Background

Fishing is an outdoor sport well enjoyed by the masses in modern life, and generally, when going out for fishing, a fisher often uses a high-strength fishing line, namely PE (polyethylene) line, which has excellent strength and breaking resistance when dealing with big or fierce fishes, but causes troubles when in use; for example, when the PE wire is cut, replaced, tied with a hook and cleaned, the common scissors are continuously cut due to high fracture resistance, but in the prior art, the problem that the common scissors are easy to cut continuously also occurs in a plurality of special scissors aiming at the problem, the common scissors are mainly divided into two types, one type is metal-edge scissors, two scissors edges are manually pulled to be slightly crossed after assembly, and the PE wire is cut off under the action of an interference cutting additional saw. But has the following disadvantages: because the PE wire is usually used in a sea fishing environment and is often contacted with seawater with higher salt content, the metal blade is easy to corrode and rust; in addition, because the shearing mode is interference and intersection, product life is not long, and interference shearing can wear and tear the serration on the tool setting sword, finally leads to unable normal trimming. The other scissors use ceramic material to replace metal cutting edge, and utilize the high hardness and non-rust property of ceramic material to cut off PE wire. But has the disadvantages that: because of the ceramic material is very hard, can not be after the assembly artificially turn two scissors sword into slightly crisscross interference shearing mode, if it is the specific processing for just interfering the shearing size, the big processing cost of the processing degree of difficulty is very high, and it is still big than the metal to interfere the wearing and tearing of shearing to pottery in addition, and its yields can not be guaranteed to current pottery PE scissors.
