The drilling tool comprises a drill rod 24, a pipe joint 25, a core barrel 26, a straight joint 27, a clamping spring 28 and a drill bit 29 which are coaxially arranged. With the drilling direction of the drill bit 29 as the front, the rear end of the drill rod 24 is in threaded connection with the mandrel 19, the front end of the drill rod 24 is in threaded connection with the rear end of the core barrel 26 through the pipe joint 25, and the front end of the core barrel 26 is in threaded connection with the drill bit 29 through the through joint 27. The drill bit 29 is an integrated structure formed by hot-pressing a drill bit steel body 32 at the rear end and a diamond matrix 33 at the front end, wherein the inner wall at the rear end of the drill bit steel body 32 is in threaded connection with the front end of the straight joint 27, the inner wall at the front end is provided with an inverted conical surface 31, the minimum inner diameter of the inverted conical surface 31 is larger than the inner diameter of the diamond matrix 33, and the maximum inner diameter is the aperture of the inner wall of the drill bit steel body 32.

In the application, the extrusion state of the clamp spring 28 refers to a free state of the clamp spring 28 without being stressed, and the expansion state of the clamp spring 28 refers to a state that a rock core passes through the clamp spring 28 to expand outwards.

After drilling, when the drilling tool is lifted upwards, the clamp spring 28 moves towards the inverted conical surface 31 due to friction force with the rock core, the inner diameter and the outer diameter are reduced under the extrusion of the inverted conical surface 31 to achieve the state of clamping the rock core, the drilling tool is slightly rotated at the moment, the rock core is clamped by the clamp spring 28, and the clamp spring 28 cannot be pulled out from the drill bit steel body 27, so that one-time operation of drilling and taking the rock core can be completed.
