Anti-rockburst anchor rod

The invention provides an anti-rockburst anchor rod, which relates to the technical field of anchor rods and comprises a sliding rod, an elastic rod, a combined member, a strain sensor, a strain indicator and an end rod. When rock burst or rock stratum movement occurs, under the impact or extrusion of rock, the sliding rod moves towards the interior of the elastic rod and compresses the elastic piece, so that the elastic rod slides towards the end rod in the combined component, and after the elastic rod drives the strain sensor to make contact with the end rod, the strain sensor is pressed and deformed; the strain sensor feeds back a signal generated by compressive deformation to the strain indicator, so that a worker can know the compressive condition of the sliding rod; in addition, the anchor rod can absorb kinetic energy of rocks to a certain extent when rockburst occurs, the speed of the rocks is reduced, the damage of the rocks to surrounding objects is reduced, the anchor rod is not prone to falling of
