Visual detection anchor rod with fixed torque mechanism

The utility model provides a visual detection anchor rod with a fixed torque mechanism. The anchor rod comprises an anchor rod body, an anchor rod threaded section is arranged on the upper portion of the anchor rod body, a fixed-torque cap of the anchor rod is arranged on the top of the anchor rod threaded section, a fixed-torque fracture ring groove is formed between the fixed-torque cap and the anchor rod threaded section, and the minimum diameter of the fixed-torque fracture ring groove is smaller than the diameter of the fixed-torque cap and the diameter of the anchor rod threaded section. The section shape of the fixed torque cap meets the condition that when the inner sleeve of the torsional shear wrench is sleeved with the fixed torque cap, the inner sleeve and the fixed torque cap cannot rotate relatively in the circumferential direction. The anchor rod end fixed torque structure is simple in structure and reasonable in design, and when the anchor rod end fixed torque structure is used, the anchor rod
