The invention relates to the technical field of medical apparatuses and instruments, and discloses a nickel-titanium memory alloy ship-shaped connector which comprises a connecting frame, two annular frames, a connecting rod and a connecting rod. An extension part is arranged on the ring frame, the extension part comprises two extension arms, and the two extension arms are both connected to the inner wall of the ring frame in a sliding mode; a reset part is further arranged on the ring frame and used for manually driving the two extension arms to retract into the ring frame. Through the arrangement of the extension parts, the two extension arms can automatically extend out and form an annular structure with the annular frame after the annular frame is in contact with a bone, so that the stability of fixing the bone is greatly improved, independent installation operation is not needed, the operation time is saved, and by utilizing the characteristics of nickel-titanium memory alloy, the operation efficiency is greatly improved. The annular frame and the extension arms above the annular frame can automatically hold the skeleton tightly after being heated, use of skeleton fixing pieces is reduced, and then damage to the skeleton is reduced.
