Description

Technical Field

[0001] This utility model relates to the technical field of shrimp vein removal tools, specifically a tool for removing the shrimp vein from crayfish. Background Technology

[0002] Crayfish is a nationally renowned delicacy. To ensure its healthiness, the tail and intestinal tract need to be removed during cleaning. The current method involves manually pulling the crayfish by its tail and then yanking the intestinal tract from its abdomen. The drawback of this method is that manually pulling the tail requires twisting it before pulling the tract out from the back, which relies heavily on manual skill. Improper force can easily break the tract, and some crayfish have firm flesh, making it difficult to pull out a complete intestinal tract. In reality, it's not uncommon for the intestinal tract to remain incompletely removed during crayfish cleaning. Therefore, we propose a crayfish intestinal tract removal tool. Utility Model Content

[0003] The purpose of this invention is to provide a tool for removing the shrimp vein from crayfish, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a crayfish vein removal tool, comprising a handle, a back-opening cutter slidably connected to the bottom of the handle, a detachable encapsulating plate installed at one end of the handle, one end of the back-opening cutter abutting against the other end of the handle, the other end of the back-opening cutter abutting against the encapsulating plate, a connecting rod fixedly connected to the other end of the handle, a pull-string ball fixedly connected to one end of the connecting rod, the pull-string ball having a groove for contacting the crayfish vein, a sealing cutter rotatably connected to the bottom of the other end of the handle, a limiting plate fixedly installed on the outside of the sealing cutter, and a baffle fixedly installed near the connecting rod on the handle for interfering with the movement of the limiting plate toward the inside of the handle.

[0005] Preferably, anti-slip grooves are provided on both sides of the top of the handle, and the handle is made of plastic.

[0006] Preferably, gaskets are fixedly installed around the bottom of the handle, and each gasket has at least two threaded holes. A limiting piece is detachably connected between two gaskets located on the bottom of the same side of the handle, and the middle part of the limiting piece extends towards the bottom of the handle to provide an elastic retaining part.

[0007] Preferably, a pair of limiting rods are fixedly installed at the bottom center of the handle, and each limiting rod is distributed next to the top side of the back cutter. A blocking area is provided at the bottom of the handle near each limiting rod.

[0008] Preferably, the bottom cut of the sealing cutter and the bottom cut of the back cutter are located on the same horizontal line, and both the sealing cutter and the back cutter are made of stainless steel.

[0009] Preferably, the pad is 10 mm thick, and a cleaning zone for cleaning is formed between the limiting plate and the handle.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention involves manually holding the handle to vertically cut the back of the lobster with a back-opening cutter, thus opening the lobster's back and fully exposing the intestinal tract, reducing the difficulty of removing it. Finally, after the entire lobster has been opened, the manual person holds the handle again to make a light cut at the tail, making the intestinal tract visible. This allows the manual person to hold the handle, align the pull ball with the intestinal tract, and pull along the lobster's body axis to remove the entire intestinal tract, avoiding the possibility of breakage. This also simplifies and speeds up the process of removing the intestinal tract. Attached Figure Description

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4This utility model provides a technical solution: a crayfish vein removal tool, including a handle 1, a back-opening cutter 4 slidably connected to the bottom of the handle 1, a detachable encapsulating plate 5 installed at one end of the handle 1, one end of the back-opening cutter 4 abutting against the other end of the handle 1, the other end of the back-opening cutter 4 abutting against the encapsulating plate 5, a connecting rod 6 fixedly connected to the other end of the handle 1, a pull ball 7 fixedly connected to one end of the connecting rod 6, the pull ball 7 having a groove for contacting the crayfish vein, and the bottom of the other end of the handle 1 being rotatably connected... A sealing and cutting blade 12 is attached, and a limiting plate 14 is fixedly installed on the outside of the sealing and cutting blade 12. A baffle 13 is fixedly installed on the handle 1 near the connecting rod 6 to allow the limiting plate 14 to move inwards towards the handle 1. First, the lobster is picked up individually by hand. Then, the handle 1 is held with one hand, and the lobster is held with the other hand. The blade of the sealing and cutting blade 12 is aligned with the connection between the lobster's head and body. Next, the sealing and cutting blade 12 is used to cut the lobster horizontally, separating the lobster's intestinal tract from its head. During the cutting of the lobster, as shown in the attached... Figure 4 As shown, the manual can position the pull ball 7 towards the lobster's body, which will cause the handle 1 to be tilted forward. This allows the limiting plate 14 to contact the baffle 13 after being subjected to the force of the sealing cutter 12, making the cutting force of the sealing cutter 12 more stable and improving the effect of the sealing cutter 12 in quickly cutting the lobster. Then, the manual holds the handle 1 and vertically cuts the back of the lobster with the back-opening cutter 4 to open the lobster's back, allowing the shrimp vein to be fully exposed after the back is opened, reducing the difficulty of removing the shrimp vein. Finally, after the entire lobster has been opened, the manual holds the handle 1 and makes a light cut on the tail of the lobster to make the shrimp vein visible. This makes it easier for the manual to hold the handle 1, align the pull ball 7 with the shrimp vein, and pull along the lobster's body axis to pull out the entire shrimp vein, avoiding the possibility of the shrimp vein breaking. This also makes the process of removing the shrimp vein simple and quick. The sealing cutter 12 will flip outward when the handle 1 is tilted, which will not affect the cutting depth of the back cutter 4.

[0015] Furthermore, anti-slip grooves 2 are provided on both sides of the top of the handle 1, and the handle 1 is made of plastic. The anti-slip grooves 2 prevent slipping when pressing manually, and the material of the handle 1 reduces production costs.

[0016] Furthermore, gaskets 11 are fixedly installed around the bottom of the handle 1. Each gasket 11 has at least two threaded holes. A limiting piece 3 is detachably connected between two gaskets 11 located on the bottom of the same side of the handle 1. The limiting piece 3 has a retaining part 301 that extends from the middle of the limiting piece 3 towards the bottom of the handle 1, giving it an elastic function. The two threaded holes facilitate the replacement of the limiting piece 3, allowing it to accommodate lobsters of different sizes. When the back-cutting knife 4 cuts, the limiting piece 3 always keeps the back-cutting knife 4 in a slightly centered position, preventing it from cutting in other directions and causing difficulty in cleaning the shrimp vein later.

[0017] Furthermore, a pair of limiting rods 9 are fixedly installed at the bottom center of the handle 1. Each limiting rod 9 is distributed next to the top side of the back-opening cutter 4. A blocking area 8 is provided at the bottom of the handle 1 near each limiting rod 9. When the lobster is opened, the back of the lobster is in two halves. The limiting rods 9 and the blocking area 8 can limit the opening of the back of the lobster when the back-opening cutter 4 cuts, preventing the back of the lobster from resetting after being opened, which helps to reduce the difficulty of cleaning the shrimp vein.

[0018] Furthermore, the bottom cut of the sealing cutter 12 and the bottom cut of the back cutter 4 are located on the same horizontal line, and both the sealing cutter 12 and the back cutter 4 are made of stainless steel, ensuring that the sealing cutter 12 and the back cutter 4 have the same force points, making it convenient and labor-saving for manual use of the tools.

[0019] Furthermore, the gasket 11 is 10mm thick, and a cleaning area 10 for cleaning is formed between the limiting plate 3 and the handle 1. The cleaning area 10 can be quickly cleaned with clean water to remove dirt remaining on the limiting plate 3, preventing the limiting plate 3 from becoming clogged and difficult to use.
