The invention provides a tail-breaking tail-taking device for a blind hole installation steel wire thread sleeve. The tail-breaking tail-taking device comprises a tail-breaking rod and a positioning rod, and the tail-breaking rod and the positioning rod are tightly attached to form a cylindrical rod structure; a convex block is arranged on the front end surface of the tail breaking rod, a tail-breaking block is protruded on the left side surface of the convex block, and a tail breaking groove for inserting a straight handle part is formed in the front end surface of the tail breaking block andthe front end surface of the tail breaking rod, a positioning groove corresponding to the tail breaking groove is formed in the front end surface of the positioning rod, the straight handle part extends into the positioning groove after penetrating through the tail breaking groove, and the groove bottom of the positioning groove is flush with the front end surface of the tail breaking rod. The tail-breaking tail-taking device is provided with a limiting, inserting, positioning and hooking structure corresponding to a tail handle, so that the tail handle can be accurately clamped into the tailbreaking groove and the positioning groove, and then the tail handle is pulled off through external force, after the tail handle is broken, the tail handle is hooked and limited inside the tail breaking groove by the tail breaking block, the tail handle is ensured to be smoothly taken out, the tail-breaking tail-taking device is suitable for the tail-breaking operation requirements after the steel wire thread sleeve in the blind hole is installed, and have strong practicability.
