In-Tube Fixing Assembly

Abstract

An in-tube fixing assembly, which fixes an object inside or at an end of a tube, includes a primary tube having an inner space and an inner wall defining the inner space; a fixing member inserted partially or wholly into the inner space from an opened end of the primary tube and provided with at least one through hole at an appropriate position, the through hole provided with an accommodation part extending in a direction from the through hole toward the inner wall of the primary tube by a predetermined angle; and at least one screw member, one end of which is defined as an operation end and the other end defined as an insertion end, a diameter of the screw member configured to gradually decrease from the operation end to the insertion end, wherein the screw member is inserted into the through hole in a direction from the opened end to the inner space of the primary tube, such that when the insertion end is rotatably inserted into the accommodation part from the through hole, the insertion end of the screw member abuts against the inner wall of the primary tube to form a small recess thereon, the small recess and the accommodation part respectively form a first engaging thread and a second engaging thread, that are complementary to a shape of the screw member.
