The relative position of ascending pipe；Then being injected by ascending pipe in human body bone, another hands press sleeve connecting handle, due to through-hole wall
The second female thread and the second external screw thread threaded so that tamper assembly along hand of helix rotate glide, in order to by required
Artificial bone, allograph bone or the autologous bone implanted are compacted at the position wanting bone grafting, and due to the existence of spring, cover assembly can be subject to all the time
To downward elastic force, it is fixed on funnel port and the movement along tamper pole length direction does not occur, simultaneously because unidirectional latch is subject to
The restriction of the second dop, makes cover assembly keep geo-stationary with funnel；When tamper body lower end and osteomiosis are again without active force, will be by
The hands of gland T-Ring unclamps to be held tamper bar simultaneously and is allowed to not rotate, and is merely lifted up by tamper bar, due to through hole
Second female thread of inwall is threadeded with the second external screw thread of tamper assembly, and due to the most unidirectional latch not by the second dop
Restriction, cover assembly can rotate relative to stamp stem, drive plectrum rotate relative to funnel so that the broken bone being attached to inner wall of hopper exists
Move in the middle of funnel under the promotion of plectrum, eventually fall in ascending pipe；Repeat the above steps, it becomes possible to be easily accomplished bone grafting hands
