The electric auxiliary pressure plate 6 below upper clamping plate 5 has a built-in telescopic motor to fix the fish in place. The centering shell 7 consists of two racks and a moving gear. The racks are fixed to lower clamping plate 3 and electric auxiliary pressure plate 6 respectively, and the moving gear is in the middle. When the racks move, the meshing action keeps the moving gear in the center position. The extended crossbar of the moving gear drives to the reference electric control 8. Corresponding to the internal position of the reference electric control 8, the lifting platform 15 is raised and lowered to find the reference position, which makes it easier to find the center position of the fish and cut the fish belly.

[0038] The reference frame 13 provides a reference position for processing fish, and the camera 14 facilitates the image capture and analysis of fish.
[0039] Reference Figure 1-4 The upper surface of the working plate 1 is provided with a lifting platform 15, and the outer surface of the output end of the lifting platform 15 is provided with a telescopic motor 16.
[0040] The lifting platform 15 uses a motor to lift and lower the working parts as a whole, and the telescopic motor 16 makes it easy to extend and retract to insert into the fish's belly.

After the external expansion motor 18 picks up the fish offal, the second cutting blade 19 interacts with the external expansion motor 18 from behind to cut the inside of the fish, causing the fish meat and fish offal to separate.
[0043] Reference Figure 1-4 A reference plate 20 is welded to the upper surface of the working plate 1, and an adjusting plate 21 is movably connected to the inner surface of the reference plate 20.

The motor 9 drives the movable shaft 4, causing the lower clamping plate 3 and the movable shaft 4 to open and close, squeezing the fish head. The electric auxiliary pressure plate 6 below the upper clamping plate 5 has a built-in telescopic motor that holds the fish in place. The outer shell 7 is made of a soft, deformable material and consists of two racks and a moving gear. The racks are fixed to the lower clamping plate 3 and the electric auxiliary pressure plate 6, with the moving gear in the middle. When the racks move... The meshing action keeps the moving gear in the center position, and the extended crossbar of the moving gear drives the reference electric control 8. Corresponding to the internal position of the reference electric control 8, the lifting platform 15 is raised and lowered to find the reference position, which makes it easier to find the center position of the fish and cut the fish belly. The lower clamping plate 3 and the movable shaft 4 squeeze and fix the fish head, the cylinder 11 retracts, and the telescopic motor 16 extends forward respectively corresponding to the position of the fish belly. The cutting blade 17 cuts open the fish belly, and the second outward expansion motor 18 enters to expand up and down to open the fish belly. At the same time, the fish offal is clamped in the corresponding position. The second cutting blade 19 cuts the inside of the fish, and the whole process drives the fish meat and fish offal to be separated. The lifting motor 24 lowers the carrier plate 12 and tilts, and the fish offal falls into the collection box 23 by gravity.
