The application discloses a handle structure with a spiral curved surface lock, which is used for locking a plug and a socket of a fluid connector, a handle accessory of the handle structure is connected to the plug through a shaft pin, the handle accessory comprises a locking part, a spiral curved surface for guiding a locking column on the socket is arranged on the locking part, and a locking groove for fixing the locking column is arranged on the locking part, the locking groove is connected with the spiral curved surface, a convex part is arranged at a position where the spiral curved surface transitions to the locking groove, and the locking column is connected to the locking part from the bottom to the top of the handle structure; the force applying mode from the bottom to the top of the application overcomes the self-locking in the connecting process of the existing structure, thereby overcoming the defect that the connection is stuck; the structure that the inflection point is added in the locking groove ensures the locking, prevents the self-unlocking phenomenon from occurring in the use process, and overcomes the defect that the locking shakes through the limiting structure.
