Description

Technical Field

[0001] This utility model relates to the field of scissors technology, and in particular to a special scissors for opening crayfish. Background Technology

[0002] Crayfish (scientific name: *Procambarus clarkii*) are aquatic animals belonging to the class Crustacea, order Decapoda, and family Procambaridae. They resemble shrimp in shape but have a hard exoskeleton. Crayfish consist of 20 segments, including the cephalothorax and abdomen, and have a hard exoskeleton. Their tail is a tail fan, typically comprising a median fan and lateral fans located on either side of the median fan. They belong to the phylum Arthropoda, have no invertebrate, and their intestine is a thin vena cava, with the anus located on the median fan at the end of the vena cava. When preparing crayfish for consumption, the gills and vena cava need to be removed because they contain mud, sand, and bacteria. Typically, the gills, vena cava, and head need to be removed. The head of the crayfish is usually removed using ordinary scissors.

[0003] A search revealed that Chinese utility model patent CN202120912202.9 discloses a shrimp shear, comprising an upper shear blade and a lower shear blade. The lower edge of the upper shear mounting part is provided with a first upper arc groove, an upper pressing block, and a second upper arc groove, with the upper pressing block located between the first and second upper arc grooves. The upper edge of the lower shear mounting part is provided with a lower arc groove, the position and width of which match the overall position and width of the first upper arc groove, the upper pressing block, and the second arc groove. The lower arc groove and the upper pressing block move in a staggered manner with a gap between them. During the gradual closing of the upper and lower shear blades, the first and second upper arc grooves and the lower arc groove gradually clamp the side fan of the shrimp tail on both sides. At the same time, the upper pressing block gradually presses down on the middle fan of the shrimp tail and pulls it off downwards. Using this patented shrimp shear is simple to operate, improves efficiency, and ensures the pre-processing effect of crayfish, solving the problem of not having a usable tool for removing the shrimp vein.

[0004] For example, Chinese utility model patent application number CN202321928588.8 discloses a novel crayfish peeling device, including an upper blade component, a lower blade component, and rivets; the rivets pass through through holes in the upper and lower blade components and are riveted together. The upper blade component includes a first handle and a first blade; the middle surface of the first blade has a through hole; one end of the first blade is fixedly connected to the first handle. This utility model device resembles scissors in shape, has a simple design, is easy to operate, has a good meat-removing effect, and the user will not be scratched by the hard crayfish claws; it does not require electricity, has multiple functions, can be easily used outdoors, and has strong applicability.

[0005] While the existing scissors can meet basic usage needs, their blades are sharp and straight, making it impossible to remove the internal organs from the shrimp head. Furthermore, the straight blades can easily slip when cutting shrimp heads due to excessive force. Therefore, it is necessary to further improve the existing shrimp scissors. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a special scissor for opening crayfish, which addresses the above-mentioned defects of the prior art.

The inner side of the second blade is provided with a second cutting edge, and the second cutting edge has a second arc groove corresponding to the first arc groove.

[0009] Preferably, the end of the buckle is upturned, and the longitudinal section of the buckle is arc-shaped.

[0010] Preferably, the longitudinal section of both the first and second arc-shaped grooves is arc-shaped.

[0011] Preferably, the first blade is provided with a clamping part, and a clamping groove adapted to the second blade is provided below the clamping part.

[0012] Preferably, the first handle has a first hand grip through hole, and the second handle has a second hand grip through hole that is symmetrical to the first hand grip through hole.

[0013] Preferably, both the inner side of the first handle and the inner side of the second handle are provided with clamping saws, and the clamping saws are provided with a plurality of sawtooth grooves.

[0014] By adopting the above technical solution, the crayfish-opening scissors provided by this utility model have the following beneficial effects: the first handle and the second handle of the crayfish-opening scissors are respectively connected to the first blade and the second blade. The first blade is rotatably connected to the second blade through a pin. The end of the first blade is provided with a raised buckle. The inner side of the first blade is provided with a first cutting edge, and the first cutting edge has a first arc groove. The inner side of the second blade is provided with a second cutting edge, and the second cutting edge has a second arc groove corresponding to the first arc groove. By setting the buckle on the first blade, the crayfish head can be picked out. When using it, the internal organs inside the crayfish head can be picked out by the buckle. When cutting the crayfish head, the crayfish head can be clamped by the first arc groove and the second arc groove, which is not easy to slip or deform, making it more convenient to use. It has the function of opening the crayfish back, and its functions are diversified, which can meet the needs of users. Attached Figure Description
