For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] like Figures 1 to 3 As shown, a rotary intestine picking needle according to a preferred embodiment of an embodiment of the present invention comprises a sleeve 10 and at least one rotary slide rod 20. The sleeve 10 is provided with mounting through holes corresponding to the number of the rotary slide rods 20 and opened along its axial direction. The rotary slide rod 20 is coaxially penetrated in the mounting through holes. The outer peripheral wall of the rotary slide rod 20 is provided with a transverse pin 21 protruding along its radial direction. The outer peripheral wall of the sleeve 10 is provided with a spiral guide groove 11. The transverse pin 21 penetrates the spiral guide groove 11 and can slide along the spiral guide groove 11. The end of the rotary slide rod 20 is provided with a hook needle 30 for hooking shrimp intestines.

[0030] like Figure 3 As shown, in Figure 3The working process of the rotary intestine picking needle rotating to pick shrimp intestines is shown in the figure in sequence according to steps A to E. In a rotary intestine picking needle of the present invention, Figure 3 In step A, by lifting the sliding sleeve 10, the entire rotating intestine picking needle is suspended, the cross pin 21 is located at the lower end of the spiral guide groove 11, and the hook body 32 of the hook needle 30 is placed roughly perpendicular to the extension direction of the shrimp intestine 41. Figure 3 In steps B-C, when the sliding sleeve 10 is pressed down, the hook needle 30 is blocked when inserting into the shrimp body 40, so that the cross pin 21 slides upward to the top of the spiral guide groove 11, thereby driving the hook needle 30 to rotate to a direction substantially parallel to the extension direction of the shrimp intestine 41 and away from the shrimp intestine 41. By further pressing down the sliding sleeve 10, the cross pin 21 hits the top of the spiral guide groove 11, so that the hook needle 30 is inserted into the shrimp body 40. Figure 3 In steps C-D, when the sliding sleeve 10 is lifted, the cross pin 21 gradually slides down along the spiral guide groove 11 and drives the hook 30 to rotate close to the shrimp intestine 41 and below the shrimp intestine 41. Figure 3 In steps D-E, when the cross pin 21 slides to the bottom end of the spiral guide groove 11, the hook hook 30 is fixed and does not rotate further. When the sliding sleeve 10 is further lifted, the shrimp intestine 41 is located in the hook hook 30 and moves out of the shrimp body 40 together with the hook hook 30. Since only the hook hook 30 is inserted into the shrimp body 40 and forms an outlet for the shrimp intestine 41, the damage to the shrimp body 40 is small and the shrimp appearance is highly intact.

[0031] Furthermore, the central angle of the arc length of the orthographic projection formed by the spiral guide groove 11 along the axial direction of the sliding sleeve 10 is 90°. When the rotation angle range of the rotating slide bar 20 is 0°-90°, the extension direction of the hook body 32 of the hook needle 30 is parallel to the extension direction of the shrimp intestine 41, and the hook needle 30 is inserted into the shrimp body 40 to avoid contact with the shrimp intestine 41 and cut off the shrimp intestine 41. When the hook needle 30 is rotated and located below the shrimp intestine 41, the extension direction of the hook body 32 of the hook needle 30 is perpendicular to the extension direction of the shrimp intestine 41, which can increase the probability of the shrimp intestine 41 being located inside the hook body 32, thereby increasing the probability of successfully pulling out the shrimp intestine 41.

[0032] Furthermore, the hook needle 30 includes a hook rod 31 and a hook body 32 extending obliquely upward from the bottom end of the hook rod 31, and a hook groove 35 is defined between the top surface of the hook body 32 and the hook rod 31. When the shrimp intestine 41 is pulled up, the shrimp intestine 41 slides along the top surface of the hook body 32 to the hook groove 35. Since the hook groove 35 is recessed downward, it is convenient to fix the shrimp intestine 41 in the hook groove 35, so that the shrimp intestine 41 can be pulled out easily.

[0033] Furthermore, the bottom of the hook body 32 is provided with a blade 33 formed by the intersection of two planes in a straight line, and the lowermost end of the blade 33 is provided with a sharp spike 34 with a thin end. The sharp spike 34 located at the lowermost end of the hook needle 30 and having a thin end is more convenient for piercing the shrimp body 40, forming a small opening in the shrimp body 40, and then further cutting the shrimp body 40 through the sharp blade 33, so that the hook needle 30 can be smoothly inserted into the shrimp body 40.

[0034] Furthermore, the hook 30 is inserted into the shrimp body 40 to pick out the intestines. The hook 30 is flat as a whole, which can reduce damage to the shrimp body 40 and maintain the complete appearance of the shrimp body 40.

[0035] Furthermore, the top surface of the hook body 32 and the side surface of the hook rod 31 facing the hook body 32 are both flat or arc surfaces, which can avoid cutting or hooking the shrimp intestine 41.

[0036] Further, such as Figure 1 As shown, the rotating slide bar 20 includes a rod body 22, a connecting portion 23 and a hook 30. The rod body 22 is a cylinder. The connecting portion 23 is located between the rod body 22 and the hook 30. The upper end of the connecting portion 23 is circular and matches the shape of the rod body 22 and is connected. The lower end of the connecting portion 23 is flat and is connected to the upper end of the hook rod 31. Since the rotating slide bar 20 needs to meet the functions of rotating and inserting the shrimp body 40, the rod body 22 of the rotating slide bar 20 needs to be cylindrical to meet the needs of rotation, and the hook 30 is flat to meet the needs of reducing damage to the shrimp body 40 and keeping the shrimp body 40 intact in appearance. The rod body 22 with different shapes is connected to the hook 30 through the connecting portion 23 to improve the consistency of the appearance of the rotating slide bar 20.

[0037] Furthermore, the cross pin 21 is cylindrical, and arc-shaped ends 12 are respectively provided at both ends of the spiral guide groove 11, and the radius of the arc-shaped end 12 matches the radius of the cross pin 21, thereby improving the cooperation between the arc-shaped end 12 and the cross pin 21. The cross pin 21 is cylindrical, and the outer peripheral wall is overall continuous and smooth without edges and corners, so that the cross pin 21 slides more smoothly in the spiral guide groove 11.

[0038] Specifically, Figure 2 As shown, the rotary intestinal needle includes a mounting cover 13, a mounting groove is provided in the axial direction of the sliding sleeve 10, the mounting groove is connected to the mounting through hole, and the mounting cover 13 is detachably mounted in the mounting groove. The rotating slide rod 20 is inserted through the mounting through groove and moved into the mounting through hole, the cross pin 21 is installed in the spiral guide groove 11, and then the mounting cover 13 is installed in the mounting groove. The detachable installation includes but is not limited to screw hole screw matching installation, snap-on installation and the like.

[0039] Further, another embodiment of the rotary intestinal needle of the present invention is as follows Figure 4 - Figure 5As shown, there are two rotating slide bars 20, which are symmetrically arranged. When the two rotating slide bars 20 rotate until the hooks 30 face each other, the hooks 30 of the two groups of rotating slide bars 20 are staggered. Specifically, the sliding sleeve 10 includes a first sliding sleeve 14 and a second sliding sleeve 15. The first sliding sleeve 14 and the second sliding sleeve 15 can be combined in an integrated manner or in a detachable manner. Figure 5 As shown, in Figure 5 The working process of the rotary intestine picking needle of this embodiment is shown in steps A to E. The working process of the rotary intestine picking needle of this embodiment is as follows: Figure 5 As shown in steps A-B in the figure, the shrimp body 40 is uprighted with its back facing upward, and the two groups of hook needles 30 are inserted downward into the shrimp body 40. The two groups of hook needles 30 cannot be inserted immediately due to the resistance of the shrimp body 40. The sliding sleeve 10 is pressed down, and the two groups of cross pins 21 slide to the top of the two groups of spiral guide grooves 11 respectively and drive the rotating slide rod 20 to rotate respectively, so that the two groups of hook needles 30 rotate away from the shrimp intestine 41 and remain roughly parallel to the shrimp intestine 41. The sliding sleeve 10 is further pressed downward so that the two groups of hook needles 30 are inserted into the shrimp body 40; Figure 5 As shown in steps C-D in the figure, the sliding sleeve 10 is lifted up, and the two sets of cross pins 21 slide from the top to the bottom along the spiral guide groove 11 and respectively drive the rotating slide bar 20 to rotate, so that the two sets of hook needles 30 rotate to the corresponding lower part of the shrimp intestine 41, and the hook bodies 32 of the two hook needles 30 are turned to the direction of the shrimp intestine 41. Since the hook bodies 32 of the two sets of hook needles 30 are in contact, the two sets of hook bodies 32 form a closed cavity between the two sets of rotating slide bars 20, ensuring that the shrimp intestine 41 is located in the closed cavity, preventing the shrimp intestine 41 from being located outside the hook needle 30, and keeping the shrimp intestine 41 in one of the hook needles 30. Figure 5 As shown in step E in the figure, the sliding sleeve 10 is further lifted, and the shrimp intestine 41 is lifted along with the hook needle 30, and the hook needle 30 hooks the shrimp intestine 41, and the shrimp intestine 41 is hooked out of the shrimp body 40. This embodiment also reduces the degree of damage to the shrimp body 40 and can keep the shrimp appearance intact, while also increasing the probability of successfully removing the shrimp intestine 41.

[0040] In summary, an embodiment of the present invention provides a rotating intestine picking needle, which realizes the rotation control of the hook needle 30 by the sliding of the cross pin 21 along the spiral guide groove 11, so that the hook needle 30 can be moved away from or close to the shrimp intestine 41. At the same time, the hook needle 30 pierces the shrimp body 40 to form a pulling outlet for the shrimp intestine 41, thereby achieving the purpose of minimizing the damage to the shrimp body 40 and maintaining the integrity of the shrimp appearance.

[0041] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
