Abstract

The invention provides a presser foot mechanism and a sewing machine with the same. The presser foot mechanism is used for driving a presser foot rod provided with a presser foot to move so that the presser foot is lifted; and a guide frame is installed on the presser foot rod. The presser foot mechanism comprises a transmission assembly and a jacking part, wherein at least part of the transmission assembly is movably arranged and matched with the guide frame to push the guide frame to move through the transmission assembly, so that the guide frame drives the presser foot rod to ascend to liftthe presser foot; the jacking part is in contact with the transmission assembly, and at least part of the jacking part is telescopically arranged to push the transmission assembly to move; and the jacking part is connected with an electric control assembly, and the electric control assembly adjusts the lifting height of the presser foot rod by adjusting the telescopic amount of at least part of the jacking part to solve the problem that the operating intensity of a presser foot lifting mechanism in the prior art is high.

Description

technical field [0001] The invention relates to the field of sewing, in particular to a presser foot lifting mechanism and a sewing machine with the same. Background technique [0002] At present, most of the sewing machines are controlled by the lower limbs of the human body when lifting the presser foot, and are driven by various transmission components to lift the presser foot. However, since the purely mechanical transmission requires a relatively large force, it requires a relatively large work intensity for the operator. Contents of the invention [0003] The main purpose of the present invention is to provide a presser foot lifting mechanism and a sewing machine with the same, so as to solve the problem of high operating strength of the presser foot lifting mechanism in the prior art. [0004] In order to achieve the above object, according to one aspect of the present invention, a presser foot lifting mechanism is provided, which is used to drive the movement of t...
