The specific embodiment
See also shown in Fig. 1-5, the present invention relates to a kind of straight cuts stiching instrument that adopts novel jaw close mechanism, mainly comprise strap 1, nail supporting base assembly 2, closed clamping plate 3, drive mechanism and closed sleeve pipe 5.
Strap 1 front portion is equipped with nail bin groupware 11; The middle part is provided with forward and backward rotational pin 12,13; The rear end of nail supporting base assembly 2 is connected with preceding rotational pin 12, and the front end of closed clamping plate 3 is connected with back rotational pin 13, and can be separately installed with the torsion spring or the leaf spring of opposing strap 1 and nail supporting base assembly 2, closed clamping plate 3 closures; In the slot of the one section closed clamping plate of insertion 3 bottom surface of leaf spring, the other end is between percussion push rod and the closed clamping plate.Closed sleeve pipe 5 can be along strap 1 to the forward and backward rotational pin of being installed in of front slide 12, between 13, and the limited step 18 of the closed sleeve pipe 5 reach scopes of restriction can be set on strap 1.
Preferable; Also can be outside closed sleeve pipe 5 sheathed shell 51, shell 51 is fixedly connected with strap 1, between shell 51 inwalls and closed sleeve pipe 5 outer walls spring 52 is installed; When pushing ahead closed sleeve pipe 5; Need the elastic force of this spring 52 of opposing, like no external force effect, closed sleeve pipe 5 is return under the elastic force effect of spring 52 backward.
Further, also can on strap 1, jaw locking safety block 54 be installed through compression spring 53.Specifically; Can offer two grooves 14 in the bottom of strap 1, be fixed with two spring fixed blocks 15 with groove 14 corresponding tops, jaw locking safety block 54 is provided with two upwardly extending connecting portions; Jaw locking safety block 54 is installed in strap 1 below; Two connecting portions are in groove 14 stretches into strap 1, and the upper end of compression spring 53 is fixedly connected with spring fixed block 15, and the lower end is fixedly connected with the connecting portion of jaw locking safety block 54.
When closed sleeve pipe 5 was positioned at initial position, jaw locking safety block 54 was positioned at closed sleeve pipe 5 inside.When pushing ahead closed sleeve pipe 5, when jaw was closed, jaw locking safety block 54 ejected downwards down in 53 effects of compression spring, props up the trailing edge of closed sleeve pipe 5, prevent that closed sleeve pipe 5 from returning, thereby the realization jaw was closed and locked.Finish using, upwards boost jaw locking safety block 54, closed sleeve pipe 5 can be return initial position backward, and nail supporting base assembly 2 opens with strap 1.
Drive mechanism can as shown in the figurely comprise support link 41, push broach connecting rod 42 and band cutter tooth bar 43.Wherein, the rear end of the rear end of support link 41 and strap 1 is rotatably connected, and the rear end of the front end of support link 41 and push broach connecting rod 42 is rotatably connected, push broach connecting rod 42 can before and after slide be installed in the closed clamping plate 3.Band cutter tooth bar 43 can before and after slide be installed in the strap 1, and cutting knife 431 and percussion push jack 432 are installed at front end, the middle part is provided with and advances groove 433.
Specifically; The rear end of push broach connecting rod 42 can be connected through bearing pin 44 with the front end of support link 41; And offer chute 31 in closed clamping plate 3 sides; In closed clamping plate 3 set inside restriction push broach connecting rod 42 range of activity, particularly move up and down the positioning bar of scope, bearing pin 44 slides in chute 31.
During use, push ahead closed sleeve pipe 5, nail supporting base assembly 2 is rotated with respect to strap 1; When closed sleeve pipe 5 offsets with limited step 18; The anterior closure of nail supporting base assembly 2 and strap 1, nail supporting base assembly 2 is parallel with nail bin groupware 11 surfaces, and clamps the tissue of precut.
Carry out the cutting and stitching operation afterwards: push closed clamping plate 3; Support link 41 is that rotate at the center with its rear end; Bearing pin 44 is along chute 31 reaches, and the front end of push broach connecting rod 42 moves forward along closed clamping plate 3 thereupon, when touching the propelling groove 433 of band cutter tooth bar 43; To drive cutter tooth bar 43 and move to stiching instrument the place ahead in the lump, realize cutting, sew application with percussion push jack 432 thereby drive cutting knife 431.
In addition, can on band cutter tooth bar 43, a plurality of propelling grooves 433 be set, at least three equidistant propelling grooves 433 of setting for example as shown in the figure.Push closed clamping plate 3, push broach connecting rod 42 drives the cutting and stitching of first section of band cutter tooth bar 43 completion through propelling groove 433 foremost.Unclamp closed clamping plate 3, band cutter tooth bar 43 is motionless, and push broach connecting rod 42 is return and broken away from band cutter tooth bar 43, pushes closed clamping plate 3 once more, and push broach connecting rod 42 contacts with second propelling groove 433 of band cutter tooth bar 43, and promotes the 43 further reaches of band cutter tooth bar.So repeatedly, can progressively advance cutting knife 431 and percussion push jack 432, what be more conducive to cut, sew up controls.
Further, first that makes that jaw locking safety block 54 extands rearward to band cutter tooth bar 43 advances groove 433 places, and its upper edge is equal with the upper edge of band cutter tooth bar 43 or a little more than the upper edge of being with cutter tooth bar 43.In addition, when 5 reaches of closed sleeve pipe, when jaw locking safety block 54 ejected closed sleeve pipe 5, the upper edge of jaw locking safety block should be lower than the bottom land that advances groove 433.
During use; For the first time push closed clamping plate 3, when push broach connecting rod 42 moves to strap 1 place, because jaw locking safety block 54 is in a high position; Equal or a little more than the upper edge of band cutter tooth bar 43; Under the effect of jaw locking safety block 54, the front end of push broach connecting rod 42 can't probe into to advance and promote band cutter tooth bar 43 in the groove 433, but moves forward along the upper edge of jaw locking safety block 54 and push broach connecting rod 42; Contact with the end face of closed sleeve pipe 5 afterwards and promote 5 reaches of closed sleeve pipe, thereby realize the closure of nail supporting base assembly 2 and strap 1.
After closed sleeve pipe 5 reaches put in place, jaw locking safety block 54 ejected closed sleeve pipe 5, unclamps closed clamping plate 3, and push broach connecting rod 42 is return, and closed sleeve pipe 5 can not be return under the effect of jaw locking safety block 54.
Push closed clamping plate 3 once more, because the position of jaw locking safety block 54 moves down, push broach connecting rod 42 will go deep into first and advance the groove 433 interior band cutter tooth bars 43 that also promote to accomplish first section reach.Afterwards, can accomplish whole cutting, sew application through pushing closed clamping plate 3 repeatedly.
The above; It only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction, those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification, equivalent variations or modification, all drop in protection scope of the present invention.
