Anchor rod is the main load-bearing component, and the commonly used materials include steel, glass fiber reinforced polymer, etc. Anchor head is used to anchor the anchor rod in the soil or rock mass, and the anchor rod is connected with the anchor head through steel wire or cable.

[0003] The existing anchor rod assembly, when supporting roadway surrounding rock, cannot resist the shear stress of the near zone of the roadway surrounding rock, causing the anchor rod assembly to shear and break, resulting in a decrease in the local stability of the surrounding rock, large-scale deformation or damage of the surrounding rock, and a decrease in the safety and stability of underground construction.

[0004] For example, according to the anchor rod provided in the announcement No. CN210164493U, the main anchor rod and the connecting anchor rod are connected together through a connecting nut.
