The invention discloses a ham segmented binding structure. The structure comprises a fixed disk and a first driving motor for driving the fixed disk to rotate. Multiple pressing binding mechanisms are arranged on the fixed disk at equal intervals around the center of the fixed disk. The rotary pressing binding mechanisms having high efficiency and simple structures can fast finish pressing binding closing. A gap formation mechanism can form an empty casing section between ham sections before pressing binding. In pressing binding, meat is not wasted. A U-shaped pressing nail has a small size so that a cost is saved and firm binding effects are obtained.
