         19 : Manufacturing method of an adjustable shoulder strap, comprising steps:
 A. Stitching and securing one end of a strap body to a fixed column of a brassiere strap adjustment ring on the rear side of said brassiere strap adjustment ring using stitching;   B. Passing the other end of said strap body from said rear side, on one side of said fixed column, through a frame body to the front side of said brassiere shoulder strap adjustment ring;   C. Passing the other end of said strap body from said front side, on the other side of said fixed column, through said frame body to said rear side.   
     
     
         20 : The manufacturing method of an adjustable shoulder strap, as recited in  claim 19 , wherein said manufacturing method of an adjustable shoulder strap, before said step A, further comprises a step of stamping to form said brassiere strap adjustment ring, wherein said brassiere strap adjustment ring comprises said frame body and said fixed column, wherein said frame body is defined to have a threading space, and wherein said fixed column is horizontally placed in said frame body, dividing said threading space into a first guiding hole and a second guiding hole, wherein said fixed column has at least one threading hole aligned with the opening direction of said first guiding hole and said second guiding hole. 
     
     
         21 : An adjustable shoulder strap, comprising:
 a strap body comprising a fixed end and a connecting end opposite to said fixed end;   a brassiere strap adjustment ring, comprising a frame body and a fixed column horizontally placed in said frame body to form a first guiding hole and a second guiding hole, wherein said fixed column, which is located between said first guiding hole and said second guiding hole, has a plurality of threading holes; and   a stitching which connect said fixed column with said fixed end of said strap body, wherein said fixed end of said strap body is stitched and secured to said fixed column on one side of said brassiere strap adjustment ring by threading through said plurality of threading holes and said first guiding hole with said stitching, wherein said stitching comprises a plurality of first stitching thread portions each passing through one of said plurality of threading holes and said first guiding hole, and a second stitching thread portion between two adjacent first stitching thread portions of said plurality of first stitching thread portions, wherein each said second stitching thread portion passes through two adjacent threading holes of said plurality of threading holes;   wherein said connecting end is adapted to sequentially pass through said second guiding hole and said first guiding hole of said frame body.   
     
     
         22 : The adjustable shoulder strap according to  claim 21 , wherein said fixed column has a hole frame defining each of said plurality of threading holes, wherein said hole frame comprises a first side, a second side, a third side, and a fourth side, wherein said first side, said second side, said third side, and said fourth side are connected end-to-end sequentially. 
     
     
         23 : The adjustable shoulder strap according to  claim 22 , wherein said first side, said second side, said third side, and said fourth side are connected end-to-end sequentially to form two first connecting positions which are spacedly arranged along an extending direction of the corresponding first stitching thread portion and two second connecting positions which are spacedly arranged along an extending direction of the corresponding second stitching thread portion. 
     
     
         24 : The adjustable shoulder strap according to  claim 23 , wherein said extending direction of the corresponding first stitching thread portion is vertical, said extending direction of the corresponding second stitching thread portion is horizontal.
