The specific embodiment
How further specify the utility model below in conjunction with accompanying drawing 1-Fig. 3 realizes:
As shown in Figure 1 and Figure 2, needle gage is regulated fork 2 and is axially fixed in (casing is not drawn among the figure) on the casing by needle gage adjusting swing link pin 3 and needle gage adjusting fork packing ring 1.Backstitching axle 16 is installed on the casing by backstitching an axle sleeve (preceding) 17 and backstitching an axle sleeve (back) 32, collar 30 and collar screw 31.As shown in Figure 3, backstitch crank (on) 29 by backstitch crank holding screw 14 be fixed on backstitch the axle 16 on.Backstitch platform 22 and be installed in (base plate is not drawn among the figure) on the base plate, backstitch crank (descending) 23 and link together by backstitching crank (descending) screw 24 and backstitching platform 22.
Big needle distance bidding quotation panel 11 is attached on the needle gage bidding quotation 10, needle gage bidding quotation location-plate 9 is arranged thereafter, big needle distance bidding quotation panel 11 links together by needle gage bidding quotation screw lining 12 and bidding quotation screw 13 with the needle gage bidding quotation, on the needle gage bidding quotation location-plate 9 stop dog chart 5 is housed, latch 6 and needle gage button spring 8, when counterclockwise or the needle gage bidding quotation 10 that turns clockwise, numerical value shown in the big needle distance bidding quotation panel 11 increases or when reducing, big needle distance adjusting screw(rod) 7 screws out or precession (sealing ring 4 is housed on the big needle distance adjusting screw(rod) 7), needle gage is regulated the pulling force of fork 2 by fork spring 36, making needle gage regulate fork 2 rotates, contact with big needle distance adjusting screw(rod) 7, needle gage regulate fork 2 rotate by with backstitch spacer pin 15 and contact, make backstitch crank (on) 29 rotate, make again and backstitch crank connecting link 28 and move up or down, (backstitch crank connecting link 28 by the crank connecting link pin (on) 18, E type ring washer 27 and backstitch crank (on) 29 connect, backstitch crank connecting link 28 by backstitching crank (descending) 23, backstitch crank (descending) screw 24, crank connecting link pin (descending) 25, packing ring 26 and E type ring washer 27 connect), drive again and backstitch crank (descending) 23 rotations, thereby make to backstitch platform 22 and and then rotate (slide block guide rail 21 by guide rail hold-down screw 19 and spring washer 20 with backstitch platform 22 and be connected), make the needle gage increase or reduce.
When above-mentioned big needle distance adjusting screw(rod) 7 when needle gage is regulated fork 2 and contact, the little needle gage adjusting screw(rod) 33 of little needle gage bidding quotation panel 34 controls and needle gage adjusting fork 2 are discontiguous.When we little needle gage bidding quotation 34 on shown in needle gage during less than the numerical value shown in the big needle distance bidding quotation 11, (backstitching close pin cylinder 35 is controlled by the close joint key switch under the effect that backstitches close pin cylinder 35, do not draw among the figure), needle gage is regulated fork 2 and is contacted with little needle gage adjusting screw(rod) 33.(needle gage adjusting this moment fork 2 does not contact with big needle distance adjusting screw(rod) 7) is because needle gage is regulated the rotation of fork (2), make backstitch crank (on) 29 also and then rotate by backstitching spacer pin 15, make again and backstitch crank connecting link 28 and move downward, drive again and backstitch crank (descending) 23 rotations, backstitch and then rotation of platform 22 thereby make, needle gage is reduced, reach the purpose of close joint.
When the big needle distance adjusting screw(rod) 7 in the big needle distance adjusting device when needle gage is regulated fork 2 and contact, little needle gage adjusting screw(rod) 33 in the little needle gage adjusting device and needle gage adjusting fork 2 are discontiguous.When the user wants to use little needle gage close joint,, can drive and backstitch close pin cylinder and withstand needle gage and regulate fork, contact, thereby realize that little needle gage sews with little needle gage adjusting device as long as click the close joint key switch.As restoring to the original state, as long as click the close joint key switch again, then backstitch close pin cylinder and promptly quit work, needle gage is regulated fork 2 and is restored to the original state under 36 effects of fork spring, contacts with the big needle distance adjusting device, sews thereby recover former needle gage.The user can raise the efficiency greatly like this.
