The length of the limiting groove 224 is not less than one third of the length of the propping part 132, so as to avoid the extrusion of the fixed claws on the nested fixed pipe.
Further, a primary guide pipe is further arranged on the inner wall of the nested fixed pipe 22 close to one end of the first long threaded anchor bar 11, and the primary guide pipe is composed of a round pipe 221 and a conical pipe 222 which are connected in sequence.
