Abstract:
A fixing structure of a paddle having an outer tube, an inner tube and a tightening means for tightening the outer tube and inner tube; the tightening means being formed by a positioning ring at one end portion of the outer tube and an engaging portion at one end portion of the inner tube; the positioning ring being buckled to the engaging portion;one end portion of the positioning ring is protruded with an eccentric buckle, and one end of the buckle is protruded with an elastomer; the elastomer is pushed and pulled so that the elastomer is engaged in an eccentric embedded hole of the engaging portion; an interior of the engaging portion has an eccentric embedding hole and an inner edge of the embedding hole is formed with a stepped edge for resisting against an buckle piece of the positioning ring; when the engaging portion rotates, a part of circular edge of the position ring will protrude out of the circular edge of the engaging portion so that the diameter thereof will expand to tightly resist against the outer tube; characterized in that: the annular side of the position ring is formed with irregular buckling textures; the buckling textures are a plurality of small particles so that the position ring substantially resists against an inner side of the outer tub; thereby, the outer tube tightly resists.
