[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Specific details such as specific system structures and technologies are proposed in order to more thoroughly understand the embodiments of the present invention. The described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. However, it should be clear to those skilled in the art that the present invention can also be implemented in other embodiments without these specific details. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection disclosed by the present invention.

[0027] Example 1

[0028] refer to Figure 1 and Figure 2 This embodiment provides a simple tool for processing fish and shrimp, including a handle 1, a back-opening knife 2 arranged at the end of the handle 1, and a clamping spring piece 3 arranged at the end of the handle 1, wherein the clamping spring piece 3 is arranged on opposite sides of the back-opening knife 2, the clamping spring piece 3 and the back-opening knife 2 are located at the same end of the clamping spring piece 3, and the clamping spring piece 3 and the back-opening knife 2 are arranged in the same direction.

[0029] The handle 1 can be made of common materials such as wood, food-grade stainless steel or food-grade plastic.

[0030] The back-opening knife 2 can be selected as a flat structure, a curved structure with an arc in cross section, or other structures that are conducive to cutting fish and shrimp, and the back-opening knife 2 can be selected as a single-edged blade or a double-edged blade to increase service life.

[0031] There are two clamping spring pieces 3, and the back-opening knife 2 is set between the two clamping spring pieces 3. Preferably, the back-opening knife 2 is located in the middle of the two clamping spring pieces 3, that is, the two clamping spring pieces 3 are symmetrically arranged about the back-opening knife 2.

[0032] The clamping spring piece 3 can be made of the same material as the handle 1, and the clamping spring piece 3 can be selected to be an integrated structure with the handle 1 to improve structural reliability; the clamping spring piece 3 and the handle 1 can also be detachably connected to facilitate replacement.

[0033] When the clamping spring piece 3 is detachably connected to the handle 1, the bottom of the clamping spring piece 3 is tightly connected to the end of the handle 1 to prevent the bottom of the clamping spring piece 3 from shaking; the clamping spring piece 3 and the handle 1 can be connected by plugging, snapping or magnetic attraction, and preferably the connection is detachable by plugging. At this time, a pop-up slot is provided on the handle 1, and the bottom of the clamping spring piece 3 is detachably connected to the handle 1 through the pop-up slot.

[0034] Preferably, the clamping spring 3 is made of a material that can be deformed and reset, such as spring steel or plastic.

[0035] In actual use, the processing of freshwater shrimp is used as an example to illustrate:

[0036] The operator can hold the handle 1 and place the shrimp on the chopping board with the back facing upward and the head facing the handle 1.

[0037] Next, align the tip of the back-opening knife 2 with the middle position below the head of the prawn, and at the same time apply a small force to the two clamping springs 3 so that the two clamping springs 3 can stably clamp the prawn from both sides.

[0038] Then, the handle 1 is used to push the back-opening knife 2 toward the shrimp tail to open the back of the shrimp; the two clamping springs 3 clamp the shrimp to prevent the shrimp from twisting, ensuring that the back-opening knife 2 can keep cutting the middle position of the shrimp during the movement, thereby improving the processing quality of the shrimp.

[0039] After the back is opened, the back opening knife 2 and the clamping spring piece 3 on one side can be used to form tweezers to remove the shrimp thread and pancreas and other waste materials in the shrimp, thereby completing the processing of the shrimp. The operation is simple and efficient, and the processing quality of the shrimp can be improved.

[0040] In order to facilitate the removal of waste from the shrimp, it is preferred that the top of the clamping spring piece 3 extends to the outside of the top of the back-opening knife 2, that is, the length of the clamping spring piece 3 is greater than the length of the back-opening knife 2; for example, the back-opening knife 2 is flush with the bottom of the clamping spring piece 3 and is located at one end of the handle 1. The length of the back-opening knife 2 is 60 mm, and the length of the clamping spring piece 3 is 75 mm, so that tweezers can be formed between the two clamping spring pieces 3 for processing operations, further reducing the difficulty of operation and improving processing efficiency.

[0041] The length of the handle 1 is determined according to the size of the object to be processed. For example, when processing freshwater shrimp, the length of the handle 1 can be selected to be 60mm to 110mm. When processing grass carp, the length of the handle 1, the length of the back-opening knife 2, and the length of the clamping spring piece 3 can all be increased, so that the handle 1 is easy to hold when used, the back-opening knife 2 can cut into a sufficient depth, and the clamping spring piece 3 can clamp stably; when processing freshwater shrimp, the length of the handle 1 can be selected to be 80mm.

[0042] Further explanation, in order to improve the reliability of the clamping spring piece 3 in processing shrimp waste, anti-slip serrations 4 are set at the end of the clamping spring piece 3. The anti-slip serrations 4 are located on the inner side of the clamping spring piece 3 to prevent the clamped object from slipping.

[0043] Further explanation: in order to avoid the clamping spring piece 3 being slippery and inconvenient to apply force when opening the back of the shrimp, it is preferably provided with an anti-slip ridge 5 on the outer side of the bottom of the clamping spring piece 3 to increase the friction and ensure that the clamping spring piece 3 is stably applied with force during use.

[0044] Preferably, the structural area of ​​the location where the force is applied to the clamping spring piece 3 is increased to further increase the contact area and ensure safe and reliable use.

[0045] Example 2

[0046] refer to Figure 3 Unlike Example 1, the simple tool for processing fish and shrimp provided in this embodiment also includes a reset spring 6. At this time, the clamping spring 3 is movably connected to the handle 1 through the reset spring 6, that is, the bottom of the clamping spring 3 can move at the end of the handle 1 under the action of the reset spring 6.

[0047] In actual use, force can be directly applied to the clamping spring piece 3 to clamp fish and shrimp.

[0048] In order to reduce the difficulty of manually applying force to clamp the fish and shrimp, the return spring 6 is preferably a torsion spring.

[0049] At this time, two clamping grooves b are formed on the top of the handle 1 , the notches of the clamping grooves b face away from the back opening knife 2 , and the back opening knife 2 is located between the two clamping grooves b.

[0050] A rotating shaft is provided in the clamping groove b, and the rotating shaft is provided in the clamping groove b along the width direction of the back opening knife 2. A connecting sleeve a is provided at the bottom of the clamping spring piece 3, and the connecting sleeve a is sleeved on the outside of the rotating shaft. A slot is provided in the middle position of the connecting sleeve a, and a torsion spring is sleeved on the outside of the rotating shaft. The two spring arms of the torsion spring extend from the slot to the outside of the connecting sleeve a, one spring arm of the torsion spring contacts the top of the slot, and the other spring arm of the torsion spring contacts the bottom of the clamping groove b, so that the clamping spring piece 3 is close to the back opening knife 2 under the action of the torsion spring.

[0051] In actual use, the two clamping springs 3 and the back-opening knife 2 can be manually separated, and then the fish and shrimp are placed between the two clamping springs 3, and then the torsion spring is used to actively clamp the fish and shrimp.

[0052] At the same time, when discarding fish and shrimp, it is necessary to apply force to separate the two clamping springs 3, and use the torsion spring to make the two clamping springs 3 actively clamp the waste to complete the processing of fish and shrimp. The operation is simple and quick.

[0053] Further explanation, the reset spring 6 can also be selected as a tension spring. At this time, the bottom of the clamping spring piece 3 is connected to the rotating shaft through the connecting sleeve a. The rotating shaft is arranged along the width direction of the back opening knife 2. The tension spring is located above the connecting sleeve a. One end of the tension spring is connected to the bottom of the clamping spring piece 3, and the other end of the tension spring is connected to one side of the clamping groove b. The tension spring is located between the clamping spring piece 3 and the back opening knife 2, so that the clamping spring piece 3 is close to the back opening knife 2 in the default state.

[0054] In actual operation, it is only necessary to manually separate the two clamping springs 3 to clamp fish or shrimp or use them as tweezers.

[0055] Further explanation, the reset spring 6 can also be selected as a compression spring. In this case, a movable groove is opened at the end of the handle, and the movable groove only opens a top port. The bottom of the clamping spring 3 is rotatably connected to the movable groove through a rotating shaft. The compression spring is located between the clamping spring 3 and the side end face of the movable groove. In the initial state, the compression spring pushes the clamping spring 3 close to the back opening knife 2.

[0056] At the same time, the compression spring and tension spring can be interchanged during use. At this time, the clamping spring piece 3 is far away from the back knife 2 in the initial state. When in use, force needs to be applied to make the clamping spring piece 3 close to the back knife 2. The usage method is the same as that of Example 1.
