The utility model provides a fish scissors 100 for cut culinary art and eat material etc.. Of course, the scissors 100 may also be used to cut materials other than food materials, such as paper and the like.

The scissors 100 include a first cutting arm 10 and a second cutting arm 20, and the first cutting arm 10 is rotatably connected to the second cutting arm 20. The first scissor arm 10 cooperates with the second scissor arm 20 and performs a cutting function.

The first shear arm 10 includes a first blade 11, and the second shear arm 20 includes a second blade 21, where the first blade 11 is opposite to the second blade 21. The first blade 11 and the second blade 21 can be opened or closed relatively through a rotation point. Therefore, the scissors 100 have an open state in which the first blade 11 and the second blade 21 are opened to each other; the scissors 100 have a closed state in which the first blade 11 and the second blade 21 are closed to each other.

In one embodiment, the first scissor arm 10 further includes a first handle portion 12; the first handle 12 is fixedly connected to the first blade 11. The second scissor arm 20 further includes a second handle portion 22; the second handle portion 22 is fixedly connected to the second blade portion 21. The first and second handle portions 12, 22 are each adapted to be gripped by the hands of an operator. The first blade 11 and the first handle 12 are respectively located at two sides of the rotation point of the first shear arm 10 and the second shear arm 20. The relative folding of the first handle 12 and the second handle 22 can drive the relative folding of the first blade 11 and the second blade 21 and achieve the purpose of cutting, that is, the first blade 11 and the second blade 21 can be switched back and forth between the open state and the closed state.

It is understood that in other embodiments, the first handle portion 12 and the second handle portion 22 are not essential components, and the operator can directly press or pull the side of the first blade 11 and the second blade 21 away from each other to change the open state or the closed state of the first blade 11 and the second blade 21.

In one embodiment, the first shear arm 10 is substantially elongated, and the first blade 11 is disposed at one side of the first shear arm 10 in the length direction and located at the front section of the first shear arm 10; the first handle portion 12 is located at a mid-rear section of the first scissor arm 10. The arrangement is convenient for the first handle part 12 to control the rotation angle and the position of the first blade part 11.

It is understood that in other embodiments, the first shear arm 10 may be provided with other shapes, such as a column shape, as long as the first shear arm can be rotatably connected with the second shear arm 20 and can be relatively folded for shearing; the positions of the first blade 11 and the first handle 12 can be set according to actual requirements, as long as the first handle 12 can drive the first blade 11 to rotate.

The first blade 11 is usually made of metal and is embedded in the end of the first handle 12. It is understood that, in other embodiments, if the first blade portion 11 and the first handle portion 12 can be made of the same material, the first blade portion 11 and the first handle portion 12 can also be made of an integral structure, as long as the function of cutting can be achieved by the engagement between the first blade portion 11 and the second cutting arm 20.

In one embodiment, the first handle portion 12 is provided with an anti-slip sleeve (not numbered) at the periphery thereof, so that the operator can increase the friction between the first handle portion 12 and the hand as much as possible when using the handle, and can rotate the first blade portion 11 by pressing the first handle portion 12. It will be appreciated that in other embodiments, the first handle portion 12 may be provided with anti-slip protrusions on its outer periphery to achieve the anti-slip purpose described above.

Similarly, the second handle portion 22 is provided at its outer periphery with an anti-slip cover (not numbered) so that the operator can increase the friction between the second handle portion 22 and the hand as much as possible during use, and can rotate the second blade portion 21 by pressing the second handle portion 22.

In one embodiment, the connection between the first handle 12 and the first blade 11 is provided with a bend (not numbered) to allow the space between the first handle 12 and the second handle 22 to be adapted to the hand grip.

The structure and function of the second scissor arm 20 are similar to those of the first scissor arm 10, and are not described in detail herein.

The scissors 100 further include a rotating member 30, wherein the rotating member 30 is disposed at a position where the first cutting arm 10 and the second cutting arm 20 intersect with each other and overlap each other, and the first cutting arm 10 and the second cutting arm 20 can rotate relative to the rotating member 30. The rotor 30 is provided at a bent portion between the first blade 11 and the first handle 12, and is also provided at a bent portion between the second blade 21 and the second handle 22. The first scissor arm 10 and the second scissor arm 20 are rotatably and fixedly connected through the rotating part 30, that is, the distance between the first scissor arm 10 and the second scissor arm 20 is within a proper range, so that the first scissor arm 10 and the second scissor arm 20 can rotate relatively, and the distance between the first scissor arm 10 and the second scissor arm 20 cannot be too large and scattered, so that the purpose of shearing cannot be achieved.
