Large-deformation energy-absorbing anchor rod with simplified structure

A large-deformation energy-absorbing anchor rod with a simplified structure comprises a nut, a washer, a supporting plate, a rod body and an anchor head; the nut, the washer and the supporting plate are mounted at one end of the rod body sequentially in a sleeving mode, the anchor head is fixedly mounted at the other end of the rod body, the rod body is divided into an anchoring section and a non-anchoring section, the rod body at the anchoring section directly makes contact with an anchoring agent for anchoring cementation, and the rod body at the non-anchoring section is sleeved with an anchoring agent isolating sleeve in a wrapped mode; the outer surface of the anchoring agent isolating sleeve directly makes contact with the anchoring agent for anchoring cementation, and the contact face between the inner surface of the anchoring agent isolating sleeve and the rod body is subjected to lubrication antifriction treatment; the non-anchoring section of the rod body penetrates through astructural face or a pote
