The invention discloses an expansion shell anchor head for an anchor rod and rope. The expansion shell anchor head is composed of two expansion shell clamping pieces, a threaded rod, a threaded steel bushing, a connecting plate, a steel bushing and the like. The threaded rod is located between the two expansion shell clamping pieces, and the tail portion of the threaded rod is a reversely-threaded section for assembling the threaded steel bushing; the head portion of the threaded rod is a polish rod section for assembling the steel bushing; a rod tip is arranged at the end of the threaded rod; small shafts are arranged on the two sides of the threaded steel bushing and the steel bushing, and the connecting plate is installed on the small shafts and hinged to small shafts on the two sides of the tail portions and the head portions of the expansion shell clamping pieces. Or, the threaded rod is replaced by a double-end threaded rod; the tail portion of the double-end threaded rod is still a threaded section; the head portion of the double-end threaded rod is a forwardly-threaded section for assembling a forwardly-threaded steel bushing; the rest is the same as the former. The tail end of the threaded rod and the front end of the anchor rod and rope are fixedly connected to serve as an end anchor. During installation of the anchor rod and rope, the threaded rod is driven to rotate to push the threaded steel bushing to move forwards, and the connecting plate enables the two expansion shell clamping pieces to expand and tighten a hole wall. The expansion shell anchor head is suitable for anchoring support of an extremely-soft broken rock mass and is also used for anchoring during drilling of large-diameter holes. The anchoring diameter is increased and can be adjusted, and therefore anchoring force is improved.
