Abstract

The invention provides a sewing machine. The sewing machine comprises a machine shell, an outer presser foot, an inner presser foot, a connecting assembly, a driving structure, a limiting connecting rod and a manual adjusting mechanism, wherein the outer presser foot and the inner presser foot are movably arranged in the vertical direction, the connecting assembly is connected with the outer presser foot and the inner presser foot, the connecting assembly comprises a swinging part, and the driving structure is in driving connection with the swinging part; the driving structure drives the swinging part to swing, so that the inner presser foot and the outer presser foot are driven by the connecting assembly to move towards opposite directions, the limiting connecting rod is pivotally arranged in the machine shell with the first end of the limiting connecting rod as the rotation center, the limiting connecting rod is connected with the driving structure, and the manual adjusting mechanismis in driving connection with the first end of the limiting connecting rod so as to adjust the position of the rotating center of the limiting connecting rod through the manual adjusting mechanism toadjust the size of a preset angle, so that the alternating amount between the inner presser foot and the outer presser foot is adjusted. The sewing machine solves the problem that in the prior art, asewing machine cannot adjust the alternating amount between an inner presser foot and an outer presser foot.

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 ...
