Influence of rod mouth on fishing rod

There is no uniform standard for the fishing rod mouth, as long as the fishing rod is not cracked and the force transmission is smooth. However, the general requirement of fishing gear industry is that the mouth of fishing rod is not less than 25mm, and other cross sections are not less than 40 mm The mouth of fishing rod is related to the mechanical properties of fishing rod. The mouth is too small, the force transmission between joints is not good, and stress concentration is easy to occur at the mouth, which causes the front end of the rod joint to crack and break. Only when the mouth is moderate can the front section effectively transmit the force to the next section.
