Orthosis device and thread-guiding structure thereof

A thread-guiding structure, for being disposed on an orthosis device, including:

• a base, having at least three recesses integrally formed thereon and a plurality of connecting bridges integrally formed thereon, each of the at least three recesses having an inner wall having a first restriction structure, every adjacent two ones of the at least three recesses being integrally connected with one of the plurality of connecting bridges;
• at least three guiding members, each of the at least three guiding members defining an axis, including a guiding groove arcuately disposed about the axis and a second restriction structure which are integrally formed, each of the at least three guiding members received in one of the at least three recesses and positionably restricted with blocking of the second restriction structure of one of the at least three guiding members and the first restriction structure of one of the at least three recesses, each guiding groove and one of the inner wall of the at least three recesses defining a thread-penetrating passage therebetween, each of the at least three guiding members being freely bidirectionally rotatable;
• wherein the first restriction structure includes a first lower annular protrusion integrally projecting axially from a bottom portion of the recess, the first lower annular protrusion has a first lower flange integrally protruding radially, the second restriction structure includes a second lower annular protrusion integrally projecting from a bottom portion of the guiding member, the second lower annular protrusion has a second lower flange integrally protruding radially, and the first and second lower flanges protrude toward opposite directions and are abuttable against each other axially.
