According to the knowledge of the applicant, the bindiny mechanism of the crimp head of tubular type binding instrument is in the prior art: anvil pull rod is connected with the mode that annular groove matches by U-shaped rustless steel shell fragment with pin anvil shaft, that is: a side of link is a bullet hair style mandrel structure, have groove above, opposite side is that mandrel is put tubulature, symmetry is offered two bar holes on the tube wall, two U-shaped rustless steel shell fragments are inserted into round tube inner wall from bar hole, the end of shell fragment has projection, this projection matches with groove on the mandrel, plays the effect that plug-in flexibly connects.In this bindiny mechanism, the processing technique more complicated of U-shaped rustless steel shell fragment, qualification rate is low, and processing cost height, circulation time are long; During assembling U-shaped rustless steel shell fragment, tension can influence elasticity, pine can be caused and be skidded off excessively; And, when using, this connected mode easily produces lateral wobble, and fastness and feel are all undesirable.
Summary of the invention
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of rational in infrastructure, easy to use, crimp head bindiny mechanism that reliability is high is provided.
The purpose of this utility model realizes by following technical solution:
Crimp head bindiny mechanism comprises anvil pull rod and pin anvil shaft, and anvil pull rod links to each other with the Binding Instrument body part, and pin anvil shaft and pin anvil ring are fixed, and it is characterized in that: the link of anvil pull rod and pin anvil shaft, a side are the mandrel structure, are provided with annular groove above; An other side is that mandrel is put the tubulature structure, also be provided with annular groove on its tube wall, annular groove inside has through hole, other has one or more circular reeds that do not seal to be connected in the groove that has through hole along cross-directional, this reed inboard is provided with projection, its quantity, position are consistent with described through hole with size, and radially inwardly cross described through hole, match with the annular groove of mandrel structure link.
The purpose of this utility model also can further realize by following technical measures:
Aforesaid crimp head bindiny mechanism, wherein: described reed is single use, the both sides shape of the projection of reed is consistent with the fillet surface of the annular groove both sides of described mandrel structure link; Perhaps, described reed is a plurality of superimposed uses, and the side view of the projection of two outside reeds is consistent with the fillet surface of the annular groove of described mandrel structure link.
Further, aforesaid crimp head bindiny mechanism, wherein: the quantity of described through hole is more than 2 or 2.
Further, aforesaid any one crimp head bindiny mechanism, both can: the link of pin anvil shaft is the mandrel structure, and the link of anvil pull rod is that mandrel is put the tubulature structure; Again can: the link of anvil pull rod is the mandrel structure, puts the tubulature structure and the link of pin anvil shaft is a mandrel.
In addition, in the aforesaid crimp head bindiny mechanism, the outer surface of pin anvil shaft can also be provided with for circumferential localized guiding spline in anvil pull rod and the pin anvil shaft connection procedure, so as instrument in use nail-anvil assembly and nail bin groupware can be in place smoothly.
This utility model provides a kind of crimp head bindiny mechanism that is applicable to that the tubular type binding instrument uses, it puts the connected mode of tubulature as primitive form with mandrel and mandrel, by groove is set on mandrel is put tubulature, a plurality of through holes are set in the groove, be connected to mandrel with one or more reed that has projection then and put the tubulature surface, its projection sees through through hole and cooperates with the annular groove of mandrel, plays the effect that flexibly connects crimp head.This mode, anvil pull rod is more convenient, reliable with being connected of pin anvil shaft, and reed can the batch machining manufacturing, takes the circumstances into consideration as required during use to accept or reject; The installation of reed, the dismounting easier.Compared with prior art, reliability, the motility of instrument use all have further raising.
