Expansion skid resistance anchor rod

The utility model discloses an expansion skid resistance anchor rod. The expansion skid resistance anchor rod is composed of an expansion casing, a grouting pipe, a leaf spring, a tray, nuts, a stop grouting plug, a casing spacer and a casing tray. A through long grouting pipe is arranged at the center of a rod body and grouting holes are formed in the grouting pipe. The external shape of the expansion casing is in a cylinder, two through long casing seams are arranged on the casing so that the casing can be divided into two parts. Grouting holes are formed in the grouting pipe, and a hook hole is formed in the grouting pipe between the grouting holes; an elastic hook on the leaf spring stretches into the hook hole, so that the leaf spring and a steel pipe body are connected firmly; compression deformation seams and the grouting holes are formed in the leaf spring, and slurry can enter anchor eyes through the compression deformation seams and the grouting holes on the leaf spring, so that the leaf spring can be placed between the slurry to fully fix the anchor rod. According to the device, skid resistance anchoring requirements can be achieved and the problem that the anchor rod slips in unfavorable geology can be solved.
