Description

Technical Field

[0001] This utility model relates to the field of fish head segmentation technology, specifically a positioning tool for segmenting and positioning black carp heads. Background Technology

[0002] The snakehead head splitting and positioning knife is a professional tool designed for efficiently and safely splitting hard fish heads (such as snakehead and grass carp). The core is to solve the problems of strength, accuracy and safety. The special heavy-duty chopping knife, such as the fish head cutter / salmon cutter, uses a thick high-carbon steel blade, non-slip handle and protective guard. It emphasizes the downward chopping force and anti-slip design to ensure consistent cutting position, neat cut, effortless operation, and keeps the hand away from the blade path, greatly reducing the risk of cuts and easily splitting the hard snakehead skull.

[0003] Currently, traditional black carp head cutting tools cut by inserting the fish head into a guide cone for cutting, and require the operator to hold the fish tail by hand. In this way, the fish head may slip off, which may injure the operator. In view of this, this utility model provides a fish head cutting tool with fixed positioning. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a black carp head segmentation and positioning tool to solve the technical problem that the fish head is easy to slip off with traditional tools.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a black carp head segmentation and positioning tool, comprising a tool, a base plate on the tool, a support plate fixedly connected above the base plate, a guide cone fixedly connected to one side of the support plate, a placement frame fixedly connected to the support plate below the outer periphery of the guide cone, the placement frame being 'C' shaped, gaps forming between the placement frame, the guide cone, and the support plate, the placement frame including a placement frame base plate, and two sets of hooks fixed to the support plate above the guide cone, one side of each hook being pointed, the hooks being used for positioning and fixing the fish head.

[0006] By adopting the above technical solution, the conical structure of the guide cone enables the top of the fish head to be quickly centered and positioned, greatly improving the initial placement efficiency; after the two sets of pointed hooks penetrate the hard bone tissue of the fish head, they form an axial lock, completely eliminating the risk of dislocation of the fish head caused by chopping vibration in traditional methods. At the same time, the 'C'-shaped placement rack provides a U-shaped support surface for the fish body, and the gap formed by the support plate and the guide cone together creates a three-dimensional limiting space, ensuring that the fish head is always in the center of the cutting path; this structure allows the operator's hands to be completely removed from the fish body, fundamentally eliminating the possibility of accidental hand injury by the knife.

[0007] Furthermore, the inner side of the base plate of the placement rack is inclined, and the lower side of the base plate is close to the gap.

[0008] By adopting the above technical solution, the inner inclined surface design of the base plate of the placement rack forms a sliding rail structure that slopes from the outside to the inside. When the fish is placed on the placement rack, gravity and the inclined surface work together to automatically guide the fish head to slide to the center area of ​​the gap, solving the tediousness of manual adjustment and positioning. At the same time, the design of the lower side of the inclined surface closely adhering to the gap ensures that the cutting part of the fish head is precisely below the downward trajectory of the knife, avoiding increased chopping resistance or skewed cuts due to positional deviation.

[0009] Furthermore, a blade is provided in the gap of the support plate, and a quick-release mechanism for replacing the blade is provided on the back of the support plate.

[0010] By adopting the above technical solution, the design of the blade embedded in the gap of the support plate makes the movement trajectory of the blade constrained by the rigid channel, completely eliminating the directional deviation of manual chopping, and ensuring that the path of each cut is completely aligned with the center line of the fish head. At the same time, the quick-release mechanism on the back adopts modular assembly logic, which can realize the quick replacement or sharpening maintenance of the blade by unlocking at a single point, solving the problem of the overall scrapping of traditional one-piece blades due to wear.

[0011] Furthermore, the quick-release mechanism is threadedly connected to the through hole provided in the support plate. The quick-release mechanism includes a screw head, a screw rod is fixedly connected to one side of the screw head, and a nut is provided at the tail of the screw rod. The nut is located outside the through hole provided in the support plate.

[0012] By adopting the above technical solution, the through-hole threaded connection structure enables the quick-release mechanism and the support plate to form a self-locking rigid interface. The double-end locking mechanism of the screw head and nut provides ultra-high vibration resistance and stability, ensuring that the knife has no risk of loosening when subjected to high-intensity chopping impact. At the same time, the design of the screw through the through hole simplifies the assembly process: the operator only needs to tighten the nut to complete the axial pressing and fixing of the knife, and the screw can be removed by reversing the operation during disassembly.

[0013] Furthermore, the blade tip is provided with a circular hole, and the screw is provided with a rotating shaft of the same width as the circular hole, the rotating shaft being rotatably connected to the screw.

[0014] By adopting the above technical solution, the circular hole at the tip of the blade and the rotating shaft on the screw form a rotary pair mechanism, which causes the blade to swing around the rotating shaft in a lever-like manner during the chopping process. This design converts the operator's vertical downward pressure into the rotational cutting force of the blade edge, significantly reducing the hand strength required to split hard fish bones. At the same time, the clearance fit between the rotating shaft and the circular hole allows the blade to automatically reset at the end of the cut.

[0015] Furthermore, anti-slip cotton of the same size as the base plate is provided below the base plate.

[0016] By adopting the above technical solution, the anti-slip cotton under the base plate fully covers the bottom surface of the base, which increases the friction coefficient to resist the horizontal impact force during the cutting operation, and prevents positioning failure or safety accidents caused by tool displacement. At the same time, the flexible contact between the anti-slip cotton and the worktable can effectively absorb the instantaneous vibration generated when the knife cuts the fish bone, and protect the connection structure between the support plate and the guide cone from metal fatigue damage.

[0017] Furthermore, the base plate is bolted to any working plate.

[0018] By adopting the above technical solution, the bolt-mounted structure of the base plate allows the knife to be detachably fixed to any standard workbench, breaking through the positional limitations of traditional benchtop tools and meeting the application needs of various scenarios such as mobile stalls and confined kitchen spaces. In summary,

[0019] The present invention has the following main advantages:

[0020] 1. This utility model directly replaces the traditional manual grasping action by physically fixing the fish head with a pointed hook, forming a rigid constraint to avoid the risk of the fish head slipping off during operation. At the same time, the 'C'-shaped placement frame and its inclined bottom plate automatically guide the fish body to slide into the center of the gap, eliminating the redundancy of manual adjustment and positioning. The movement trajectory of the knife, which is rigidly constrained by the gap of the support plate, forms a spatial interlock with the fixed position of the hook, ensuring zero deviation of the chopping path.

[0021] 2. This utility model converts vertical downward pressure into rotational cutting force through the lever structure formed by the rotating shaft and the blade, reducing the intensity of bone-breaking operations. At the same time, the screw and nut of the quick-release mechanism provide a tool-free maintenance path, shortening the tool replacement time. The anti-slip cotton on the base plate effectively suppresses the risk of workbench displacement. The bolt installation interface is adaptable to deployment needs in multiple scenarios, making professional-grade fish head splitting operations both industrial safety and civilian flexibility.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] In this embodiment:

[0029] A type of black carp head segmentation and positioning tool, such as Figure 1-4 As shown, the device includes a knife 1, a base plate 2 on the knife 1, a support plate 3 fixedly connected above the base plate 2, a guide cone 4 fixedly connected to one side of the support plate 3, and a placement frame 5 fixedly connected to the support plate 3 on the lower outer periphery of the guide cone 4. The placement frame 5 is C-shaped, and a gap 10 is formed between the placement frame 5, the guide cone 4 and the support plate 3. The placement frame 5 includes a placement frame base plate 501, and two sets of hooks 9 fixed to the support plate 3 are provided above the guide cone 4. One side of the hook 9 is pointed, and the hook 9 is used for positioning and fixing the fish head.

[0030] By adopting the above technical solution, the conical structure of the guide cone 4 enables the top of the fish head to be quickly centered and positioned, greatly improving the initial placement efficiency; the two sets of pointed hooks 9 penetrate the hard bone tissue of the fish head to form an axial lock, completely eliminating the risk of dislocation of the fish head caused by chopping vibration in traditional methods. At the same time, the 'C'-shaped placement rack 5 provides a U-shaped support surface for the fish body, and the gap 10 formed by the support plate 3 and the guide cone 4 together forms a three-dimensional limiting space, ensuring that the fish head is always in the center of the cutting path; this structure allows the operator's hands to be completely removed from the fish body, fundamentally eliminating the possibility of accidental injury to the hands by the knife. The base plate 2, as the overall support base, ensures the rigid connection of each component, so that the guiding, fixing and cutting functions form a three-in-one synergistic mechanism, significantly improving processing safety and positioning accuracy.

[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The inner side of the base plate 501 of the placement rack is sloping, and the lower side of the base plate 501 is close to the gap 10.

[0032] By adopting the above technical solution, the inner inclined surface design of the base plate 501 of the placement rack forms a sliding rail structure that slopes from the outside to the inside. When the fish body is placed on the placement rack 5, gravity and the inclined surface work together to automatically guide the fish head to slide to the central area of ​​the gap 10, solving the tediousness of manual adjustment and positioning. At the same time, the design of the lower side of the inclined surface closely adhering to the gap 10 ensures that the cutting part of the fish head is precisely located directly below the downward trajectory of the blade 6, avoiding increased chopping resistance or skewed cuts due to positional deviation. This structure is particularly suitable for the horizontal positioning requirements of fish heads of different sizes. The optimized friction of the inclined surface on the slippery fish body further prevents lateral displacement of the fish body during operation, ensuring that the consistency of the cutting position reaches industrial-grade standards each time.

[0033] See Figure 1 , Figure 2 , Figure 3 , Figure 4 A blade 6 is provided in the gap of the support plate 3, and a quick-release mechanism 8 for replacing the blade 6 is provided on the back of the support plate 3.

[0034] By adopting the above technical solution, the design of the blade 6 embedded in the gap 10 of the support plate 3 constrains the movement trajectory of the blade by a rigid channel, completely eliminating the directional deviation of manual chopping and ensuring that the path of each cut is completely aligned with the center line of the fish head. At the same time, the quick-release mechanism 8 on the back adopts modular assembly logic, which can realize the quick replacement or sharpening maintenance of the blade 6 by unlocking at a single point, solving the problem of overall scrapping caused by wear of traditional one-piece blades. This design greatly extends the tool life and reduces the cost of use, especially meeting the stringent requirements for tool maintenance efficiency in high-frequency operation scenarios in the food processing industry.

[0035] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The quick-release mechanism 8 is threadedly connected to the through hole provided in the support plate 3. The quick-release mechanism 8 includes a screw head 81, a screw 82 is fixedly connected to one side of the screw head 81, and a nut 83 is provided at the tail of the screw 82. The nut 83 is located outside the through hole provided in the support plate 3.

[0036] By adopting the above technical solution, the through-hole threaded connection structure enables the quick-release mechanism 8 and the support plate 3 to form a self-locking rigid interface. The double-end locking mechanism of the screw head 81 and the nut 83 provides ultra-high vibration resistance and stability, ensuring that the knife 6 has no risk of loosening when subjected to high-intensity chopping impact. At the same time, the through-hole design of the screw 82 simplifies the assembly process: the operator only needs to tighten the nut 83 to complete the axial pressing and fixing of the knife 6, and the screw 82 can be pulled out by reversing the operation during disassembly, without the need for special tools. This structure replaces the traditional welding or riveting process with the reliability of mechanical threads, achieving a balance between industrial-grade strength and civilian-grade ease of operation.

[0037] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The blade 6 has a round hole 62 at its tip, and the screw 82 has a rotating shaft 61 with the same width as the round hole 62. The rotating shaft 61 is rotatably connected to the screw 82.

[0038] By adopting the above technical solution, the circular hole 62 at the tip of the knife 6 and the rotating shaft 61 on the screw 82 form a rotary pair mechanism, which causes the knife to swing around the rotating shaft 61 in a lever-like manner during the chopping process. This design converts the vertical downward pressure of the operator into the rotational cutting force of the blade 6, which significantly reduces the hand strength required to split hard fish bones. At the same time, the clearance fit between the rotating shaft 61 and the circular hole 62 allows the knife to automatically reset at the end of the cut, avoiding the risk of the knife getting stuck. The rotation trajectory of the knife is physically constrained by the gap 10, ensuring that the range of motion is precisely matched with the cutting path of the fish head, which not only improves the labor-saving effect but also maintains the flatness of the cut.

[0039] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The bottom of the base plate 2 is provided with anti-slip cotton 7 of the same size as the base plate 2.

[0040] By adopting the above technical solution, the anti-slip cotton 7 under the base plate 2 fully covers the bottom surface of the base, which increases the friction coefficient to resist the horizontal impact force during the cutting operation and prevents positioning failure or safety accidents caused by tool displacement. At the same time, the flexible contact between the anti-slip cotton 7 and the workbench can effectively absorb the instantaneous vibration generated when the knife 6 cuts the fish bone, and protect the connection structure between the support plate 3 and the guide cone 4 from metal fatigue damage. This design takes into account both operational stability and equipment durability, and provides inherent safety protection, especially in the slippery aquatic product processing environment.

[0041] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The base plate 2 is mounted on any working plate by bolts.

[0042] By adopting the above technical solution, the bolt mounting structure of the base plate 2 allows the blade to be detachably fixed to any standard workbench, breaking through the positional limitations of traditional benchtop tools and meeting the application needs of multiple scenarios such as mobile stalls and small kitchen spaces. At the same time, the rigid connection provided by the bolt preload can resist the instantaneous reaction force of hundreds of kilograms under the impact of the blade 6, ensuring that the positioning accuracy of the guide cone 4 and the hook 9 does not decrease due to base displacement during long-term use. This expandable design enables the professional-grade fish head splitting equipment to achieve modular deployment for the first time, greatly improving the flexibility of the aquatic product processing operation system.

[0043] The implementation principle of this embodiment is as follows: The fish head is placed under the guide cone 4, so that the top of the fish head is initially positioned close to the conical surface of the guide cone 4. The pointed hook 9 is inserted into the upper tissue of the fish head to achieve axial fixation and prevent the fish head from dislodging. The fish body naturally falls into the 'C'-shaped placement rack 5. The operator holds the knife handle and presses the knife 6 vertically downward. The knife 6 moves down along the gap 10 of the support plate 3 and achieves a lever-type chopping motion through the rotating shaft 61. The blade of the knife 6 accurately cuts into the center of the fish head. The guide cone 4 and the hook 9 are positioned synchronously. The fish bones are split open by gravity acceleration. After the cutting is completed, the nut 83 of the quick release mechanism 8 is loosened and the screw 82 is pulled out to replace or maintain the knife 6.
