Description

Spanner

Technical field

The utility model relates to hardware & tools, relates in particular to a kind of spanner.

Background technology

In the car inspection and repair process, manual mode is generally adopted in the installation of bolt.Referring to Fig. 1; The example that is installed as with floor on the vehicle and wooden frame: wooden frame 1 is provided with first bolt hole 11; Correspondence is provided with second bolt hole 21 on the floor 2; Place plain washer 3 and turn 4 then, use bolt 7 to pass plain washer 3, turn 4, first bolt hole 11 and second bolt hole 21 at last, to realize fixing between wooden frame 1 and the floor 2.First bolt hole 11 is arranged in counterbore 8.

In the actual installation process, because the size of counterbore is less on the wooden frame, manual space is very little, and staff is difficult to extend into rotating bolt in the counterbore, and promptly the B among Fig. 1 is regional, so use manual mode to be difficult to construction bolt.

The utility model content

The utility model provides a kind of spanner, is used for optimizing the installation of counterbore bolt, increases work efficiency.

The utility model provides a kind of spanner, wherein, comprises

Handle, an end is provided with through hole;

Sleeve, two ends are opening, are fixed on the said through hole, and are communicated with said through hole, and said sleeve is used for ccontaining bolt to be installed and said bolt to be installed is applied moment of torsion.

Aforesaid spanner, preferably, the shape of cross section of the endoporus of said sleeve is regular hexagon.

Aforesaid spanner, preferably,

Said handle is bent to form orthogonal force section and connecting portion, and said through hole is opened in the end of said connecting portion away from said force section.

Aforesaid spanner, preferably,

Said sleeve is positioned at said connecting portion on the side of said force section.

Aforesaid spanner, preferably, said force section and connecting portion all are elongated rod shape.

Aforesaid spanner, preferably, the axis direction of said sleeve is parallel with the axis direction of said connecting portion.

The spanner that the utility model provides, its sleeve cooperates with bolt, and bolt is applied moment of torsion, in the use, as long as sleeve can extend in the counterbore, gets final product construction bolt, and it is very convenient to use, and has reduced the labour intensity of manual installation, has improved operating efficiency.

The specific embodiment

The spanner structure sketch map that Fig. 2 provides for the utility model embodiment, Fig. 3 are the right view of Fig. 2.

Referring to Fig. 2 and Fig. 3, the utility model provides a kind of spanner, and it comprises handle 5 and sleeve 6.Handle 5 one ends are provided with through hole (scheming not shown); Sleeve 6 two ends are opening, are fixed on the through hole, and are communicated with through hole, and sleeve 6 is used for ccontaining bolt to be installed and said bolt to be installed is applied moment of torsion, particularly, are that the bolt head of treating construction bolt applies moment of torsion.

During use, earlier bolt, plain washer and turn all are placed in the sleeve, then with bolt through in the bolt hole to be installed, swing handle is so that sleeve applies moment of torsion to bolt.In the use; As long as the size that sleeve rationally is set can realize the installation of small space inner bolt, is example with situation shown in Figure 1 still here, if the counter bore hole diameters in B zone is than the big 6mm-10mm of diameter of bolt head; The B zone that this moment, staff was difficult to reach; But the spanner that is to use present embodiment to provide, the size of sleeve can so just can realize the installation of bolt very easily only than the big 5mm-8mm of size of bolt head.

Referring to Fig. 3, further, the shape of cross section of the endoporus of sleeve 6 is regular hexagon.In the practical application, the applied range of hex bolts is arranged to above-mentioned shape with the endoporus of sleeve, makes spanner go for the installation of most of bolt in the maintenance process, the especially installation of connecting bolt between floor and the wooden frame.

Referring to Fig. 2, for application of force convenience, orthogonal force section 51 of handle 5 bent formation and connecting portion 52, through hole is opened in the end of connecting portion 52 away from force section 51.

Sleeve can be installed on the inwall of through hole, or is fixed on the end face of through hole, and here preferably, sleeve 6 is positioned at connecting portion 52 on the side of force section 51.So be provided with, can simplify the processing and manufacturing process, and not influence the performance of spanner.

For ease of making and alleviating hand-held weight, particularly, force section 51 all is elongated rod shape with connecting portion 52.These shape selections are convenient, make simple.

For the ease of to the spanner application of force, the axis direction of sleeve 6 can be parallel with the axis direction of connecting portion 52.

The spanner that the utility model embodiment provides, design ingenious, compact conformation, practical, can realize the installation of bolt, alleviated operator's labour intensity, increase work efficiency again.Practice shows that the bolt that uses manual mode to install in the counterbore shown in Figure 1 probably needs 10 minutes, and the spanner installation of using the utility model to provide only needs general 3 minutes, and fitting operation is time saving and energy saving.

What should explain at last is: above each embodiment is only in order to the technical scheme of explanation the utility model, but not to its restriction; Although the utility model has been carried out detailed explanation with reference to aforementioned each embodiment; Those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, perhaps to wherein part or all technical characteristic are equal to replacement; And these are revised or replacement, do not make the scope of each embodiment technical scheme of essence disengaging the utility model of relevant art scheme.
