Problems solved by technology

[0005] In order to make up for the deficiencies in the prior art, it is difficult to make the fabric move along the desired direction when the novice sewing fabric is pulled by hand, so that the sewing line is not in a straight line and deviates, and when it is necessary to move the fabric on a piece of fabric When sewing multiple straight sewing lines with equal intervals, it is obviously a problem that simply moving by hand cannot make the spacing between the sewing lines equal. A double-chain stitch sewing machine proposed by the present invention

Abstract

The invention belongs to the technical field of double-chain stitch sewing machines, and particularly relates to a double-chain stitch sewing machine which comprises a working platform, a machine base and machine needles, wherein the machine base is fixedly mounted on the upper surface of the working platform; the two groups of machine needles are arranged at the end part of the machine base; horizontal sliding rails are arranged on the front side and the rear side of the upper surface of the working platform; a first sliding block is arranged in the horizontal sliding rail located at the front end in a sliding mode; and a second sliding block is arranged in the horizontal sliding rail located at the rear end in a sliding mode. An elastic pressing plate can press two sides of fabric needing to be sewn to the top of a guide sliding plate, then the position of the fabric is fixed, and then the guide sliding plate is pushed to slide in a limiting sliding groove body, so that threading of the machine needles can be more straight, the stitch neatness of sewn clothes is improved, and thus the quality of the clothes is improved. The device is particularly suitable for being used by a sewing novice, and the situation that a hand is punctured by the needles when the novice puts the fabric needing to be sewn to be close to the machine needles and tightly presses the fabric on the working platform with the hand is avoided.

Description

technical field [0001] The invention belongs to the technical field of double-chain stitch sewing machines, in particular to a double-chain stitch sewing machine.
