The lobster is placed on the clamping component on the device, the shrimp head is located in the first clamping component 3, and the shrimp tail is located in the second clamping component 4. After arranging multiple lobsters at a time, the first clamping component 3 and the second clamping component 4 are operated, and the two clamping components are used to clamp the head and tail of the lobster respectively, and then the second clamping component 4 is moved in the direction away from the first clamping component 3. The second clamping component 4 moves relatively through the connecting component 5 until the head and tail of the lobster are separated. Then, after loosening the two clamping components, the clamping components open, the head and tail of the lobster are removed, and subsequent operations can be performed.

The first follower plate 501 and the second follower plate 503 are respectively installed on the first clamping component 3 and the second clamping component 4. The waist-shaped hole 502 is opened on the first follower plate 501, the follower rod 504 is fixedly connected with the connecting head 505, and the follower rod 504 is installed on the second follower plate 503. The follower rod 504 passes through the waist-shaped hole 502, and the nut 506 is installed on the connecting head 505. By setting the first clamping component 3 and the second clamping component 4, the shrimp head and the shrimp tail can be effectively clamped. Clamping ensures the normal progress of the separation work. A reset spring 308 is set in the first clamping component 3, which can open the first clamping plate 301 and the second clamping plate 302 after the lobster head and tail are separated, so as to facilitate the removal of the shrimp head for subsequent operations. A rubber plate 403 is set in the second clamping component 4, which can provide a certain protection for the shrimp tail part while clamping the shrimp tail, so as to avoid the breakage of the shrimp tail caused by excessive clamping force, thereby ensuring the integrity of the shrimp tail. The second clamping component 4 is connected to the first clamping component 3 through the connecting component 5. The two clamping components will not interfere with each other during the clamping process. In the process of opening the first clamping component 3, the clamping plates in the second clamping component 4 can be separated through the connecting component 5. The structure is simple and the use effect is excellent.

[0021] When the lobster is clamped, the shrimp head is located between the first clamping plate 301 and the second clamping plate 302, and the shrimp tail is located between the third clamping plate 401 and the fourth clamping plate 402. A force is applied to the two clamping components, and the first clamping plate 301 moves along the guide rod 306 on the first connecting block 304 through the second connecting block 305 until the clamping plate firmly clamps the shrimp head with the teeth 303. At this time, the reset spring 308 is in a compressed state, and for the clamping work of the shrimp tail, the fourth clamping plate 402 and the fourth clamping plate 402 are in a compressed state. The three clamping plates 401 are brought together, and the fourth connecting block 405 moves along the movable rod 406 on the third connecting block 404 until the lobster tail is clamped and fixed by the rubber plate 403. In this process, the moving stroke of the second clamping assembly 4 is different from the moving stroke of the first clamping assembly 3. The second follower plate 503 moves with the follower rod 504 relative to the first follower plate 501, and the follower rod 504 moves in the waist-shaped hole 502. When the lobster head and tail are clamped, the second clamping assembly 4 The lobster tail is pulled to separate the head and tail of the lobster. The follower rod 504 still moves in the waist-shaped hole 502, which will not affect the normal movement of the clamping assembly. When the head and tail of the lobster are separated, the clamping assembly is released, and under the action of the reset spring 308, the first clamping plate 301 and the second clamping plate 302 are opened. In this process, the limit block 309 on the stud 307 plays a limiting role, preventing the first clamping plate 301 from being completely separated from the second clamping plate 302, and the first clamping plate 301 and the second clamping plate 302 are opened. During the separation process of 302, the first follower plate 501 will be moved with it. When the end of the waist-shaped hole 502 contacts the follower rod 504, a force is exerted on the follower rod 504, thereby separating and opening the third clamping plate 401 and the fourth clamping plate 402 through the connecting component 5. The stopper 408 on the threaded joint 407 plays a limiting blocking role to prevent the third clamping plate 401 and the fourth clamping plate 402 from separating. The above process is repeated to continuously separate the head and tail of the lobster.
