Description

Technical Field

[0001] The utility model relates to the technical field of sewing equipment and embroidery equipment, in particular to a shuttle frame capable of replacing a plane regulating piece under a needle groove of the shuttle frame. Background Art

[0002] The sewing machine is provided with a rotary hook on the lower side of the needle plate. The rotary hook includes a shuttle bed and a shuttle frame. The shuttle bed rotates integrally with the shaft as the needle moves up and down, and can rotatably support the shuttle frame. The shuttle frame can rotate independently of the shuttle bed, and includes a locking mouth on its outer peripheral portion. The locking mouth engages with the shuttle stopper included in the sewing machine to stop the rotation amplitude of the shuttle frame, so that the shuttle frame does not rotate with the shuttle bed. The upper thread passes through the needle eye of the machine needle. The sewing machine uses the shuttle bed to capture the upper thread of the machine needle after passing through the fabric, and interweaves the upper thread with the bottom thread held by the shuttle frame in the stopped state to perform sewing.
