Abstract

The invention provides a sewing machine comprising a housing, an outer presser foot, an inner presser foot, a connecting assembly, a driving structure and a limiting connecting rod. The outer presserfoot is movably arranged in the vertical direction; the inner presser foot is movably arranged in the vertical direction; the connecting assembly is connected with both the outer presser foot and theinner presser foot and comprises a swinging piece; the driving structure is in driving connection with the swinging piece; the driving structure is used for driving the swinging piece to swing, so that the inner presser foot and the outer presser foot move towards opposite directions under the driving of the connecting assembly; and the limiting connecting rod is pivotally arranged in the housing,and the limiting connecting rod is connected with the driving structure and used for limiting the swinging piece to swing within a preset angle, wherein the rotation center of the limiting connectingrod can be adjusted, so that a preset angle can be adjusted by adjusting the position of the rotation center of the limiting connecting rod, and the alternating quantity between the inner presser foot and the outer presser foot can be adjusted. The sewing machine solves the problem that the sewing machine in the prior art cannot adjust the alternating quantity of the inner presser foot and the 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 ...
