The present invention relates to a rock anchor assembly, which enables easy removal of steel wires and fixing of locker blocks in an insertion hole with uniform pressure. The rock anchor assembly comprises: a fixing block (110) that is inserted into an insertion hole (20); locker blocks (130) that move vertically on the fixing block (110) and come into close contact with the inner wall of the insertion hole (20); a moving block (120) that moves the locker blocks (130) vertically; and pulling blocks (14) that moves the moving block (120).
