Then, the screw-off rotation rod connecting core rod 11 is rotated to break the screw connection with the retractable rotation rod 8 of the sampling tube, and the rotation rod connecting core rod 11 is taken out from the core rod insertion hole 13 of the handle insertion rod 3 (as shown in fig. 14). Then, the handle inserted rod 3 is pulled out reversely by the material taking operation handle 4, so that the middle layer cutting cylinder body 9 and the inner layer material taking cylinder body 6 which are connected into a whole are pulled by the cutting cylinder telescopic tube 10 connected with the handle inserted rod 3 to retract into the material taking closed cavity 5 of the outer layer closed cylinder body 1 together (as shown in fig. 15). Then, the material taking operation handle 4 and the handle inserted bar 3 are turned and unscrewed to disconnect the threaded connection with the cutting barrel telescopic pipe 10, and the handle inserted bar 3 is taken out from the inserted bar telescopic cavity 2; and then the inserting rod inlet and outlet 34 and the closed opening 33 at the two ends of the outer layer closed cylinder 1 are respectively sealed by using the inserting rod opening plug 44 and the closed opening plug 45 (as shown in figure 16), so that the totally-closed transfer from the collection of the dead body to the operation of the laboratory on the material to be detected in the whole process is ensured.
