[0030] Working principle: first place the device in a suitable position so that the clamping assembly of the device is away from the operator, hold the head shell and claws of the crayfish with your hands, so that the crayfish's tail faces outward and the crayfish's abdomen faces downward, and then insert the crayfish vertically from top to bottom along the guide assembly onto the vertical rod 9. Since the crayfish's abdomen faces downward, the smooth head shell is prevented from directly contacting the vertical rod 9 first, making it easier for the vertical rod 9 to quickly penetrate the crayfish's head shell, and then the crayfish can be stably fixed on the vertical rod 9; then move the crayfish down so that the tail falls in the middle of the clamping assembly, start the double-headed motor 18, and simultaneously drive the output shafts and the screw rod 19 on both sides to rotate, and then simultaneously The internal threaded sleeves 20 on both sides are driven to move toward the middle, and then the connecting rod 22 is driven through the connecting plate 21, thereby driving the connecting plates 16 and the clamping plates 17 on both sides to move toward the middle and clamp them on both sides of the shrimp tail so as to quickly fix the shrimp tail. Then the driving assembly is started, and the telescopic rod of the electric push rod 11 pushes the rack 12 to one side, thereby pushing the gear 13 to rotate. The gear 13 drives the clamping assembly to rotate through the rotating shaft 14, providing rotational power to the clamping assembly. After that, the clamping assembly moves in the opposite direction to release the shrimp tail, so that the shrimp tail can be quickly obtained without manual twisting to separate the head shell and the shrimp tail, effectively avoiding fingers being pierced by the crayfish shell. In addition, after the head shell and the shrimp tail are separated, the vertical rod 9 is driven by the electric push rod 23 to move down and retract into the vertical slot. At this time, the vertical rod 9 is disengaged from the middle hole of the support plate 8 at the same time. Then the telescopic rod of the electric push rod 23 continues to move down, driving the pressure plate 27 to press the movable plate 26, so that the movable plate 26 moves down along the movable cavity, and then the support plate 8 is pulled to the side away from the clamping assembly by the pull rope 25, so that the head shell slides to one side, which is convenient for quickly removing the head shell. After that, the electric push rod 23, the spring 2, the torsion spring and other structures are reset to reset the related structures, so that the next crayfish can be processed conveniently; and the head shell falls to one side of the mounting platform 3, and the shrimp tail falls to the other side of the mounting platform 3, so that the head shell and the shrimp tail are quickly separated, which is convenient for use; When the pull rope 25 is pulled down, the push plate 29 is pulled to rotate to both sides, thereby pushing the guide plates 6 on both sides to move to both sides, so that the guide plates 6 no longer clamp the head shell, allowing the head shell to easily slide along the support plate 8.
