The application discloses a knotting device and a blood vessel ligator. The knotting device comprises a gun body provided with a knotting groove and a knotting mechanism arranged in the knotting groove. The knotting mechanism comprises a spiral spring and an abutting piece abutting against the spring body of the spiral spring. The spiral spring has a hooking and pulling end and an extending end.
