Abstract

The invention provides a sewing machine which comprises a case, an outer presser foot, an inner presser foot, a connecting structure and a driving motor. The outer presser foot is movably arranged inthe vertical direction. The inner presser foot is movably arranged in the vertical direction. The connecting structure is connected with the inner presser foot and the outer presser foot. An output shaft of the driving motor is connected with the connecting structure, and the driving motor is used for driving the connecting structure to move, so that the inner presser foot and the outer presser foot are driven by the connecting structure to move in the opposite directions. The forward rotating angle and reverse rotating angle of the output shaft of the driving motor is controlled to adjust thealternation amount between the inner presser foot and the outer presser foot. According to the sewing machine, the problem that a sewing machine in the prior art cannot adjust the alternation amountof an inner presser foot and an outer presser foot is solved.

Description

technical field [0001] The invention relates to the technical field of sewing machine manufacturing, in particular to a sewing machine. Background technique [0002] In the sewing machine that does not use the feed teeth to move the cloth, in order to prevent the friction between the cloth and the needle, causing the cloth and the needle to rise together and produce skipped stitches, an inner presser foot is usually installed in the outer presser foot. When the sewing machine is working normally, the inner presser foot and the outer presser foot alternately press the object to be sewn on the needle plate. [0003] The alternating amount between the inner presser foot and the outer presser foot of the sewing machine in the prior art cannot be adjusted. amount, sewing will not work properly. Contents of the invention [0004] The main purpose of the present invention is to provide a sewing machine to solve the problem that the sewing machine in the prior art cannot adjust ...
