Abstract

The invention relates to a binding and tying piece used for binding and tying articles. The piece is flexible and has slight elasticity after flexure. At least two groups of ratchet groups are coessentially formed on the surface of a horizontal timber-shaped body of the binding and typing piece and distribute on the strip-shaped bodies of both sides spaced by a border block, wherein at least one strip-shaped body is arranged on each side, and the ratchet groups of each strip-shaped body consist of at least two ratchets. When the effects of binding and tying are generated, the binding and tying piece can be divided into two parts, wherein the first part is an enclosing part for enclosing a binding and tying article, and the second part is an extending part extending out of the enclosing part; the extending part is redivided into at least two branch parts, and clamping toothed surfaces of the ratchets tensioned and clamped corresponding to the enclosing part on each branch part face towards the enclosing part and form meshing effects of the ratchets with check pawls served by a part of the enclosing part so as to generate binding, tying and checking effects. The binding and tying piece is convenient to operate and can achieve tightly binding and tying effects, relieve the binding and tying effects at any time, adjust the binding and tying compactness and be suitable for different binding and tying ranges.

Description

Binding and tying piece

[technical field]

The present invention refers to especially that relevant for a kind of binding and tying piece a kind of from the teeth outwards consubstantiality forms the above ratchet group of at least two groups, can be allocated on two strip shape bodies of being done to separate by boundary's piece, and the ratchet group of every strip shape body is made of at least two ratchets; When being used for the action of halved tie bolt thing work bundle bolt, can form one around firmly restrainting centering on part and stretching out this around the extended portion of part of bolt thing, this extended portion can be split up into two branches, each branch corresponding with should around the clamping flank of tooth of the ratchet of the urgent clamping of part all can with formed ratchet by this detent that serves as around part eat cooperation usefulness, reach the effect that causes tight bundle bolt and capable of regulating bundle bolt elasticity.

[background technology]

The known binding and tying piece that is used for restrainting bolt sack (for example: the sack bundle will be tacked after the holding food) is take bungee as the most frequently used.The stereo appearance figure of known binding and tying piece 1 as shown in Figure 1, it is to make moulding by the soft rubber material, it is common becoming at ordinary times round; The operation of its bundle bolt mode is shown in Fig. 2,3, by itself elastic reaction and be drawn into first and close up shape, be looped around again the sack place of sack 2, then with wear mode make the one end pass the surface, opposite end around ring body, the end tension that to stretch out at last, sack 2 is tightly restrainted by this binding and tying piece 1 tacked, believe that this is the experience of life that common people all have.

When shown in Fig. 2,3, binding and tying piece 1 bundle tacked bundle bolt thing and tension after, this binding and tying piece 1 can be distinguished into two parts, first centers on part 11 around what live this bundle bolt thing, it comprises a termination 111; Then for stretching out the extended portion 12 outside this termination that centers on part 11 111, this extended portion 12 can be divided into two branches 121,122 again to second portion significantly.Around part 11, termination 111, extended portion 12, and branch 121,122 to define be to comply with the different active positions that present and define under the state that uses at random; When reverting to round binding and tying piece 1 shown in Figure 1 when using status releasing, where is namely can't distinguish thereon around part 11 and termination 111? where is extended portion 12 and branch 121,122? but when using once again, then at once can distinguish again around part 11, termination 111 extended portion 12 and branch 121,122.

Though known binding and tying piece 1 has existed for a long time and be widely used by popular, but in fact exist in actual use sizable disappearance, namely has elasticity because of binding and tying piece 1, and surfacing is without any non-return position, so binding and tying piece 1 has slowly naturally to back out because of its elasticity and causes relaxing possible (as shown in Figure 4) that gets loose when using, if comparison diagram 3,4 state, can find out that original extended portion 12 length in Fig. 3 are more, but in Fig. 4, because the back segment of extended portion 12 is return in this termination 111 gradually, and become around the part of part 11, fluff so this extended portion 12 shortens and center on part 11, causing sack 2 gradually to be can't be by the state in bolt jail tightly, so affect easily the normality of sack 2 interior foods, or the object of sack 2 is dropped out easily, this is the known binding and tying piece 1 textural serious disappearance that can't overcome own.So general people prevents from occuring such as the expressed bundle bolt of Fig. 4 phenomenon that gets loose, when the bundle bolt of being everlasting is finished, smoothly again extended portion more than 12 is beaten several knots, make bundle bolt place relatively be difficult to throw off, only derive so again when wanting to untie in the future, must the more strength of cost, even must take to cut off or the powerful failure mode of pulling apart is untied, so not only inconvenient, and also cause again repeated usage of binding and tying piece.

Except the above-mentioned person that is commonly called as the bungee, the binding and tying piece that generally is used for restrainting the bolt sack adopts the usual gimmick of plastic ties in addition.Be plastic ties to be cut into a bit of in early days, when being used for restrainting bolt, namely get a bit of use.Its operation can only be made a call to a knot take direct knotting as main if also want to untie then, if do not think to untie again or must closely restraint bolt, then just beats most individual knots.Even if its disappearance is only to make a call to a knot, if slip-knot also has the possibility of unclamping gradually; If fast knot then has the trouble that is difficult to untie equally; If beat most knots, that can only be to cut off the means of restrainting bolt as removing, so it uses the same difficult ideal that claims.Then having afterwards manufacturer that plastic ties is manufactured one encloses, with the time carry out to be same as with the noose gimmick of bungee and restraint bolt, precisely because have degree of tightening not good (poor than bungee), automatically slowly back out sometimes (reason of the plastic ties tool tension force of tightening), and the disappearance that (referring to beat most knots) is difficult to untie during bundle bolt tension, be all in the use and denounce.So under the situation that occurs without better binding and tying piece, at present still take the plastic ties of using bungee and lopping as common.

No matter be bungee or plastic ties, though its real surface is not really fully smooth under micro-, but under the use state, because being pulled or being subjected to this to center on the effect of part 11 tension force, so that this extended portion 12 can be continuously by or return this termination 111 (shown in Fig. 3,4), there is no the effect that is subject to any non-return; Therefore objectively can be considered as continuity when the state of use smooth for the body surface of known binding and tying piece, and this is the structure common ground in the use of known binding and tying piece.

[summary of the invention]

Purpose of the present invention namely is to provide a kind of binding and tying piece, with handled easily bundle bolt action and reach tight bundle bolt effect, and can make things convenient for again at any time operation to remove the bolt effect of restrainting.

Another object of the present invention is to provide a kind of binding and tying piece, when being used for the action of operation bundle bolt, can adjust bundle bolt elasticity, uses to adapt to different bundle bolt scopes.

A kind of binding and tying piece of the present invention, it is formed in one, in order to restraint the bolt article, binding and tying piece becomes that consubstantiality forms the above ratchet group of at least two groups on the surface of horizontal wire rod shape body, be allocated in by boundary's piece and do two limits separate and every limit at least on each strip shape body, the ratchet group of every strip shape body is made of at least two ratchets; Can be divided into two parts when being used for bundle bolt article, first is for centering on the part that centers on of firmly restrainting the bolt thing, and second portion is to stretch out this around the extended portion of part; This extended portion is separated at least two branches again, in each branch with should be around the clamping flank of tooth of the ratchet of the corresponding urgent clamping of part all towards around part, so namely with by this eat cooperation usefulness around what detent of serving as of part formed ratchet, to prevent this extended portion retraction.

Wherein, this binding and tying piece may be molded to round.

Wherein, when this binding and tying piece is shaped to round, by boundary's piece do two limits separate and every limit at least each strip shape body can connect with boundary's piece, and make when doing two limits separate and every limit each strip shape body closes up at least by boundary's piece from boundary's piece application of force, by boundary's piece do two limits separate and every limit at least on each strip shape body the arrangement mode of the ratchet of each ratchet group be: the clamping flank of tooth of the ratchet of same ratchet group can be towards same boundary piece on each strip shape body, and make the clamping flank of tooth of ratchet that two limits that separate and every limit be positioned at the ratchet group of homonymy at least on each strip shape body by boundary's piece can be towards same boundary piece.

Wherein, this binding and tying piece may be molded to strip.

Wherein, when this binding and tying piece is shaped to strip, by boundary's piece do two limits separate and every limit at least on each strip shape body the arrangement mode of the ratchet of each ratchet group be: the clamping flank of tooth of the ratchet of each ratchet group is all towards same boundary piece on each strip shape body, and this boundary's piece is positioned at adjacent of the ratchet group of different edge strip shape body.

Wherein, this binding and tying piece around firmly restraint the bolt thing on part, be detent for the part of the urgent clamping of the clamping flank of tooth of ratchet corresponding in extended portion at least two branches, and it is constant to serve as the function of detent behind this detent turn-knob unspecified angle.

Wherein, binding and tying piece becomes the line of centers of horizontal wire rod shape body and the angle of the ratchet flank of tooth, and one is≤90 °, and another one is＞90.

A kind of binding and tying piece of the present invention, its advantage and effect are: this binding and tying piece handled easily bundle bolt action, can reach tight bundle bolt effect, and again convenient at any time releasing bundle bolt effect.Simultaneously, when being used for the action of operation bundle bolt, can adjust bundle bolt elasticity, use to adapt to different bundle bolt scopes.

[specific embodiment]

Below in conjunction with accompanying drawing, technical scheme of the present invention is described further.

See also shown in Figure 5, the binding and tying piece 3 of first embodiment of the invention is formed in one and is round (the circular square or any shape of round possibility), it is better to make it have elasticity with the soft rubber making, but do not get rid of yet can other material or composite material make, for example: make moulding with fiber, resin material or nonwoven cloth material; Perhaps, by providing flexibility take metal material as main composite material manufacturing, and the binding and tying piece of the little ability of rebounding of tool all can.Binding and tying piece 3 mainly is that the lateral surface at body has into the arrangement shape and is evident as the

ratchet group

31,32 of different groups; Wherein,

ratchet group

31,32 respectively includes most and becomes continuously arranged ratchets 311,321, and ratchet group 31 is separation with the difform boundary of ratchet piece 33 obviously by one all with 32 adjacent; After this binding and tying piece 3 is made moulding, do not apply under the situation of any external force independent the storing, as shown in Figure 5 self-assembling formation round kenel; Obviously can find out this moment, ratchet group 31 existing bodies are a strip shape body, ratchet group 32 existing bodies then are another strip shape body, two strip shape bodies are obviously connected and are separated by two boundary's pieces 33, in other words, two strip shape bodies are that being positioned at by arbitrary boundary piece 33 is on two limits that separate, and on two limits that separate a strip shape body are arranged at least respectively by arbitrary boundary piece 33; If therefore with hand-held take this two boundaries piece 33 and a little the application of force draw outward the strip shape body on two limits closed up, then whole binding and tying piece 3 can form the kenel of closing up as shown in Figure 6, then recovers again round kenel as shown in Figure 5 during relinquishment.

Be defined as follows for giving first about some parameters of ratchet in this specification sheets, if with ratchet group 31 among Fig. 6, arbitrary segment of 32 is amplified namely as shown in Figure 7, wherein, the body of the horizontal wire rod shape of one-tenth is MB on the binding and tying piece 3, this body line of centers is BL, then take line of centers BL as benchmark, each ratchet 311,321 all have the larger clamping flank of tooth TF1 of a gradient and the less smooth flank of tooth TF2 of a gradient, and the included angle A N1 between line of centers BL and the clamping flank of tooth TF1 is necessary for≤90 ° (acute angle or right angle), and the included angle A N2 between line of centers BL and the smooth flank of tooth TF2 is ° (obtuse angle) then＞90; This clamping flank of tooth TF1 can be effectively with carry out the clamping effect by the detent that serves as around part, so be referred to as " the clamping flank of tooth ", smooth flank of tooth TF2 then does the time spent and can allow the smooth position of passing through of binding and tying piece for tightening, so be referred to as " the smooth flank of tooth ".

When binding and tying piece 3 is biased the aspect that pulls into as shown in Figure 6, if take arbitrary boundary piece 33 as the termination, can find out that juxtaposed

ratchet group

31 and 32 is present in by boundary's piece 33 separately for becoming the kenel of row's ratchet on the two limit strip shape bodies that separate, and the clamping flank of tooth TF1 on the

ratchet group

31,32 ratchet 311,321 is all towards same boundary piece 33.Using binding and tying piece 3 namely to pull into first the kenel of closing up shown in Figure 6 is used for halved tie bolt thing again and restraints the bolt operation, boundary's piece 33 of taking two ends is held respectively by its operating mode system with two hands, adopt again the wear gimmick identical with the known bungee of present use, improve left margin piece 33 (with directions shown in Figure 6), make the revolution of up turning right again go to wear and also reverse a little strip shape body under right margin piece 33 inboards in the formed ring body, make on the

ratchet group

31,32 and face this ring body corresponding to the ratchet 311 of this ring body, 321 clamping flank of tooth TF1, tension gets final product again.

Binding and tying piece 3 is finished after the bundle bolt operation namely as shown in Figure 8, and the binding and tying piece 3 that is in bundle bolt (tension) state can be divided into two parts, first for around firmly restraint the bolt thing around part A, have boundary's piece 33 namely to form the end A 1 that this centers on part A; Second portion is then for stretching out this around the extended portion B of the end A 1 of part A; This extended portion B obviously is separated into again two B1 of branch, B2, and take another boundary's piece 33 as the boundary, wherein, includes separately some ratchets 311,321 of

ratchet group

31 or 32 on the B1 of branch, the B2; And all the other ratchets 311,321 that do not belong to extended portion B namely become this around body or the part of part A; The the most long-range of two B1 of branch, B2 that this extended portion B separates namely connecting with boundary's piece 33; And belong in the

ratchet group

31,32 extended portion B ratchet 311,321 clamping flank of tooth TF1 can be towards this around part A end A 1 (i.e. boundary's piece 33), so this end A 1 namely forms on the

confession ratchet group

31,32 detent that the ratchet 311 corresponding with end A 1,321 clamping flank of tooth TF1 are done the effect of urgent clamping non-return.Strict, with card contact that corresponding ratchet 311,321 is made urgent clamping non-return two places are arranged on the end A 1, and this two places card contact can change a little because of the tightness of bundle bolt, and meaning namely serves as the detent, and the person is not attachment point, but variable area division; The effect of the urgent clamping non-return of this kind can be done unidirectional urging tightly, because urging tight when action is in the face of end A 1 by each ratchet 311,321 smooth flank of tooth TF2, and smooth flank of tooth TF2 can't with end A 1 clamping, so each smooth flank of tooth TF2 all can be easy to by end A 1 under pulling function, to reach the unidirectional effect of urging tightly and urging tighter and tighter; Even and if let go when arriving any tightness, also necessarily have one group of corresponding ratchet 311,321 and guarantee the effect of tightening by its clamping flank of tooth TF1 with serving as the end A 1 rapid clamping non-return of detent, certainly elasticity can change with the end A 1 corresponding ratchet 311,321 of doing clamping not simultaneously.

Adopt the material moulding that to rebound after the deflection because of binding and tying piece 3, arbitrarily turn-knob rotation on using, and each

ratchet group

31,32 are all by at least two ratchets 311,321 consist of the aspect of row's ratchet, so when doing the action of bundle bolt, because having pulling this extended portion B wish retraction (returning), the tight tension force that produces is somebody's turn to do the interior tendency around part A around the part A that centers on that firmly restraints the bolt thing, but two B1 of branch because of this extended portion B, the upper corresponding ratchet 311 of B2,321 clamping flank of tooth TF1 is all blocked and can't retract (returning) by the detent that is served as by end A 1 (namely centering on the part of part A), and because the smooth flank of tooth TF2 around part A passes through end A 1 easily, and namely instead can't be return by clamping by clamping flank of tooth TF1 by rear, so can unidirectional urge tighter and tighter, and reach the effect of bundle bolt.And wish is removed the effect of bundle bolt, then only need pulling (shaking) place of tightening to serve as the position of detent (may be boundary's piece 33 or a part that centers on part A), make the ratchet 311 of this position of serving as detent and corresponding clamping, 321 clamping non-return effect is loosening and throw off, then the effect of originally restrainting bolt can be untied fully.

What obviously can serve as the detent effect must not be boundary's piece 33, as long as bundle bolt back is to ratchet corresponding on the

ratchet group

31,32 311,321 clamping flank of tooth TF1, and detent all can be served as in the position that can produce the effect of clamping non-return, vertical is also can in this part that centers on position A, meaning namely serves as the detent, and the person can be an area division, but not attachment point.Moreover, detent is not that fixed angle just can serve as yet, because binding and tying piece 3 is made moulding for the deflection material, so in operating process, after part A turn-knob angle, restraint again the bolt action, also necessarily have a partial face to the upper corresponding ratchet 311 of two B1 of branch, the B2 of projection position B, 321 clamping flank of tooth TF1, and this part is and serves as detent.In other words, so long as can be detent to the part that the upper corresponding ratchet 311 of two B1 of branch, the B2 of projection position B, 321 clamping flank of tooth TF1 carry out the non-return effect.

The binding and tying piece 3 that is shaped to the round aspect shown in Figure 5 can have many variations, and all includes in claim of the present invention, for example can be varied to the variation example shown in Fig. 9 to 13.Fig. 9 has into continuous arrangement and is evident as the ratchet group of different groups at body, is respectively the ratchet group 34,34 ' and the ratchet group 35,35 ' of the body downside that coexists of the body upside that coexists; Wherein, the ratchet group 34 of the body upside that coexists (namely at homonymy), 34 ' adjacent all by one obviously with the difform boundary of ratchet piece 33 for separating, and every group of ratchet group 34,34 ' has the continuously arranged ratchet 341,341 ' of most one-tenth; Coexist body downside (also for homonymy) ratchet group 35,35 ' then equally by obviously with the difform boundary of ratchet piece 33 for separating, and every group of ratchet group 35,35 ' has the continuously arranged ratchet 351,351 ' of most one-tenth; The binding and tying piece 3 of Fig. 9 does not apply under the situation of any external force independent the storing, meeting self-assembling formation round kenel; Can obviously find out that

ratchet group

34,35 existing bodies are a strip shape body this moment, and ratchet group 34 ', the 35 ' existing body then are another strip shape body, and two strip shape bodies are obviously connected and separated by two boundary's pieces 33.

With hand-held take this two boundaries piece 33 and a little the application of force draw outward when two strip shape bodies are closed up, whole binding and tying piece 3 can form kenel as shown in figure 10, this moment is take arbitrary boundary piece 33 as the termination, can find out coexist upside and adjacent ratchet group 34 and the structure aspect of the 34 ' row's of being all ratchet, be present in separately on the two limit strip shape bodies of being separated by boundary's piece 33, and the ratchet on ratchet group 34 and 34 ' 341,341 ' is arranged for equidirectional, and its clamping flank of tooth TF1 can be towards same boundary piece 33; Similarly, can find out the also structure aspect of the row's of being all ratchet of downside and adjacent ratchet group 35,35 ' that coexists, be present in separately on the two limit strip shape bodies of being separated by boundary's piece 33, and ratchet group 35,35 ' ratchet 351,351 ' are that equidirectional is arranged, and its clamping flank of tooth TF1 can be towards another boundary's piece 33; And the ratchet group 34 of dividing a upper and lower sides (namely not homonymy) with strip shape body and 35 ratchet 341,351 orientation can be different, and towards different boundaries piece 33; Similarly, the ratchet group 34 ' of dividing a upper and lower sides (namely not homonymy) with strip shape body and 35 ' ratchet 341 ', 351 ' orientation can be different, and towards different boundaries piece 33.

Figure 11 is the ratchet group 34,34 ' (its clamping flank of tooth TF1 is towards same boundary piece 33 after stretching) that keeps the upside that coexists, and downside is not then established the ratchet group; Figure 12 then keeps the ratchet group 35,35 ' (its clamping flank of tooth TF1 is towards same boundary piece 33 after stretching) of the downside that coexists, but upside is not then established the ratchet group; Figure 13 then is into the ratchet group 36,36 ' that has into the arrangement shape on the medial surface of binding and tying piece 3 of round kenel and be evident as different groups, include separately most and become continuously arranged ratchets 361,361 ', and equally by obviously with the difform boundary of ratchet piece 33 for being connected and separating; Figure 13 shows originally becoming the binding and tying piece 3 of round kenel to draw outside two boundary's pieces, 33 application of forces, makes two strip shape bodies close up the state that is close to together with ratchet group 36,36 '; Because of two ratchet groups 36,36 ' all on the inner surface of binding and tying piece 3, and its ratchet 361,361 ' clamping flank of tooth TF1 towards same boundary piece 33, identical with that shown in Figure 6 when therefore being used for bundle bolt article, as long as reverse a little two branches of extended portion, make its ratchet 361,361 ' and connect, and clamping flank of tooth TF1 is towards around part, namely can reach equally the bundle bolt effect of making mutual clamping non-return by ratchet 361,361 ' clamping flank of tooth TF1 and detent.Hence one can see that, accessible effect and shown in Figure 5 identical when four kinds of variation examples that Fig. 9 to 13 lifts are used for bundle bolt article.

If the most long-range boundary's piece 33 of extended portion B among Fig. 8 is cut off, then namely form two B1 of branch shown in Figure 14, B2 in the long-range state that does not connect.By as can be known its effect of tightening and Fig. 8 identical (effect of namely tightening does not change) shown in Figure 14, if but the state of tightening shown in Figure 14 is untied, then namely become the strip binding and tying piece 4 that Figure 15 shows that second embodiment of the invention, its equally by various materials separately or composite manufacturing, but and tool flexibility and spring-back properties after the moulding.There is boundary's piece 43 in the central authorities of binding and tying piece 4, two limits (different limit) respectively stretches out a strip shape body to the left and right again, then the homonymy at two limit strip shape bodies has the ratchet group 41,42 (the structure aspect of the row's of being all ratchet) that is separated out the different directions arrangement take boundary's piece 43 as watershed area, and respectively include most the ratchets 411,421 that become continuous shapes to arrange, and ratchet 411,421 clamping flank of tooth TF1 (its definition with as shown in Figure 7) are all towards same boundary piece 43.

Strip binding and tying piece 4 shown in Figure 15 can have two kinds of operating mode when being used for the bundle bolt, the first is from this boundary's piece 43 places bending with strip binding and tying piece 4, make two limit strip shape bodies draw close juxtaposition, then carry out the bundle bolt operating process identical with the first embodiment, namely finish bundle bolt state as shown in figure 14; The second is adopted the knotting mode with strip binding and tying piece 4 and is enwinded bundle bolt place and strained, and then namely finishes bundle bolt state as shown in figure 16.By as can be known shown in Figure 16, the binding and tying piece 4 that is in the effect of knotting bundle bolt can be divided into two parts, first for around firmly restraint the bolt thing around part A, (boundary's piece 43 belongs to around part A), second portion is then for stretching out this around the extended portion B of part A, this extended portion B obviously can be divided into two B1 of branch, B2, and two B1 of branch, B2 stretch out to different directions, and the B1 of this two branch, B2 divides out and without connection.

When tightening binding and tying piece 4, should be around part A because of the tight tension force that bears, and this binding and tying piece 4 is because of tool elasticity, so naturally can produce the strength of reinstatement, impel the B1 of this two branch, B2 all has one to bundle bolt object space to the strength of retracting, but the B1 of this two branch, respectively have on the B2 can be corresponding more than two ratchet 411,421, its clamping flank of tooth TF1 is all towards centering on part A, so B1 of this two branch, when B2 will retract, its corresponding ratchet 411,421 clamping flank of tooth TF1 can should be served as detent around the part of part A and be stopped, thereby reach the bundle bolt effect that causes, even and if with the passing of time also not unclamping voluntarily; If when straining again binding and tying piece 4 and more tightening, that face because of detent is the smooth flank of tooth TF2 (its definition with as shown in Figure 7) of ratchet, therefore vertical is that the junction that centers on part A also can allow the smooth flank of tooth TF2 of ratchet pass through along friction, so the upper corresponding ratchet 411,421 of making the clamping non-return of two B1 of branch, B2 can change, certainly its corresponding detent position also can be along with change, and has the action and efficacy of adjusting elasticity or degree of tightness scope; And when tightening action when stopping, because the clamping flank of tooth TF1 that detent becomes at once in the face of ratchet does urgent clamping, so bring into play at once the non-return effect.

Ratchet group 41 on two B1 of branch, the B2 of and the extended portion B upper around part A of this binding and tying

piece

4,42 ratchet 411,421 are done any part of corresponding contact all can serve as detent, and meaning namely serves as the detent, and the person can be an area division, but not attachment point.And because binding and tying piece 4 is for having flexibility, therefore when operation bundle bolt, may be sometimes can present various turn-knob phenomenons with part that corresponding ratchet 411,421 is done clamping, all can serve as detent but every place turn-knob is crossed the part of certain angle, produce the effect of ratchet 411,421 clamping non-returns of allowing.In other words, even if still have the effect of serving as detent after serving as the part turn-knob unspecified angle of detent.

When restrainting the dimensional variations of bolt thing, bundle bolt posterior cord is fastened the ratchet 411,421 and the change that also is bound to of the position of detent of corresponding clamping on the part 4, for example, originally belonged to ratchet 411 around the part of part A, 421 can because want Shu Shuangeng tight and along with two B1 of branch, B2 are pulled outwardly movingly, therefore become two B1 of branch, B2 is upper with reduce the scope after center on the ratchet 411,42 that part A does corresponding clamping; Or the ratchet 411,421 that originally belonged on two B1 of branch, the B2 can be because want Shu Shuancheng wider shape attitude (for example adding bundle bolt thing), and retract in the scope of part A along with being operated, therefore become the part around part A behind the expanded scope, still can finish smoothly the effect of bundle bolt along with bundle bolt thing range of sizes adjustment with convenient.Remove the bundle bolt effect of binding and tying piece 4 as for wish, then need only scratch moving corresponding ratchet 411,421 and detent clamping part to point, the bundle bolt effect that makes clamping non-return originally is pine and eventually to throwing off gradually, and the state that then will twine tubercle is opened and got final product, and is very convenient in the use.

The binding and tying piece 4 that is shaped to as shown in figure 15 the strip aspect also can be varied to the variation example shown in Figure 17,18, and wherein, Figure 17 is that the upper and lower sides at different limit strip shape body all is provided with

ratchet group

41,42,41,, 42 '; Figure 18 keeps to be positioned on the strip shape body of different limit the not ratchet group 41,42 ' (or 42,41 ') of homonymy (minute upper and lower side in position), and these two kinds change example and are used for shown in the operation of bundle bolt article and accessible effect and Figure 14 to 16 identical.

By above explanation as can be known, though binding and tying piece of the present invention as Fig. 5,6 and Fig. 9 to 13 shown in be shaped to round, or shown in Figure 15,17,18, be shaped to strip, the material that adopts with moulding after the tool flexibility, and the material of tool micro-elasticity all can after the deflection, constructional feature then becomes consubstantiality on the surface of horizontal wire rod shape body to form ratchet group more than at least two groups at binding and tying piece, be allocated in by boundary's piece and do two limits separate and every limit at least on each strip shape body, every group of ratchet group is made of at least two ratchets, in order to the elasticity of adjusting the bundle bolt; When the effect of bundle bolt produced, binding and tying piece can be divided into two parts, and first is for centering on the part that centers on of firmly restrainting the bolt thing, and second portion is to stretch out this around the extended portion of part; This extended portion can be divided at least two branches, and each branch all has with this around the corresponding ratchet of part, and its clamping flank of tooth is all towards around part; Binding and tying piece all can serve as corresponding ratchet in the detent of bundle during bolt around the part of part, and its to serve as the function of serving as detent behind the local turn-knob of detent still constant, with the effect of handled easily bundle bolt; And binding and tying piece becomes the line of centers of horizontal wire rod shape body and the angle of the ratchet flank of tooth, and one is≤90 ° (acute angle or right angles), and another one is＞90 ° (obtuse angles).
