Detailed description of the invention

Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.

Embodiment 1:

As shown in figs. 1-7, flexible self adaptation size inner hexagon spanner, it comprises handle 1, brace arm 2 and handle 1 rectangular, brace arm 2 inside is containing hexagon cavity 6, Compress Spring 4 is compressed in bottom hexagon cavity 6 by single-unit hollow hexagon socket head 3, and it is inner that single-unit hollow hexagon socket head 3 is enclosed in hexagon cavity 6 by internode briquetting 5.

As Fig. 3, described single-unit hollow hexagon socket head 3 inside is provided with second section Compress Spring 41, second section Compress Spring 41 is compressed in bottom second section hexagon cavity 61 by second section single-unit hollow hexagon socket head 31, it is inner that second section single-unit hollow hexagon socket head 31 is enclosed in second section hexagon cavity 61 by second section internode briquetting 51, and other respectively saves Compress Spring 4, single-unit hollow hexagon socket head 3 is identical with the installation method of second section with the installation method of internode briquetting 5.

Preferably, the quantity of described Compress Spring 4, single-unit hollow hexagon socket head 3 and internode briquetting 5 can be carried out selection according to actual needs and be installed, and each joint size also can be processed according to actual size.

As Fig. 4-5, described single-unit hollow hexagon socket head 3 comprises hexagon barrel 301 and cavity 302, and the end of hexagon barrel 301 is provided with lozenges 303.

As Fig. 6, described internode briquetting 5 comprises hexagonal boss 501 and coordinates cavity 502, the terminal surface of hexagonal boss 501 and hexagon cavity 6 matches, coordinate cavity 502 to match with single-unit hollow hexagon socket head 3, hexagonal boss 501 is processed with and coordinates lozenges 503 to match with lozenges 303.

As Fig. 7, be the course of work schematic diagram using this spanner to operate hexagon socket head cap screw 7.

Specific embodiment 2:

As Figure 1-3, a kind of flexible self adaptation size inner hexagon spanner, comprise and often save Compress Spring 4, different operating size single-unit hollow hexagon socket head 3, wherein minimum dimension 2.5mm is solid, the internode briquetting 5 of every internode.In the present embodiment, single-unit hollow hexagon socket head 3, Compress Spring 4 and internode briquetting 5 are six.

As illustrated in figures 4-5, working face hexagon barrel 301 shape of single-unit hollow hexagon socket head 3 is that hexagonal structure matches with hexagon socket head cap screw, hexagon cavity 6 is hexagonal structure, also have base to be also hexagonal structure, the bevel angle wherein connecting base and lozenges 303 is 30 ° as shown in Figure 4.

As shown in Figure 6, internode briquetting 5 comprises hexagonal boss 501 and coordinates cavity 502 to be all hexgonal structure, and internal engagement lozenges 503 is 30 °, matches with lozenges 303 angle of the single-unit hollow hexagon socket head 3 of reduced size.Adopt this kind of design, advantage is: 1 pressure thrust outside for a part of Compress Spring 4 being changed into internode briquetting 5 pairs of large-size single-unit hollow hexagon socket head 3 inwalls, increase frictional force, between design envoy in briquetting 5 bottom hexagonal outside diameter d 2 slightly larger than large-size single-unit hollow hexagon socket head 3 internal diameter D3, make that internode briquetting is more difficult to come off, enhance instrument durability; When 2 lozenges 303 to make in reduced size single-unit hollow hexagon socket head 3 retraction large-size in hexagonal, can eject smoothly, if right-angle structure, after there is retraction, block the situation that cannot eject.

Wherein, the single-unit hollow hexagon socket head of two adjacent sizes carries out nested combination, reduced size hollow hexagon socket head inserts in large-size hollow hexagon socket head, middle placement compressible spring, again internode briquetting is driven into hexagonal end in large-size hollow, the nested installation realizing two joint hexagon socket heads connects.

Wherein concrete installation fit dimension is: as Fig. 4-5, and large-size single-unit hollow hexagon socket head internal diameter D3 should slightly larger than reduced size single-unit hollow hexagon socket head base outer diameter D 1; Minimum length after reduced size single-unit hollow hexagon socket head length L1 adds spring-compressed should be less than or equal to the summation that large-size single-unit hollow hexagon socket head inner length L2 adds internode briquetting 5 top hexagonal boss 501 thickness H; In internode briquetting bottom, hexagonal outside diameter d 2 should slightly larger than hexagonal internal diameter D3 in large-size hollow, internode briquetting 5 top hexagonal boss 501 outside diameter d 1 should equal large-size single-unit hollow hexagon socket head outer diameter D 2, and internode briquetting 5 coordinates cavity 502 internal diameter d3 should slightly larger than reduced size single-unit hollow hexagon socket head outer diameter D 2.Spring diameter should be slightly less than large-size single-unit hollow hexagon socket head internal diameter D3.

Specific works process of the present utility model and operation principle are:

Adopt the work screwdriver bit of the inner hexagon spanner different size of this kind of nested structure can free-extension, when operating mode is the hexagon socket head cap screw of a certain size, after direct for instrument inserting bolt, the work screwdriver bit less than this Bolt sizes to automatically retract in upper strata in hexagonal, the work screwdriver bit energy joint bolt only having size to be applicable to, realizes the transmission of moment of torsion.

This patent, owing to have employed nested stretching structure, reduces instrument number, is convenient to storage, flexible operation in work, improves operating efficiency.Moreover decrease spanner number, save great deal of steel.

Above-described embodiment is used for explaining and the utility model is described; instead of the utility model is limited; in the protection domain of spirit of the present utility model and claim, to the novel any amendment made of this practical machine and change, all fall into protection domain of the present utility model.
