美国采购需求：s5188，穿线机

I'm reaching out regarding a badminton stringing machine I found on your website, which closely resembles a specific model I currently own. However, I want to clarify that my machine is electronic, not manual. Over time, the clamps that hold the racket have become worn out, and I'm in need of replacements to ensure optimal performance during stringing. Could you please provide information on how I can order new clamps for my machine? If you have compatible options available, I would appreciate details on the pricing and delivery times. Looking forward to your prompt response so I can get back to stringing soon!
