When the anchoring device adopting the composite supporting technology in the technical scheme is used, the anchor rope body penetrates through the through hole, the drill rod is connected with the external drilling machine, the positioning ring moves in the hole, the ball contacts with the inner wall of the hole, and the ball can move through the sliding block and the spring.

Preferably, a drill rod is arranged in the connecting sleeve, and the drill rod is of a hollow design. The drill rod can be connected with an external drilling machine.

Preferably, through holes distributed in a circular array are formed in the positioning ring, and anchor cable bodies are arranged in the through holes. The anchor rope body can wear inside the through-hole, and the anchor rope body can follow the drilling rod and take place to remove.

Preferably, the outer wall of one end of the sliding block is rotatably provided with a ball, and the ball is positioned outside the positioning ring. The balls ensure the smoothness of the movement of the positioning ring in the hole.

Preferably, a spring is arranged on one side of the inner wall of the chute, and the sliding block is elastically connected with the inner wall of the chute through the spring. The spring force ensures the position stability of the slide block.

Compared with the prior art, the utility model has the beneficial effects that: according to the utility model, through arranging the sliding groove, the ball and the spring, the effect of moving fluency of the positioning ring is achieved, the positioning ring is prevented from being clamped in the hole, the moving fluency of the positioning ring in the hole is ensured, and the anchoring efficiency is ensured.
