Resistance-increasing energy-absorbing anchor rod

A resistance-increasing and energy-absorbing anchor rod comprises a first-stage anchoring element, a second-stage anchoring element, a third-stage anchoring element, a resistance-increasing and energy-absorbing element, a rod body, a nut and a tray. The first-stage anchoring element, the second-stage anchoring element, the resistance-increasing energy-absorbing element and the third-stage anchoring element are sequentially installed at the drill hole inserting end of the rod body. The second-stage anchoring element is fixedly matched with the rod body through a nut; the third-stage anchoring element is in limiting fit with the rod body through a nut. The second-stage anchoring element and the third-stage anchoring element are matched with the resistance-increasing energy-absorbing element, so that the supporting requirements of various severe working conditions can be met; the resistance-increasing energy-absorbing element can greatly improve the deformation capacity of the anchor rod while ensuring high anch
