    摘要： The present invention relates to a borehole drilling apparatus with in-line extending wings and driving method thereof. The drilling apparatus comprises a guide device rotating while moving upwardly and downwardly in a casing to fit into aborehole, extending wings for exterκling the diameter of adriUedhole, arκiapUotbitinstelledatalowerportionofthe guide deviceto strike the bottom of the borehole, wherein spiral projections formed at a lower surface of tiie guide device slidably engage with guide grooves formed at a side of the extending wings to each other, and a window is formed at a side of Hie pilot bit for advancing and retracting the extending wings so that they can spread and return linearly from the center of the pilot bit

    摘要： The present invention relates to a fluid-operated percussion drill tool (1) comprising an outer wear sleeve (2) comprising a substantially cylindrical wall (3) and having inner (4) and outer (5) surfaces. The tool also comprises a percussion bit (6) having a head portion (7) and a bit retaining portion (8) and located at a forward end (9) of the outer wear sleeve. The tool further comprises a sliding piston (10) mounted for reciprocating movement within the outer wear sleeve to strike the percussion bit. The tool also includes a drive ring (11) having a substantially cylindrical wall (12) and comprising connection means (13) adapted for connecting the drive ring to a drive means of the fluid-operated percussion drill tool. At least one flushing channel (31) provides a fluid path to the cutting face of the bit for a flushing medium. A first portion (32) of the at least one flushing channel extends longitudinally within the wall (3) of the wear sleeve, a second portion (36) of the at least one flushing channel extends longitudinally within the wall (12) of the drive ring and a third portion (40) of the at least one flushing channel extends through the head portion (7) of the percussion bit to the cutting face (43) of the bit.
