Abstract:
Disclosed are a corer and a method using same. The corer includes a connecting sleeve, a power lever connected to the connecting sleeve, a hook cylinder having an upper end inserted into the connecting sleeve, and a cutting hook connected to a side of the hook cylinder. A full-length opening is vertically formed on a side wall of the hook cylinder. The upper end of the hook cylinder is detachably connected to the connecting sleeve. An arc slot perpendicular to the full-length opening is provided on a side of a lower end of the hook cylinder. The corer solves the problem that the existing corer is unable to extract an intact core because it is unable to transect a core base during non-penetrating coring.

Claim (Index 6):
The corer of  claim 1 , wherein a plurality of connecting holes spaced apart are horizontally arranged on the lower portion of the connecting sleeve along a circumferential direction and penetrate through the fastener;\n a through slot passing through the cutting hook is vertically provided on the side wall of the lower portion, corresponding to the opening of the hook cylinder; an annular slot is provided at a lower opening of the lower portion of the connecting sleeve along a circumferential direction; the hook cylinder is inserted into the annular slot; a width of the annular slot is adapted to a wall thickness of the hook cylinder; and a middle of the lower portion of the connecting sleeve is in a threaded connection with a power lever.
