size of fastener can be socketed
The shape of Cheng Zhong, chain change correspondingly, and chain is integrally gradually tightly attached to above fastener, tighten with rear chain and fix fastening
Part, because of the bendability characteristics of chain, the utility model proposes sleeve can be adapted with fastener of different shapes,
And chain has the characteristic that is connected successively, so can be effectively prevented chain when rotating fastener with box spanner
In the slippery surface of fastener.
Preferably, in some alternative embodiments, the second component 2 is telescopically disposed in relative to third component 3
On one component.In the present embodiment, scalable component is set by the second component 2, it can be using the structure of similar antenna, when need
