Problems solved by technology

[0003] The purpose of the present invention is to overcome the mussel dissecting knife in the prior art that cannot accurately penetrate into the mussel shell to cut off the adductor muscle, resulting in difficulty in opening the shell, and the radian of the knife plate cannot fit the radian of the mussel shell, resulting in incomplete scraping and cutting of the mussel meat. Loss, and the defect of slow speed, provide an anatomical mussel knife with a blade that can be stretched along the handle or whose curvature can be adaptive, which can meet the requirements of fast, safe and complete scraping and cutting of mussel meat

Embodiment 1

[0028] Embodiment 1: as figure 1 As shown, a mussel dissecting knife whose blade curvature is self-adaptive to the shell shape includes a blade 1 and a handle 2. The blade 1 can be stretched in the cavity of the handle 2 and fixed at an appropriate The position of the knife plate 1 is composed of a steel plate with appropriate torsional rigidity and can be self-adaptively curled corresponding to the curvature of the inner surface of the mussel shell; the hardness of the knife plate 1 is moderate, and the blade line 5 from the tip 3 to the root 4 is a convex curve , the curvature of the convex curve gradually changes from large to small, and the curvature is zero near the root of the knife plate. The curvature of the convex curve conforms to the law of the involute line. This curve structure is conducive to the better fit of the blade to the inner surface of the shell. The tip of the front end of the knife plate 1 is a small arc 6 structure of R2-R5, and the small arc structure...

Embodiment 2

[0050] Embodiment 2: A cavity is provided in the handle 2, and several locking grooves are provided. A lower adjustment block is movable above the handle. The front end of the lower adjustment block is provided with a protrusion matching the blade fixing hole. A locking block groove is arranged in the block, and a T-shaped locking block is movable in the locking block groove. The lower end of the locking block matches the locking groove, and a movable upper adjusting block is arranged above the lower adjusting block. A push groove is provided, the outside of the push groove is wide and the inside is narrow. The end is in conflict with the inner wall of the upper adjustment block, the bottom of the elastic piece is locked and matched with the top of the locking block, and a reset device is also arranged in the upper adjustment block. All the other structures are with embodiment 1.

Embodiment 3

[0051] Embodiment 3: knife plate 1 is fixedly connected with knife handle 2, and the shape of the blade of knife plate 1 and the back of a knife is each a section of involute, and the base circle diameter of the involute one 8 of the knife edge is greater than the involute two 9 of the back of the knife its base circle diameter. The first involute 8 of the blade is connected with the second 9 of the involute 9 of the back of the knife to form the shape of a horn. In order to adjust the curvature, it can be achieved by adjusting the size of the base circle diameter of the involute or selecting arc segments in different regions of the involute. The rest of the structures are the same as in Embodiment 1, see figure 2 .

Abstract

The invention discloses a shell-shaped mussel dissection tool with the adaptive cutting board curvature. The shell-shaped mussel dissection tool comprises a tool plate and a tool handle. The tool plate is fixedly connected with the tool handle, and the tool plate can stretch and contract in a cavity of the tool handle and is fixed to a proper portion according to the needed stretching length. Thetool plate is composed of a steel plate which has proper torsion rigidity and corresponds to the inner surface of a mussel, wherein the steel plate can be adaptively curled. The tool plate has the proper hardness, and a blade line, from the sharp end part to the root part, of the tool plate is a section of protruding curve, and the curvature of the protruding curve is gradually changed from largeto small from the sharp end of the tool plate to the root part of the tool plate. By means of the mussel dissection tool of which the tool plate can stretch and contract along the tool handle or of which the curvature is adaptive, the requirement for rapidly, safely and completely scraping and cutting mussel flesh can be met.

Description

technical field [0001] The invention relates to the technical field of cutters, in particular to a shellfish processing cutter. Background technique [0002] As a traditional cultured shellfish in my country, mussels are widely distributed in coastal areas of China. Mussels have high nutritional value and are generally recognized for their medicinal value. In terms of ecology, shellfish connect primary producers and advanced consumers at the same time, are an important link in energy flow, and play an important role in coastal ecosystem functions. In addition, mussels have become popular model animals in marine environmental monitoring research due to their long life cycle, sessile growth characteristics, filter feeding, accumulation of toxins in the body, and global distribution. Mussel plumpness is a measure used to measure the degree of mussel soft tissue development. In the process of mussel plumpness determination, an important step is to completely remove the mussel ...
