Rotating hooking mechanism: a mechanism that uses a rotating hooking member to complete the hooking action, which is divided into:
Rotary hook hooking mechanism: the rotating hook body in the lockstitch sewing machine is driven by a rotating mechanism, hooks the needle thread loop, and passes through the shuttle sleeve to interweave with the shuttle thread to form a lockstitch.
Rotary hook hooking mechanism: in the single-thread chainstitch sewing machine, the diamond-shaped shuttle hook that does not wear the sewing thread is driven by a rotating mechanism to hook the needle thread loop under the sewing material to form a single-thread chainstitch.
Swinging hooking mechanism: a mechanism that uses a swinging hooking member to complete the hooking action.
Swinging hook hooking mechanism: the swinging shuttle body in the lockstitch sewing machine is driven by a semi-rotating mechanism, and the swinging shuttle is used to hook the needle thread loop and pass through the swinging shuttle and its shuttle sleeve to interweave with the shuttle thread to form a lockstitch.
Curved needle thread hooking mechanism: In the chain stitch sewing machine, a hooking piece with a curved thread is inserted, which swings back and forth, hooks the thread loop on the needle or the thread on another hooking piece to sew together, forming a mechanism of chain stitch.
Thread hooking mechanism: In the single-thread chain stitch sewing machine, a hook-shaped thread hooking piece without thread is driven by the swing mechanism to hook and expand the thread loop of the needle thread under the sewing material, forming a mechanism of single-thread chain stitch.
Fork needle thread hooking mechanism: A thread hooking piece with a fork at the end that does not insert the thread is driven by the swing mechanism to fork the thread and interconnect it to form a mechanism of chain stitch.
