description The utility model relates to the technical field of tree ring sampling tools, in particular to an auxiliary pulling-out device for a growth cone, which comprises a pushing rotary sleeve, a pulling seat sleeve, an elastic wedge claw block and a locking pressing sleeve, the pushing rotary sleeve is cylindrical, a rotary sleeve internal thread is arranged on the inner wall of the pushing rotary sleeve, and a rotary sleeve handle is arranged at the lower end of the outer side of the pushing rotary sleeve. The drawing seat sleeve comprises a seat sleeve body section, a drawing cylinder section and a lock sleeve mounting section. The drill rod pulling device is reasonable and compact in structure and convenient to use, the elastic wedge claw block can firmly and reliably lock a drill rod, the stress portion of the drill rod pulling device is large and gentle in stress when the drill rod is pulled out, the pushing rotary sleeve is rotated to drive the pulling seat sleeve to move to pull out the drill rod, the drill
