1. A pipe binding mechanism, which connects a first pipe and a second pipe, both made of a synthetic resin material, comprising:
a rubber band which is formed in a ring shape penetrated longitudinally and is made of a flexible material capable of being in close contact with outer surfaces of the first and second pipes;
a tightening plate which is made of an elastic metallic material, configured to wrap connected ends of the first and second pipes in a circumferential direction and to wrap the rubber band from outside, and having both ends overlapping each other; and
a pair of pipe binding bands which are respectively disposed at both widthwise ends of the tightening plate and configured to adjust a close contact force relative to the outer surfaces of the first and second pipes; and
a plurality of rubber band pressure pins made of a metallic material, each comprising:
a pressure pin body extending in a longitudinal direction of the rubber band; and
a pair of pressure pin protrusions having both longitudinal ends inclinedly bent to be in contact with the outer surfaces of the first and second pipes,
wherein the plurality of rubber band pressure pins are spaced from each other in a circumferential direction and coupled to the rubber band, and both longitudinal ends of the plurality of rubber band pressure pins are inclinedly bent in a direction that the first and second pipes approach each other.
