Both ends of the spring plate are fixedly connected to the anti-detachment rod and the support rod, respectively. The stop block is fixed to the end of the support rod. The spring plate and the stop block are located on both sides of the anti-detachment rod.

[0019] To achieve the above technical solution, the bobbin is moved from top to bottom towards the support rod. The lower end of the bobbin contacts the anti-detachment rod, which bends downward and is located inside the bobbin. As the bobbin continues to move, after the bobbin separates from the anti-detachment rod, the anti-detachment rod resets due to the elastic force of the spring. When the bobbin moves upward, it contacts the anti-detachment rod and pushes it upward. The anti-detachment rod then contacts the stop block and is limited, preventing the bobbin from coming out of the support rod, thus improving stability during the sewing process.
