Detailed description of the invention
Refer to shown in Fig. 1-5, the present invention relates to a kind of line cutting stitching instrument that adopts 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 provided with nail bin groupware 11, middle part is provided with forward and backward rotational pin 12,13, the rear end of nail supporting base assembly 2 is connected with front rotational pin 12, the front end of closed clamping plate 3 is connected with rear rotational pin 13, and can be separately installed with 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 one section of insertion closed clamping plate 3 bottom surface of leaf spring, the other end is between percussion push rod and closed clamping plate.Closed sleeve pipe 5 can being arranged between forward and backward rotational pin 12,13 along strap 1 to front slide, and the move forward limited step 18 of scope of the closed sleeve pipe 5 of restriction can be set on strap 1.
Preferably, also can be at the outer sheathed shell 51 of closed sleeve pipe 5, shell 51 is fixedly connected with strap 1, between shell 51 inwalls and closed sleeve pipe 5 outer walls, spring 52 is installed, while pushing ahead closed sleeve pipe 5, need to resist the elastic force of this spring 52, as without External Force Acting, closed sleeve pipe 5 is return backward under the elastic force effect of spring 52.
Further, also can on strap 1, by Compress Spring 53, jaw locking safety block 54 be installed.Specifically, can offer in the bottom of strap 1 two grooves 14, the top corresponding with groove 14 is fixed with two spring fixed blocks 15, jaw locking safety block 54 is provided with two upwardly extending connecting portions, jaw locking safety block 54 is arranged on strap 1 below, two connecting portions are in groove 14 stretches into strap 1, and the upper end of Compress Spring 53 is fixedly connected with spring fixed block 15, and lower end is fixedly connected with the connecting portion of jaw locking safety block 54.
In the time that closed sleeve pipe 5 is positioned at initial position, jaw locking safety block 54 is positioned at closed sleeve pipe 5 inside.When pushing ahead closed sleeve pipe 5, when jaw is closed, jaw locking safety block 54 ejects downwards under Compress Spring 53 effects, props up the trailing edge of closed sleeve pipe 5, prevents that closed sleeve pipe 5 from returning, thereby realizes the closed and locked of jaw.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 comprise support link 41, push broach connecting rod 42 and band cutter tooth bar 43 as shown in the figure.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 arranged in closed clamping plate 3.With cutter tooth bar 43 can before and after slide be arranged in strap 1, and at front end, cutting knife 431 and percussion push jack 432 are installed, middle part is provided with and advances groove 433.
Specifically, the rear end of push broach connecting rod 42 can be connected by bearing pin 44 with the front end of support link 41, and offer chute 31 in closed clamping plate 3 sides, the positioning bar that limits push broach connecting rod 42 range of activity, particularly moves up and down scope is set in closed clamping plate 3 inside, and bearing pin 44 is in the interior slip of chute 31.
When use, push ahead closed sleeve pipe 5, can make nail supporting base assembly 2 rotate with respect to strap 1, in the time that closed sleeve pipe 5 and limited step 18 offset, the front portion 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 afterwards cutting and stitching operation: press closed clamping plate 3, support link 41 is rotated centered by its rear end, bearing pin 44 moves forward along chute 31, the front end of push broach connecting rod 42 moves forward along closed clamping plate 3 thereupon, when touch with cutter tooth bar 43 propelling groove 433 time, drive band cutter tooth bar 43 is moved to stiching instrument front in the lump, thereby drive cutting knife 431 and percussion push jack 432 to realize cutting, sew application.
In addition, can on band cutter tooth bar 43, multiple propelling grooves 433 be set, for example, at least three equidistant propelling grooves 433 are set as shown in the figure.Press closed clamping plate 3, push broach connecting rod 42 drives by propelling groove 433 foremost the cutting and stitching that completes first paragraph with cutter tooth bar 43.Unclamp closed clamping plate 3, band cutter tooth bar 43 is motionless, and push broach connecting rod 42 is return and departed from band cutter tooth bar 43, again presses closed clamping plate 3, and push broach connecting rod 42 contacts with second propelling groove 433 with cutter tooth bar 43, and promotes the 43 further reaches of band cutter tooth bar.So repeatedly, can iterative method cutting knife 431 and percussion push jack 432, the operation control of be more conducive to cutting, sewing up.
Further, jaw locking safety block 54 is extanded rearward to first of cutter tooth bar 43 and advance groove 433 places, and upper along equal or a little more than the upper edge with cutter tooth bar 43 with cutter tooth bar 43 of edge it on.In addition,, when closed sleeve pipe 5 moves forward, when jaw locking safety block 54 ejects closed sleeve pipe 5, the upper edge of jaw locking safety block should be lower than the bottom land that advances groove 433.
When use, press for the first time closed clamping plate 3, in the time that 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 with cutter tooth bar 43, under the effect of jaw locking safety block 54, the front end of push broach connecting rod 42 cannot probe into and advance the interior promotion band of groove 433 cutter tooth bar 43, but move forward along the upper edge of jaw locking safety block 54 and push broach connecting rod 42, afterwards with the end contact of closed sleeve pipe 5 and promote closed sleeve pipe 5 and move forward, 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 ejects 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.
Again press closed clamping plate 3, because the position of jaw locking safety block 54 moves down, push broach connecting rod 42 will go deep into first and advance the interior band cutter tooth bar 43 that also promotes of groove 433 to complete first paragraph reach.Afterwards, can, by repeatedly pressing closed clamping plate 3, complete whole cutting, sew application.
The above; it is only preferred embodiment of the present invention; not the present invention is done to 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.
