CONNECTION STRUCTURE OF HANDLE OF SPOON NET

摘要

PROBLEM TO BE SOLVED: To provide a connection structure of a handle of a spoon net to give a spoon net having excellent operability. SOLUTION: A tapered second pipe 12 is connected to a tapered third pipe 13 in a state to be put into the third pipe from its tip side. The third pipe 13 is composed of a small diameter part 20 formed by partly decreasing the inner diameter of the third pipe at the tip side and a pair of engaging protrusions 21 formed on the inner circumference of the near side adjacent to the small diameter part. The protrusions are separated by 180°in the circumferential direction, extended in axial direction and protruded in the pipe. The second pipe 12 has a large diameter part 22 having partly increased outer diameter and formed at the butt end of the rod. A plurality of engaging grooves are formed on the outer circumference of the large diameter part 22 in a manner extended in the axial direction and separated from each other in circumferential direction interposing a gap.
