[0020] The components shown in the figure are: a blade 1 , a blade head 11 , a blade tail 12 , an elastic spring 2 , a semicircular structure 21 , an inverted triangle structure 22 , and a handle 3 . DETAILED DESCRIPTION

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 and Figure 5 As shown, an embodiment of the present application discloses a shrimp peeling knife, comprising a blade 1, one end of the blade 1 being a blade head 11, and the other end of the blade 1 being a blade tail 12, an elastic reed 2 being obliquely arranged on one side of the blade head 11 along the blade 1, one end of the elastic reed 2 being connected to the blade 1, and the other end of the elastic reed 2 being not connected to the blade 1, and an acute angle between the elastic reed 2 and the blade 1 in the direction of the blade tail 12, so that when the blade 1 is inserted from the shrimp head, the elastic reed 2 can be inserted into the shrimp meat, and the shrimp meat can be pulled out when the blade 1 is pulled backward.

[0023] Specifically, when in use, the shrimp head of the crayfish is first peeled off, and then the blade head 11 of the blade 1 is inserted between the shrimp meat and the shrimp shell at the shrimp head end. Since the elastic spring 2 has a certain elasticity, the blade 1 is pressed toward the shrimp meat at this time, and the elastic spring 2 is in a pressed state close to the blade 1. Then the blade 1 moves toward the shell body, so that the elastic spring 2 pops out, and the end of the elastic spring 2 is inserted into the shrimp meat. Then, the blade 1 is pulled outward, so that under the action of the elastic spring 2, the shrimp meat can be pulled out together.

[0024] The shrimp peeling knife has a simple structure and only requires the blade 1 and its elastic reed 2 to directly hook out the shrimp meat during the shrimp peeling process, thereby making the shrimp peeling process convenient, simple and quick.

[0025] In this embodiment, a plurality of elastic springs 2 are provided, and the plurality of elastic springs 2 are sequentially arranged along one side of the blade 1 .

[0026] Specifically, the elastic reed 2 can be set according to actual needs, and can be 1, 2, 3, etc., and setting a plurality of elastic reeds 2 can ensure that the elastic reed 2 can be inserted into the shrimp meat when it rebounds, and can also reduce the possibility of the elastic reed 2 being unhooked from the shrimp meat when the blade 1 is pulled outward, thereby ensuring the success rate of peeling shrimp.

[0027] In this embodiment, the elastic spring piece 2 is a semicircular structure 21 or an inverted triangle structure 22 .

[0028] Specifically, the specific shape of the elastic spring 2 can be a variety of shapes and structures, such as square, arc, and strip. In the present embodiment, it is mainly a semicircular structure 21 or an inverted triangle structure 22. The inverted triangle structure 22 is preferred because the end of the inverted triangle is a pointed end. On the one hand, this shape can ensure that when the elastic spring 2 rebounds, the pointed end of the inverted triangle can be inserted into the shrimp meat to pull out the shrimp meat. On the other hand, this structure makes the connection area between the elastic spring 2 and the blade 1 large, so it has good resilience and is not easy to break.

[0029] In this embodiment, the blade 1 is an arc-shaped structure, and the elastic spring 2 is located on the outer side or the inner side of the arc-shaped structure. The arc-shaped structure is close to the curvature of the crayfish tail.

[0030] It should be explained that the blade side in the present application may be a vertical structure, specifically as follows Figure 5 As shown, it can also be an arc structure, as shown in Figure 1 and Figure 4 As shown, an arc-shaped structure is preferred.

[0031] When the elastic spring 2 is located inside the arc of the blade of the arc structure, the schematic diagram is as follows: Figure 1 As shown, when it is in use, the blade is inserted between the shrimp shell and the shrimp back, and the elastic reed 2 is located close to the shrimp meat.

[0032] When the elastic spring 2 is located outside the arc of the blade of the arc structure, the schematic diagram is as follows: Figure 4 As shown, when it is in use, the blade is inserted between the shrimp shell and the shrimp abdomen, and the elastic reed 2 is located near the shrimp meat.

[0033] In this structure, by setting the blade 1 into an arc structure, the blade 1 can conform to the arc rule of the shrimp, so that the blade 1 can be easily inserted from the shrimp head end into the middle of the shrimp meat and the shrimp shell, thereby facilitating the subsequent shrimp meat hooking process.

[0034] In this embodiment, the width of the head portion 11 of the blade 1 is smaller than the width of the tail portion 12 of the blade 1 .

[0035] Specifically, in the present structure, the width of the blade head 11 is set to be smaller than the width of the blade tail 12. Since the width of the blade head 11 is narrow, the blade head 11 can be conveniently inserted into the crayfish during the shrimp peeling operation, so that even small shrimp meat can be smoothly inserted into the blade head.

[0036] In this embodiment, the knife tail 12 is provided with a handle 3, and the blade 1 and the handle can be connected by bolts, pins or other fixed connection methods. The material of the handle 3 can also be various materials such as wood, bamboo, etc., which can be selected according to needs.

[0037] In this structure, the handle 3 is provided, so that the blade 1 can be conveniently inserted into the crayfish with force. Meanwhile, the handle 3 can also prevent the blade 1 from cutting fingers due to excessive force.

[0038] In this embodiment, the blade 1 is a stainless steel sheet, and the thickness of the stainless steel sheet is 0.5 mm-1 mm, specifically 0.5 mm, 0.8 mm, 1 mm, etc.

[0039] Specifically, the blade 1 of the present structure is made of stainless steel, and the stainless steel material has moderate hardness and softness, which can ensure that the blade 1 can be inserted into the crayfish without damaging the shrimp meat due to the blade 1 being too hard. At the same time, the thickness of the stainless steel sheet in the present structure is set to 0.5mm-1mm, which can ensure that the hardness of the blade 1 is within a suitable range. At the same time, this thickness also makes it convenient to insert the blade 1 between the shrimp meat and the shrimp shell, thereby facilitating the shrimp peeling process.

[0040] In this embodiment, the elastic spring 2 and the blade 1 are integrally formed by punching.

[0041] Specifically, when processing the elastic reed 2, it can be punched out or the elastic reed 2 and the blade 1 can be welded into shape, but punching is preferred. This method can achieve one-piece forming of the elastic reed 2 and the blade 1, thereby eliminating the need for additional elastic reed 2 material. At the same time, the one-piece forming method can also ensure its good elasticity.

[0042] In this embodiment, the angle between the elastic spring 2 and the blade 1 in the direction of the blade tail 12 is 15-45°.

[0043] Specifically, the above-mentioned angle can be 15°, 30°, 45°, etc. The setting of the above-mentioned angle range can ensure the elasticity of the elastic reed 2 during use, and also enable the elastic reed 2 to be smoothly inserted into the shrimp meat after the elastic reed 2 is reset, thereby facilitating the hooking of the shrimp meat.

[0044] In this embodiment, the length of the elastic spring 2 is 10mm~15mm, specifically 10mm, 13mm, 10mm, etc. The distance between the connecting end of the top elastic spring 2 and the blade 1 and the end of the blade head 11 is 2mm-8mm, specifically 2mm, 4mm, 8mm, etc.

[0045] Specifically, the distance and length are set according to the average size of crayfish. Such distance and length can facilitate the peeling of crayfish without damaging the shrimp meat.

[0046] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
