Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of torsion screwing tool.
Background technology
In the civil engineering process, need the reinforcing bar binding be lived by steel wire, and then carry out concrete casting.Usually, above-mentioned bundle steel wire operation is all finished by the operator is manual during civil engineering.
Obviously, manual its operating efficiency of steel wire of pricking is lower, and wastes time and energy in pricking the steel wire process.
Except civil engineering, in daily life at ordinary times, also often run into the situation generation that steel wire need be tied up, the operator reverses steel wire after adopting vice that steel wire is clamped again.But steel wire easily breaks away from actual mechanical process, uses to seem very not convenient, and simultaneously, operator's hand is near steel wire, and also easy hand to the operator damages in the process of tying up.
Summary of the invention
The purpose of this utility model is at the above-mentioned problem of existing in prior technology, provides a kind of binding efficient height in the tie wire process that makes, a kind of torsion screwing tool easy to use.
The purpose of this utility model can realize by following technical proposal: a kind of torsion screwing tool, it is characterized in that, this instrument comprises a tubular handle body and is shaft-like pull bar, pull bar the inner is positioned at the handle body, the pull bar outer end is stretched out the handle body and is provided with syndeton at its place, outer end, be with guide and spring on the described pull bar, the two ends of spring act on respectively on pull bar the inner and the guide, described guide is resisted against on the handle body under the elastic force effect of spring and is provided with the unidirectional mechanism that can make the guide one-directional rotation between handle body and guide, and the described pull bar outside has spiral helicine guide frame and above-mentioned guide is embedded in the guide frame place.
When adopting this torsion screwing tool tie wire etc., the syndeton place of pull bar is connected in the steel wire place.Spur the handle body then, pull bar can overcome the elastic force of spring in drawing process, and promptly pull bar stretches out the outer end of length of spring compressed back stay to handle is external.
When pull bar is protruding, under the effect of guide and guide frame, make pull bar to rotate with respect to guide.Simultaneously, though guide has a trend of just changeing, guide can not rotate under the effect of unidirectional mechanism.Obviously, so just make and to rotate with respect to the handle body in the outwardly directed process of pull bar.
After unclamping the handle body, at the elastic force effect lower link of the spring handle body of can withdrawing.Guide frame can promote the guide counter-rotating in this process, and guide can reverse with respect to cylindrical shell under the effect of unidirectional mechanism simultaneously.That is to say that pull bar can not rotate in the withdrawal process.
Reciprocal pulling handle body just can make the continuous rotation that pull bar can only be unidirectional in reciprocal telescopic process.Obviously, the steel wire that is connected in syndeton place, pull bar outer end will be banded in together.Certainly, except steel wire, also other ropy can be banded together.
In above-mentioned torsion screwing tool, described guide frame is the spiral helicine groove in the pull bar outside.Such structure makes guide to rotate along groove, and when guide can not rotate, pull bar will rotate.
As another scheme, in above-mentioned torsion screwing tool, described guide frame is the spiral helicine guide rail in the pull bar outside.Such structure makes guide to rotate along groove equally, and when guide can not rotate, pull bar will rotate.
In above-mentioned torsion screwing tool, described guide is tubular and its inboard has the convex edge that is complementary with above-mentioned guide frame, and the convex edge that guide is enclosed within on the pull bar and on the guide is positioned at the guide frame place.The convex edge is embedded in the guide frame place just can make pull bar rotate with respect to guide, or guide is rotated with respect to pull bar.
In above-mentioned torsion screwing tool, described groove is 1-4, and described guide inboard has the convex edge identical with groove quantity.Make sliding that guide can be more stable by such structure along groove.
In above-mentioned torsion screwing tool, described unidirectional mechanism comprises the ratchet one and the ratchet of being located on the handle body two of guide end.Elastic force effect ratchet one at spring is meshed with ratchet two, so just makes the rotation that guide can only be unidirectional with respect to the handle body.
In above-mentioned torsion screwing tool, be with adapter sleeve on the described pull bar, adapter sleeve and handle body link by screw thread, and above-mentioned ratchet two is located on the adapter sleeve.Such structure makes this torsion screwing tool easy to loading and unloading.
In above-mentioned torsion screwing tool, described syndeton is to be located at the hook of pull bar outer end.Just can be by hook with connections easily such as steel wires.
Compared with prior art, the connecting portion hanging support of this torsion screwing tool on only need be with it when tie wire etc. is on steel wire, and reciprocal then pulling handle body can be with steel wire around knot together.Therefore, it is easy to use, and is easy and simple to handle, laborsaving.
Simultaneously, this torsion screwing tool is difficult for hindering hand when tie wire, and safety is higher.And it only is made up of handle body, pull bar, guide and spring etc., and therefore, structure is also fairly simple.

The specific embodiment
As depicted in figs. 1 and 2, this torsion screwing tool is used to tie up ropies such as iron wire, and it is made up of handle body 1, pull bar 2, guide 4 and spring 3 etc.
By the adapter sleeve 9 that has been threaded, adapter sleeve 9 is enclosed within on the pull bar 2 in the port of handle body 1.Also be with a tubular guide 4 on the pull bar 2, also be with a spring 3 on pull bar 2, the two ends difference roof pressure of spring 3 is on pull bar 2 the inners and guide 4, and guide 4 is resisted against on the adapter sleeve 9 under the elastic force effect of spring 3.
As shown in Figure 3 and Figure 4, the end of guide 4 has ratchet 1, and the end of adapter sleeve 9 has ratchet 28, and is meshed with ratchet 28 on the adapter sleeve 9 at the ratchet 1 of guide 4 under the elastic force effect of spring 3.
As Fig. 3 and Fig. 4 and shown in Figure 5, have spiral helicine groove 5 in the outside of pull bar 2, above-mentioned guide 4 inboards have the convex edge 6 of protrusion, and convex edge 6 is complementary with groove 5, and convex edge 6 is embedded in groove 5 places.
As depicted in figs. 1 and 2, when in the civil engineering process, pricking the knot steel wire, steel wire is bundled on the reinforcing bar a little.Hook 10 hanging supports that make pull bar 2 outer ends then are on steel wire.Then spur handle body 1, it is overhanging with respect to handle body 1 that pull bar 2 overcomes the elastic force of spring 3.Unidirectional mechanism makes guide 4 to rotate in this process, and pull bar 2 rotates with respect to guide 4 simultaneously, and promptly pull bar 2 stretches out in the process and can rotate with respect to handle body 1.
After unclamping handle body 1, reset in elastic force effect lower link 2 withdrawal of spring 3.At this moment, under the effect of unidirectional mechanism, make guide 4 to rotate, that is to say that pull bar 2 can rotate with respect to handle body 1 and guide 4, promptly be equivalent to pull bar 2 and in withdrawal handle body 1 process, can not rotate with respect to handle body 1.
Reciprocal pulling handle body 1 just can make the pull bar 2 can only be along a continuous rotation that direction is unidirectional.So just can be under the prerequisite of not taking out this instrument directly together with wire binding.
