The specific embodiment
See also shown in Fig. 1-8, a kind of straight cuts stiching instrument that adopts novel cutting knife resetting-mechanism of the present invention mainly comprises strap 1, nail supporting base assembly 2, closed clamping plate 3, band cutter tooth bar 43 and cutting knife resetting-mechanism.
Band cutter tooth bar 43 can before and after slide be installed in the strap 1, and be connected with steel band 435 in the rear end of band cutter tooth bar 43.
The cutting knife resetting-mechanism comprises reseting gear 61, receives moving gear 62 and band cutter tooth wheel 63.
Wherein, receive the moving gear 62 rotating rear ends that are installed in strap 1, what comprise fixed connection receives active toothed disk 621 and stopping fluted disc 622.
The reseting gear 61 rotating rear ends that are installed in closed clamping plate 3, when closed clamping plate 3 and strap 1 closure, reseting gear 61 meshes with the active toothed disk 621 that receives that receives moving gear 62.
The band cutter tooth is taken turns 63 coaxial packages and is being received the receiving between active toothed disk 621 and the stopping fluted disc 622 of moving gear 62; One side of band cutter tooth wheel 63 is provided with when closed clamping plate 3 and strap 1 closure; Can cooperate the locking tooth 631 that stops band cutter tooth wheel 63 clockwise (are benchmark with Fig. 1 visual angle) to be rotated with stopping plectrum 34, and be provided with prevention band cutter tooth wheel 63 with respect to the stopping mechanism that clockwise rotated by moving gear 62 with stopping fluted disc 622 corresponding sides.Band cutter tooth bar 43 is connected with band cutter tooth wheel 63 through 435, and steel band 435 twines with band cutter tooth wheel 63, and the tail end of steel band 435 is fixed on the band cutter tooth wheel 63.
The stopping mechanism of band cutter tooth wheel 63 can be made up of retreat stop block as shown in the figure 632 and leaf spring 633; Retreat stop block 632 is rotatably connected with band cutter tooth wheel 63; Leaf spring 633 1 ends are fixedly connected with band cutter tooth wheel 63, the other end and receive the tooth on the active toothed disk 622 to clamp retreat stop block 632 from both sides.Stopping mechanism cooperates with the stopping fluted disc 622 that receives moving gear 62, makes band cutter tooth wheel 63 only with respect to rotated counterclockwise by moving gear 62, and can not take place to clockwise rotate relatively.
When carrying out the cutting and stitching operation, along with the reach of band cutter tooth bar 43, band cutter tooth wheel 63 clockwise rotates; At this moment; Retreat stop block 632 promotes to receive active toothed disk 622, receives moving gear 62 cutter tooth wheels 63 going along with to clockwise rotate (as according to Fig. 6 visual angle, then being to promote counterclockwise to rotate) in the lump.
After accomplishing cutting, sew application; Remain closed the closure state of clamping plate 3 and strap 1, through clockwise rotating reseting gear 61, reseting gear 61 drives and rotated counterclockwise by moving gear 62; Receive active toothed disk 622 to promote retreat stop block 632; Rotate synchronously thereby drive band cutter tooth wheel 63, band cutter tooth wheel 63 is rolled steel band 435, and band cutter tooth bar 43 is drawn back into the percussion front position.
After cutting knife resets fully; Reseting gear 61 is gone back to original position counterclockwise, clockwise rotated by moving gear 62, at this moment thereupon; The locking tooth 631 that stopping plectrum 34 props up band cutter tooth wheel stops band cutter tooth wheel 63 to clockwise rotate; Thereby keep motionless, and leaf spring 633 compressive deformations, retreat stop block 632 slips over from receiving active toothed disk 622.
Preferable, also can be provided with handle as shown in the figure 611 on the reseting gear 61, so that cutting knife clockwise rotates reseting gear 61 when resetting.And back-moving spring 64 is installed between reseting gear 61 and closed clamping plate 3, and cutting knife resets when accomplishing, and reseting gear 61 goes back to original position automatically counterclockwise under spring 64 effects.
The present invention can install and fix bearing pin 612 in the rear end of closed clamping plate 3; Reseting gear 61 can be realized rotatable the installation through this fixed pin shaft; The upper end of stopping plectrum 34 then can be fixedly connected with this fixed pin shaft; During closed closed clamping plate 3, the lower end of stopping plectrum 34 promptly acts on the locking tooth 631 of band cutter tooth wheel 63.
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.
