Problems solved by technology
[0005] In order to make up for the deficiencies of the existing technology, it is necessary to use scissors to cut it after the sewing is completed. In actual operation, the scissors are generally placed far away from the machine needle so that the overall area of the workbench can meet the paving of the fabric. , and then after sewing, it is more laborious to stretch your arms to go to a distance to take the scissors, and it will delay the processing time of the fabric. At the same time, the scissors are easy to lose, which further affects the progress of the fabric processing. Structure and Sewing Machine

The invention belongs to the technical field of sewing machine production, and particularly relates to a sewing machine trimming presser foot lifting structure and a sewing machine. The sewing machine trimming presser foot lifting structure comprises an arc-shaped blade and a vertical straight gear plate, wherein the arc-shaped blade is movably hinged to the interior of a placement groove through a torsional spring; the placement groove is located at the front end of a working platform; and strip-shaped through grooves are formed in the positions, corresponding to the arc-shaped blade, of the top and the bottom of the working platform. By arranging the arc-shaped blade and a pedal plate, the arc-shaped blade can be turned over by treading the pedal plate downwards, the arc-shaped blade can stretch out of the strip-shaped through groove in the top of the working platform while being turned over, and then a sewing thread which is fixedly connected with fabric and pulled to the strip-shaped through groove can be cut off, so that extra scissors do not need to be used for cutting off the thread connected with the fabric, the situation that the scissors are prone to being lost when the scissors are used for cutting off the thread is avoided, the arc-shaped blade is located at the position close to a machine needle, then the thread can be rapidly cut off after sewing is completed, and the working efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of sewing machine production, and specifically relates to a sewing machine thread trimming and presser foot lifting structure and a sewing machine. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material. The sewing machine can sew fabrics such as cotton, linen, silk, wool, and man-made fibers, and products such as leather, plastic, and paper. The stitches are neat and beautiful, flat and firm, with fast sewing speed and easy use. Art forms such as computer embroidery. [0003] At present, with the progress of industrialization, various sewing machines are also being updated day by day, but at present, household sewing machines and sewing machines in some manual workshops still use old-fashioned electric sewing machines. Old-fashioned electric sewing machine...
