[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Through the above technical solution: when in use, the connecting block 7 of another shell body 4 is embedded into the connecting groove 5 on the current shell body 4, so that the connecting block 7 is embedded in the connecting groove 5, and the two shell bodies 4 are spliced ​​and fixed by using the interlocking connection between the card slot 10 and the card strip 1, and then the above operation is repeated to splice multiple shell bodies 4, and multiple shell bodies 4 are spliced, thereby expanding the overall caliber of the shell body 4, solving the problem of the current single-caliber biological filler having large limitations in use. At the same time, since the connecting groove 5 and the card strip 1 are both trapezoidal structures, they intersect at right angles, which improves the efficiency of subsequent disassembly.

[0020] See also Figure 1-Figure 3 As shown, a through hole 3 is provided in the middle of the surface of the partition plate 2, a threaded groove 6 is provided at one end of the inner wall of the through hole 3, a threaded tube 9 is installed in the middle of the side of the partition plate 2 away from the threaded groove 6, the diameter of the threaded tube 9 is smaller than the diameter of the threaded groove 6, an auxiliary groove 11 is symmetrically provided on the outer wall surface of the shell body 4 and located between the connecting block 7 and the connecting groove 5, the auxiliary groove 11 is an arc-shaped groove, and ridges 8 are symmetrically installed at equal intervals on both sides of the inner wall of the partition plate 2.

[0021] Through the above technical solution: when adjusting the thickness, the two shell bodies 4 are stacked up and down so that the threaded tube 9 and the threaded groove 6 are kept on the same axis, and then the threaded tube 9 is embedded into the threaded groove 6 by rotating the shell body 4, and the two shell bodies 4 are fixed by the threaded connection between the threaded groove 6 and the threaded tube 9, thereby achieving the purpose of increasing the thickness of the shell body 4. After the thickness increase is completed, the two stacked shell bodies 4 can also be adjusted so that their end faces remain consistent and level.
