3. The bin clamping device according to claim 1, wherein each bin body is provided with a rack plate matched with external force, and the external force pushes the rack plate to move so as to push the bin body to move.

4. The bin clamping device according to claim 3, wherein two ends of each bin body are respectively provided with a first hook and a first groove matched with the first hook, and each two adjacent bin bodies are dislocated under the pushing of an external force and then are clamped with the first grooves through the first hooks to realize connection.

5. The cartridge device of claim 1, wherein said first cartridge body and said ligating clip form a first cartridge assembly, said first cartridge assembly at a forward most side further comprising a clamp connected to said cartridge body.

6. The bin clamping device according to claim 1, wherein each of the pushing and clamping assemblies includes a moving member that moves relative to the bin body under an external force and a pushing and clamping piece that is pushed by the moving member to move forward relative to the bin body, two adjacent moving members are fixedly clamped after being unfolded, at least two first slots are formed in the pushing and clamping piece, a first ratchet that is used for supporting the first slots to push the pushing and clamping piece to move forward relative to the bin body is formed in the moving member, a stopping structure is formed between the bin body and the pushing and clamping piece, and when the moving member is pulled back by the external force, the moving member can move backward relative to the pushing and clamping piece and the stopping structure supports the pushing and clamping piece to prevent the pushing and clamping piece from moving backward relative to the bin body.

7. The cartridge device of claim 6, wherein the stop structure comprises a second ratchet and a second slot parallel to and offset from the first slot, the second slot being disposed on one of the cartridge body and the push-clip tab, the second ratchet being disposed on the other of the cartridge body and the push-clip tab.

8. The cartridge device of claim 1, wherein only the push-clip assembly is disposed within the second cartridge body, the second cartridge body and the push-clip assembly forming a second cartridge assembly.

9. The cartridge clamping device of claim 1, wherein said cartridge body further comprises a third cartridge body disposed between said first cartridge body and said second cartridge body, said third cartridge body being disposed between and connecting said first cartridge body and said second cartridge body after deployment, said third cartridge body forming a third cartridge clamping assembly with said ligating clip and said clip pushing assembly.

10. The cartridge device of claim 1, wherein said cartridge body further comprises a fourth cartridge body disposed on a top layer, said fourth cartridge body is located at a rear side of said second cartridge body after being deployed, said cartridge device further comprises a push rod disposed in one of said cartridge bodies and connected to said push-clamp assembly, said fourth cartridge body, said push-clamp assembly and said push rod form a fourth cartridge assembly.

11. The cartridge device according to claim 10, wherein a first pushing block and a second pushing block are further disposed in the cartridge housing, the first pushing block is fixedly disposed on one side of the pushing rod, the second pushing block is slidably disposed on the pushing rod, and the first pushing block and the second pushing block are both provided with engaging teeth.

12. A surgical instrument, comprising a holding portion provided with a driving device and a working portion connected to the holding portion, wherein the working portion comprises a housing formed with an inner cavity, a firing force application member arranged in the inner cavity and connected to the driving device, a firing sleeve connected to the firing force application member, and the cartridge device according to any one of claims 1 to 11 driven by the driving device; and a mounting opening is formed in a shell on one side of the cavity, and the bin clamping device is detachably connected with the working part through the mounting opening.
