The clamping edges of the first scissor blade and the second scissor blade are provided with arc-shaped cutting edges for cutting the head of a shrimp. The arc-shaped cutting edges are arranged close to the pin shaft.

[0006] The end of the first scissor blade is integrally formed with a sharp blade for inserting into the shell of a shrimp.

[0007] The end of the second scissor blade is integrally formed with a back shell opening knife body for opening the back shell of a shrimp.

[0008] Further preferably, the clamping edge of the scissor handle is fixed with a fruit and vegetable shell clamping device in the middle.

[0009] Further preferably, the clamping edge of the fruit and vegetable shell clamping device is integrally formed with a plurality of tooth tips.

[0010] Further preferably, the end of the back shell opening knife body is integrally formed with a upwardly curved knife tip for scooping out the brain of a shrimp.

[0011] It is further preferred that the width of the second scissor blade is greater than the width of the first scissor blade.

[0012] The utility model has positive effect: the utility model's structure setting is reasonable, it is provided with the arc blade edge for arrow shrimp head, can realize the shearing operation to shrimp head to the first scissor blade's end integral forming has pointed blade, can insert into shrimp shell, thus convenient to the shearing operation of shrimp shell, also can pick out shrimp stomach through pointed blade, has promoted the convenience and effectiveness of operation, and it still sets up shrimp back open shell cutter body, is favorable to the open shell operation to shrimp back, thus has promoted the function of overall structure, satisfies the processing demand of different conditions, convenient and fast to use, and the applicability is strong.
