The utility model discloses a drilling tool fisher for high-pressure rotary jet grouting construction. A slip bowl 2 is mounted at the front end of a shell assembly welding piece 1; a guide joint 5 is mounted at the front end of the slip bowl 2; an embedded slip 6 is mounted on the slip seat 2 in a clamping and sliding manner; an extension spring assembly 7 is arranged between the embedded slip 6 and the shell installing and welding piece 1; a flange joint 3 is mounted at the rear end of the shell welding assembly 1; and the lifting joint 4 is mounted at the rear end of the flange joint 3. According to the device, the difficulty of fishing the drilling tool by a construction side is reduced, the treatment effect of the drilling tool falling off in the hole is improved, and the fishing success rate is improved by means of the device instead of manual experience exploration fishing. And in addition, the fishing cost is reduced, the drilling tool is effectively protected, and the requirements of environment-frie
