TECHNICAL FIELD
[0001] The utility model relates to kitchen utensil technical field, especially special cutting scissors for channel catfish. BACKGROUND
[0002] The cutting method of scaleless fish such as channel catfish and catfish is different from other fish in Chinese cuisine, other fish is directly cut from the fish belly, the internal organs of the fish are taken out, and the fish body is cut into two pieces along the spine. The vertical section of channel catfish and other fish is triangular, and channel catfish has only one main spine, and the fish belly has no spine. If the fish belly of channel catfish is directly cut open, the integrity of the fish meat of channel catfish will be damaged, and since the swim bladder has very high medicinal value, if the fish belly of channel catfish is directly cut open, the swim bladder in the body of channel catfish may be cut. Therefore, when processing channel catfish, the fish belly needs to be cut separately (equivalent to cutting the bottom of the above-mentioned triangular shape), and then the fish body is cut into two pieces along the spine, so that two fish bodies and one fish belly are obtained. In the actual operation process, the fish bones on both sides of the gill can be cut off with a kitchen knife, and then the fish belly is separated respectively, which is troublesome and has a certain degree of difficulty.

[0037] In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as there is no conflict between them.
[0038] Embodiment 1:
[0039] The utility model discloses an embodiment 1 provides a special cutting scissors of flathead catfish, as shown in Figure 1 Two outer arms 1 and two inner arms 2, two inner arms 2 are fixedly connected, two inner arms 2 are X-shaped, two outer arms 1 are respectively arranged on the outer side of two inner arms 2, outer arm 1 is provided with first handle 10, outer arm 1 and first handle 10 are integrally formed, inner arm 2 is provided with second handle 23, inner arm 2 and second handle 23 are integrally formed, outer arm 1 rotates with fixed shaft 11 as the center, two inner arms 2 are relatively fixed, inner arm 2 rotates with fixed shaft 11 as the center, the outer side of inner arm 2 is provided with first blade 20, the inner side of outer arm 1 is provided with second blade 12, first blade 20 and second blade 12 are used to cut fishbone. After the fishbone is clamped off, first blade 20 and second blade 12 are used to cut the fish belly.
[0040] Two inner arms 2 are fixedly connected, specifically including, two inner arms 2 can have two setting forms, the first setting form is as shown in Figure 2As shown, two inner cutter arms 2 can be independently arranged, and then fixedly connected by welding or gluing; the second arrangement is shown in Figure 3 As shown, two inner cutter arms 2 can be integrally formed, and the intersection thereof is rotatably connected with the fixed shaft 11.
[0041] As shown in Figure 4 and Figure 5 , it is a side view of the scissors, Figure 4 corresponding Figure 2 , it is a side view of the two independently arranged inner cutter arms 2 shown in Figure 5 corresponding Figure 3 , it is a side view of the two integrally formed inner cutter arms 2 of the outer cutter arm 1 shown in
[0042] In actual application scenarios, considering the comfort of the user when using the scissors, the outer part of the first handle 10 is covered with silicone (not shown in the figure); secondly, referring to Figure 1 As shown, the first handle 10 is provided with a first recess 100, and the second handle 23 is provided with a second recess 230, the second recess 230 is arranged on the outer side of the second handle 23, and the first recess 100 and the second recess 230 facilitate gripping.
[0043] In actual operation, if the forces of the two pairs of outer cutter arms 1 and inner cutter arms 2 are equal, the fish bones on both sides of the gill can be cut at the same time, but if the forces on both sides are not balanced, one side of the fish bone is cut, and the other side of the fish bone is not cut. At this time, since the two inner cutter arms 2 are fixedly connected, as shown in Figure 6 As shown in the figure, if the upper fish bone is cut first, the lower fish bone has not been cut, and the lower first handle 10 is continuously pinched until the first handle 10 coincides with the second handle 23, and the first handle 10 and the second handle 23 are continuously pinched. The lower inner cutter arm 2 is pushed by the second handle 23, and a greater shearing force is applied to the uncut fish bone by the lower outer cutter arm 1, so as to cut the lower fish bone.
[0044] Compared with the existing method of cutting the channel catfish by using a kitchen knife, in the embodiment of the utility model, the double-scissors structure is formed by the two outer knife arms 1 and the two inner knife arms 2, when cutting the fishbone, the fish head is chopped off by using the kitchen knife, the two inner knife arms 2 are inserted into the fish body to the fishbone below the gill, the two outer knife arms 1 are pinched, the fishbone is clamped in the middle by each outer knife arm 1 and inner knife arm 2, the fishbone is clamped off by the shearing force, the scissors does not need to be taken out, the scissors is slid to the fish tail along the clamped-off part of the fishbone, the fish abdomen can be cut as a whole, and the swim bladder will not be cut, compared with the kitchen knife, the fish abdomen is cut more simply and quickly by using the scissors provided in the embodiment of the utility model, especially in the scene of processing a large number of channel catfish, such as processing factory or hotel kitchen, the fish head of all channel catfish can be chopped off first, then the fish abdomen of the channel catfish is separated, and the processing is convenient for assembly line.
[0045] In order to facilitate the fishbone below the gill to be cut off, continuing to refer to Figure 1 As shown in the figure, the first blade 20 is in the form of a shearing protrusion, the shearing protrusion is triangular, or the shearing protrusion is rectangular. That is, the shearing protrusion is gradually thinned from inside to outside to form the first blade 20. In the preferred scheme, when the shearing protrusion is triangular, a first bevel 200 is arranged at the blade head part of the shearing protrusion, and the first bevel 200 is inclined from the blade head part of the shearing protrusion to the tail part of the inner knife arm 2. Since the inner knife arm 2 needs to be inserted into the fish body during use, the inner knife arm 2 may be hooked by the fish tissue in the fish body during the insertion process. The blade head part of the shearing protrusion is provided with the first bevel 200, and the first bevel 200 is also provided with a blade, which facilitates the insertion of the inner knife arm 2 into the fish body and avoids being hooked by the fish tissue.
[0046] After the fishbone is cut off, the inner knife arm 2 is continuously inserted into the channel catfish body for cutting the fish abdomen. Since there are internal organs in the channel catfish body, in order to avoid the inner knife arm 2 being entangled by the internal organs during the continuous movement to the fish tail, the inner side of the inner knife arm 2 is also provided with a third blade 22, so that the scissors is not stuck by the internal organs in the channel catfish body when advancing to the fish tail direction. At the same time, in order to further ensure the smoothness of the advancement of the scissors, the blade head part of the third blade 22 is provided with a second bevel 220, and the second bevel 220 is inclined from the blade head part of the inner knife arm 2 to the tail part of the inner knife arm 2. The second bevel 220 is also provided with a blade.
[0047] During the process of continuously inserting the inner knife arm 2 into the channel catfish body for cutting the fish abdomen, the included angle between the outer knife arm 1 and the inner knife arm 2 shears the fish abdomen. Since the swim bladder is located below the channel catfish spine, the swim bladder will not be cut during the shearing process. After the fish abdomen is cut off by continuously advancing the scissors forward, the internal organs are taken out, and then the fish body pieces on both sides of the channel catfish spine are cut off by using the kitchen knife, a complete fish abdomen and two fish bodies are obtained.
[0048] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
