The invention relates to an adjustment disk fixing apparatus of a sewing machine, a adjustment disk apparatus and a sewing machine having the adjustment disk apparatus, the adjustment disk fixing apparatus, composed of a shaft member, a adjustment disk member and a backing pin equipped with the cotterway of the sewing machine, comprises a fixing bushing for surrounding upper edge column jacket surface of the shaft member for stitch seam adjustment with a fixing slice; a fixing loop plugged into the column jacket surface of the fixing slice, and with a side of fixing hole having screw concave; and a fixing member combined to the fixing hole through thread mode and applying pressure to the fixing slice. the invention effectively prevent error action of the adjustment disk virtually rotating in stitch seam progressive increase direction by impact and vibration etc. in condition that stitch seam adjustment is finished, accordingly poor sewing workmanship of sewing is reduced, preparation performance is improved, stitch seam can be adjusted and adjustment disk fixed easily.
Description
technical field [0001] The present invention designs an adjusting dial device that can adjust and select the needle interval in a sewing machine, especially one that can prevent the set needle interval from being The adjustment disc fixing device of the sewing machine, the adjustment disc device and the sewing machine equipped with the adjustment disc device can be removed, thereby reducing sewing defects, improving productivity, and simplifying the structure. Background technique [0002] A sewing machine is a device that mechanizes the sewing (STITCH) operation of fabric pieces. The repetition interval (PITCH) of the above-mentioned sewing operation of the above-mentioned sewing machine is called one stitch. [0003] The sewn goods sewn by the above-mentioned sewing machine can be adjusted according to factors such as its purpose of use and the type of fabric, or the number of stitches (hereinafter referred to as "stitches"). The above stitches are the number of stitches...
