description	The utility model provides a sampling device, which belongs to the technical field of sampling devices and comprises a sampling barrel and a pointed end, when the pointed end is mounted, the surface of a locking groove in contact with a clamping tongue first is an arc surface or an inclined surface, when the pointed end is mounted, the surface of the locking groove in contact with the clamping tongue later is a straight surface, and a pull rope is arranged on the clamping tongue. The utility model has the beneficial effects that after long-time use, the pull rope is pulled to enable the clamping tongue to overcome the resistance of the elastic piece, the clamping tongue is not locked by the locking groove, the tip is taken off at the moment, when a new tip is required to be installed, the limiting column corresponds to the limiting groove, then the tip is pressed forcibly, the clamping tongue is extruded, the inclined surface of the clamping tongue is subjected to a horizontal component force, and the tip can
