The last rear flank of the vertical through hole of top external part cover of above-mentioned pressure shaft is equipped with the depression bar folder of restriction pressure shaft position.
The upper end of above-mentioned pressure shaft and the internal thread of voltage regulation screw are spirally connected, and the external thread rotary of voltage regulation screw is located on the upper wall of head, are set with compression spring on the pressure shaft between depression bar folder and the voltage regulation screw, and the lower end of pressure shaft is set with the depression bar axle sleeve.
Be provided with axle sleeve between the both sides of above-mentioned swing axle bed and the adjusting connecting rod.
Be provided with the wool malthoid of oil lubricating movement part on above-mentioned swing axle bed and the swinging axle.
Above-mentioned drive link is stretched out casing at the backside openings place of casing, and the clearance gap place is by the rubber stopper shutoff.
The utility model is compared the outstanding advantage of prior art:
1, the utility model makes when making and to realize steadily feeding synchronously, reduces or avoids causing the variation in a big way of needle gage length because of stitching fast speed, and it is still smooth, well-balanced to make the back lining, is difficult for giving a discount, wrinkling, has guaranteed the even, attractive in appearance of sewings stitching;
2, the utility model makes when making thicker sewing and crossing the position of bone (piece junction), and feeding driving force is preferably arranged, and realizes friction feeding, and what guaranteed to make is smooth and easy;
3, the oil circuit of the utility model design is partly lubricated, adopts wool felt store oil lubricated, thereby guarantees that each main motion parts can lubricate timely and effectively, avoids the easy to wear and possible stuck phenomenon of parts;
4, the drive link casing after-opening of the utility model design is carried on the back out driving, and with rubber stopper shutoff space, makes dust, line bits be difficult for getting in the machine body, avoids the long-pending stifled machine that influences of dirt to run well.
