Abstract

The invention discloses an automatic presser foot lifting and backward and forward sewing device of a sewing machine. The automatic presser foot lifting and backward and forward sewing device comprises a presser foot lifting driver. A first straight rod of the presser foot lifting driver is connected with one end of a pull rope of a pull rope assembly, and the other end of the pull rope is connected with one end of a swing rod. The other end of the swing rod is in contact with one end of a presser foot lifting rear lever which can swing around the lever axis. A presser foot lifting mechanism is connected with the other end of the presser foot lifting rear lever and can be driven to act through swing of the presser foot lifting rear lever. The automatic presser foot lifting and backward and forward sewing device further comprises a backward and forward sewing driver. A second straight rod of the backward and forward sewing driver is connected with one end of a pull rod, and a swing plate seat is connected with the other end of the pull rod. Backward and forward sewing action can be achieved through swing of the swing plate seat. The automatic presser foot lifting and backward and forward sewing device is simple and compact in structure, convenient to install and maintain, low in manufacturing cost and capable of being in comprehensive application with a traditional presser foot lifting and backward and forward sewing mode. The invention further discloses the sewing machine with the automatic presser foot lifting and backward and forward sewing device.
