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 1):
A corer, comprising:\n 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; wherein a full-length opening is vertically formed on a side wall of the hook cylinder; an upper end of the hook cylinder is detachably connected to the connecting sleeve, and an arc slot perpendicular to the full-length opening is provided on a side of a lower end of the hook cylinder; and a plurality of teeth are arranged on a lower end surface of the hook cylinder along a circumferential direction; a cross section of the hook cylinder at both sides of the opening on the side wall is an arc surface; the cross section of the hook cylinder is fitted with a circular cross section of the connecting rod of the cutting hook; a radian of the cross section of the hook cylinder is consistent with a radian of an arc of an outer wall of the connecting rod of the cutting hook; the connecting sleeve is a funnel-shaped cylinder which comprises a cylindrical upper portion, a conical connecting portion and a cylindrical lower portion; a set of clamping slots are provided on an inner side surface, corresponding to an opening of the hook cylinder, of an upper portion of the connecting sleeve; the clamping slots are configured to clamp a handle of the cutting hook; an included angle between the clamping slots is 10-25 degrees; and a pair of bolt holes is symmetrically provided on a side wall of the upper portion of the connecting sleeve; a plurality of bolts for rotating the connecting sleeve are arranged in the bolt holes.
