[0038] The connecting rod locking assembly 4 has a self-locking function, which realizes the stable locking of the sample core tubes 3 by the locking plate 5.

[0039] As Figure 2As shown in the figure, the connecting rod locking assembly 4 includes an outer peripheral fixed support frame 41, a moving support frame 42, two connecting rods A 43, two connecting rods B 44, two connecting rods C 45 and a slide rod 46.

Further, the whole of the moving plate 6 and the locking plate 5 moves up and down along the support rod around the base plate 1 to realize the locking and fixing of the sample coring tube 3 at multiple positions up and down.
