Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

The left end of the threaded main shaft 1 is detachably connected with an external drill rod thread of a drilling machine to drive the threaded main shaft 1 to rotate; the right end of the threaded spindle 1 is connected with a transfer case 6 (a bearing chamber), a protective tube ring 15 is sleeved on the outer wall of the coaxial transfer case 6, and a male pull nose 7 is arranged on the right side of the transfer case 6; the female pull nose 8 is arranged at the left end of the pull rod 11, the male pull nose 7 and the female pull nose 8 are connected together in a matching way, the concave-convex shaft 13 is connected with the right end of the coaxial pull rod 11, and the output end of the oil cylinder 14 is connected with the right end of the concave-convex shaft 13;

as shown in fig. 2, the threaded spindle 1 is provided with three groups of array claw wheels with gradually increasing diameters from left to right, each group of array claw wheels comprises a plurality of claw wheel sets 2 in an annular array with the threaded spindle 1, and the diameters formed by the plurality of annular array claw wheel sets 2 arranged from left to right are sequentially increased;
