The invention provides a reinforced high-holding-power anchor. The reinforced high-holding-power anchor comprises an anchor rod (1) and an anchor head, wherein an anchor shackle (3) is arranged at the top end of the anchor rod (1); a pin hole (2) is formed in the bottom end of the anchor rod (1) and penetrates the anchor rod (1); reinforcing structures are respectively arranged on two opposite sides of the anchor rod (1) along the central line of the pin hole (2); each reinforcing structure is an annular body (4), the two annular bodies (4) are symmetrically arranged on two sides of the pin hole (2), and the two annular bodies (4) are concentric with the pin hole (2). The reinforced high-holding-power anchor has the advantages that the reinforcing structures are arranged on the periphery of the pin hole, and the mechanical strength at the connection of the anchor rod and the anchor head is increased.
