Abstract

The utility model discloses a clasper, with a support axes which is pivoted with a frame arranged on the one end of the spanner and a block axes arranged on the other end in a striding way. A groove is separately positioned between the frame and a soleplate for the tie-down strip to circle around the groove, the support axes and the block axes; wherein any of the support axes and the block axes or both is/are pivoted and covered with an outer lining to facilitate the tie-down strip, when the spanner drives the tie-down strip to block, corresponding block structure is arranged on the position where the spanner and the frame blocks the tie-down strip, which controls the positioning elements to be at the state of block frame, the fixation of the tie-down strip is labor-saving and the loosing of the strip is quick, so as to adjust the distance between the two ends of the strip for the purpose of being smooth of quickly loosing the strip.

Description

Fastener

Technical field

The utility model relates to a kind of fastener, promptly a kind of can be laborsaving and tighten or decontrol the location technology of the Binding fastener of the state of pulling and supporting fast.

Background technology

Early stage binding article technology is directly to utilize bundling belt for it, main earlier that the bundling belt two ends are approximately fixing, impose the lax part of the power of tightening then in bundling belt, mode of operation so, need experience or senior bundle worker can be easily for it, general personnel can't operate really smoothly, and article are also non-very firm after binding, and bundling belt also seems mixed and disorderly in appearance in addition.

So just the someone develops " hand controller ", these structures are mainly tightened bundling belt with the ratchet capstan winch, yet, its in practical operation, but have bundling belt easily strand tightly in rotating shaft be difficult for untiing, and the first-class shortcoming of the congested rotating shaft of bundling belt, be difficult in the operation execute smoothly into, trace it to its cause, be be that bundling belt must constantly be wound on the rotating shaft due to, moreover its structure complexity of these hand controllers is higher, its acquisition cost can not significantly stimulate to the market demand naturally.

In view of this, this creator develops the TaiWan, China patent announcement M258929 number " buckle structure (one) ", M258930 number " buckle structure (two) ", M258931 number " buckle structure (three) ", M258932 number " buckle structure (four) ", M258933 number " buckle structure (five) ", M259760 number " buckle structure (six) ", case is improved before the M272636 number patents such as " buckle structure (seven) ", these structures are put on display abroad and are well received by the public, business opportunity is unlimited, the creator is not with this complacency, the still research and development of Chi Xuing, case in the use before finding these patents, it still can not reach laborsaving and QA best requirement fully, trace it to its cause, in fact be the friction of bundling belt and each axis excessive due to, improved so just create the utility model.

The utility model content

The purpose of this utility model be to provide a kind of can more laborsaving operation, and the fastener of tightening or discharge bundling belt fast.

For achieving the above object, technical solution of the present utility model is: a kind of fastener, and it comprises a framework, a plate moving part and two bundling belts; This framework has a base plate, is provided with side plate in these base plate both sides, and this base plate is provided with wears groove, and an end and a fixing bundling belt are fixed, and other holds then biside plate to be provided with fulcrum wearing to stride above the groove, wears pivot one length-adjustable bundling belt; And this pulling piece and framework winding, this pulling piece is provided with an axis striding with the corresponding position of fulcrum, and this axis is that pulling piece institute interlock is swung; One of them bundling belt of this two bundling belt is a regular length, another bundling belt then is an adjustable length, it is after wearing groove by the framework base plate, just circle constitutes the section of tightening around axis after supporting fulcrum, continue it, pass fulcrum after below the pile warp axis and tighten intersegmental pulling out and constitute and adjust section, when the axis of pulling piece under swing control, can be with this another bundling belt fastening or release; One of this axis or fulcrum are worn pivot one external bushing, make this external bushing freely rotate in axis or fulcrum periphery.

Described axis and fulcrum are all worn pivot external bushing.

After adopting such scheme, because the utility model is arbitrary or overlap pivot simultaneously one external bushing is arranged at fulcrum, the axis of existing buckle structure, to reach intermediary's bundling belt, making the fastening of bundling belt or discharge can be more smooth and easy, thereby operation more effortlessly, and tighten fast or discharge bundling belt.
