Sewing machine with hand pressing prevention device

Abstract

The invention relates to the technical field of sewing machines, and discloses a sewing machine with a hand pressing prevention device. The sewing machine is characterized in that a buffer assembly ismounted at one end of a sewing machine body, the upper surface of a presser foot is in threaded connection with a fastening bolt, the rear surface of the presser foot is in sliding connection with anextendable plate, a limiting block fixedly connected to one end of the extendable plate is further slidably connected into the presser foot, and compacting assemblies are mounted on the two sides ofthe upper surface of the extendable plate correspondingly. According to the sewing machine, the periphery of the sewing machine body can be shielded through a shielding frame, the sewing machine bodyis prevented from being damaged by external force, meanwhile, the sewing machine body can be subjected to dustproof treatment through the shielding frame, and follow-up use is easy; and a certain buffering effect can be achieved in the pressing-down process of the presser foot through the buffer assembly, when fingers of a user make contact with the bottom of the presser foot, the hands of the user can be protected through elastic deformation of a second spring, a third spring and an air bag, and the fingers of the user are prevented from being crushed by the presser foot.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to a sewing machine with an anti-pressure hand device. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing materials. The sewing machine can sew cotton, hemp, silk, wool , artificial fiber and other fabrics and leather, plastic, paper and other products, the stitches are neat and beautiful, flat and firm, with fast sewing speed and easy use. And it derived art forms such as hand-push embroidery and computer embroidery. [0003] However, during use of existing sewing machines, since the presser feet are all directly pressed down, there is no corresponding buffer mechanism, which easily causes the presser feet to cause crushing injuries to the fingers of the user. , lack of corresponding protective measures, after being impacted b...

Problems solved by technology

[0003] However, during the use of existing sewing machines, since the presser feet are all directly pressed down, there is no corresponding buffer mechanism, which easily causes the presser feet to cause crushing injuries to the fingers of the user. , lack of corresponding protective measures, after being impacted by external force, it is prone to damage. Finally, the area of ​​the presser foot is limited, and it is difficult to increase the pressing area of ​​the fabric
