The invention discloses a high-strength anti-pull anchoring part with a bending groove. The anchoring part is characterized in that a thick-wall expansion pipe is designed, the bending groove is formed in the outer surface of the upper part of the thick-wall expansion pipe in the direction of the cross section, the shape of the cross section of the thick-wall expansion pipe can be a petal-shaped shape. According to the anchoring part, the technical features are clear, the method is ingenious, the process is simple, manufacturing is easy, the cost is low, the use is convenient, safe and firm anchoring or reinforcing or fixing or supporting can be realized on various anchoring base bodies, the universality is very good, the application range is very wide, and the anchoring part is a revolution of a traditional anchoring part in the true sense.
