The internal screw thread of lattice and the stud 1 of dimension are threadedly engaged, so that silk braid 2 can be adapted for the stud of different size
1。
As shown in Figure 3 and Figure 4, in the present embodiment, stud combination wrench further includes convenient for the rotation of the rotation force of silk braid 2
Transfer part 11, rotating part 11 are wholely set with silk braid 2.Rotating part 11, which is convenient for rotating silk braid 2, to exert a force, convenient for by stud 1
First external screw thread 3 screw in the threaded hole 4 of silk braid 2 and stud 1 and the locking of 7 contact of mandril after by the of stud 1
Two external screw threads 14 screw in pilot hole.Rotating part 11 is wholely set with silk braid 2, i.e. a part that belongs to silk braid 2 of rotating part 11, just
It is manufactured in being integrally formed.Optionally, a part that the conduct of nut 8 rotating part 11, i.e. rotating part 11 belong to nut 8, nut 8 and silk
2 contacts are covered, rotating nuts 8 can drive silk braid 2 to rotate, and nut 8 is commercially available, does not need specially to process rotating part 11.
And by rotation loose nut 8 to discharge mandril 7, then silk braid 2 can be made to loosen from stud 1 by rotating silk braid 2.
As shown in Figure 3 and Figure 4, in the present embodiment, the shape of rotating part 11 is in triangular prism, quadrangular, pentagonal prism, hexagonal prisms
At least one of.Prism is convenient for applying torque to rotating part 11 from different directions, convenient for being used in narrow space, while
It is easily found corresponding force application means auxiliary force.As triangular prism, quadrangular, pentagonal prism, hexagonal prisms cooperate with corresponding spanner
It is convenient to turn rotating part 11.
As shown in figure 3, in the present embodiment, mandril 7 reduced when being equipped with the end face for contact stud 1 contact area with
Prevent the protrusion 12 of the end wear of stud 1.Protrusion 12 protrudes from the end face of mandril 7, protrusion 12 and double end spiral shell
The end face contact area of bolt 1 is small so that frictional force is small, can prevent the end wear of stud 1.
As shown in figure 3, in the present embodiment, the shape of protrusion 12 using in hemisphere, semiellipsoid, contour body at least
It is a kind of.Using spherical surface or the end face point contact of cambered surface and stud 1, contact area is small for hemisphere, semiellipsoid, contour body,
And can be avoided and stress concentration destruction is constituted to the end face of stud 1, the end wear of stud 1 can be better protected from.
As shown in Figure 3 and Figure 4, in the present embodiment, mandril 7 is equipped with to exert a force so that mandril 7 screws in applying in threaded hole 4
Power portion 13.Force section 13 exerts a force for manpower or mechanical grip, convenient for screwing in mandril 7 in threaded hole 4, avoids damage on mandril 7
Screw thread.
As shown in Figure 3 and Figure 4, in the present embodiment, force section 13 uses at least one of knob, mandril nut, handle.
Knob, mandril nut, handle can constitute wheel shaft structure with mandril 7, not only can be laborsaving, but can more accurately adjusting force it is big
It is small, prevent from exerting a force excessive mandril 7 and the locked damage screw thread of threaded hole 4 and 7 contact stud 1 of mandril damage stud 1
End face.
As shown in Figure 3 and Figure 4, in the present embodiment, the shape of silk braid 2 uses at least one of cylinder, stage body, sphere.
The manufacture easy to process of cylinder, stage body, sphere is also convenient for opening up threaded hole 4 inside it.
When it is implemented, providing a kind of stud combination wrench, the shape of silk braid 2 uses cylindrical body, the first internal screw thread 9
Specification it is different from the specification of the second internal screw thread 10, rotating part 11 is wholely set with silk braid 2, and the shape of rotating part 11 is in six ribs
Column, the shape of protrusion 12 use hemisphere, and force section 13 uses mandril nut.
The application method of the stud combination wrench is as follows:
Stud 1 is screwed in threaded hole 4 from the first end 5 of silk braid 2 first, the mandril 7 of nut 8 will be arranged with from silk braid
Until withstanding stud 1 in the 2 screw-in threaded hole 4 of second end 6, the nut 8 being arranged on mandril 7 is tightened and withstands silk braid 2, it
Stud 1 is assembled in pilot hole by twisting the rotating part 11 on silk braid 2 afterwards.After the assembly in place of stud 1, clamping
Rotating part 11 fixes silk braid 2, and nut 8 is unscrewed and is separated with silk braid 2, then mandril 7 is unscrewed and is separated with stud 1, finally
Opposite direction twists rotating part 11 and separates silk braid 2 with stud 1, completes assembly.
The length for only adjusting mandril 7 before assembly according to the length of stud 1, which fixes nut 8, can complete by the gross
The assembly of part, processing efficiency are obviously improved.Because of the end face for having mandril 7 to withstand stud 1, double end spiral shell is dismantled after having assembled
It not will drive the stud 1 assembled during bolt combination wrench, advantageously ensure that product quality.Stud combination
Spanner uses in production, has the characteristics that easily manufactured, the service life is high, easy to use and versatility is big.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
