The utility model relates to a fish tail type anchor rod. The fish tail type anchor rod comprises an anchor rod, wherein the front end of the anchor rod is provided with an opening, and a fish tail wedge is arranged in the opening. According to the fish tail type anchor rod provided by the utility model, because the front end of the anchor rod is provided with the fish tail wedge, after the anchor rod is driven into a hole, the tail part of the anchor rod can be sufficiently expanded by the fish tail wedge, and after cement mortar in the hole is solidified, the anchoring strength of the anchor rod can be enhanced so as to reduce the construction depth of the anchor rod or reduce the arrangement depth of the anchor rod, and therefore, the work amount and the engineering cost of the anchor rod are saved. The fish tail type anchor rod has the advantages of simple manufacturing, convenience, easy application and practicability and is particularly suitable for rocky side slopes with poor geology.
