This invention discloses a core retrieval or recovery tool for drilling, relating to the field of drilling engineering technology. The internal drill string assembly is suspended within the central channel of the external drill string assembly via a centralizer. The lower end of the internal assembly is a retaining spring assembly, and the lower end of the external assembly comprises the drill bit and multiple sliding blocks. One end of each sliding block extends into one end of the drill bit and is suspended by an elastic element. One end of the retaining spring assembly passes through the drill bit and extends between the sliding blocks, with the outer wall of the retaining spring assembly engaging with the inner wall of each sliding block via a bevel. Drilling fluid is introduced into the internal drill string assembly, causing it to move downwards relative to the external assembly. The downward movement of the retaining spring assembly pushes the sliding blocks outwards away from the drill bit's centerline. When the internal drill string assembly resets, the elastic element drives the sliding blocks back towards the drill bit's centerline. This invention improves drill string throughput and prevents the loss of incomplete or fragmented core samples at the drill bit, thereby increasing the core retrieval rate or core recovery rate.
