Abstract
A multi-ring binder includes a positioning lock pin, a movable central spindle, a first bracket, a second bracket and a C-ring. The movable central spindle is formed by a plurality of cylindrical bodies and a plurality of rectangular bodies staggered, and the top of the movable central spindle is connected to the positioning lock pin and the surface of the rectangular body next to the top has a first positioning groove and a second positioning groove. The first bracket has first half-rings arranged equidistant from each other, and first hollow bodies arranged equidistant from each other. The second bracket is complementary and symmetrical with the first bracket, and has second half-rings arranged equidistant from each other, and second hollow bodies arranged on equidistant from each other.

A multi-ring binder used in a loose-leaf notebook with multiple loose-leaf pages, comprising:
- a positioning lock pin;
- a movable central spindle comprising a main body formed by alternatively connecting a plurality of cylindrical bodies and a plurality of rectangular bodies in a line and a body top located on a top side of said main body and connected to said positioning lock pin, the said rectangular body adjacent to said body top comprising a first positioning groove and a second positioning groove, said movable central spindle being drivable to move by said positioning lock pin;
- a first bracket comprising a plurality of first half-rings and a plurality of second half-rings staggered and arranged thereon at equal distances from each other and a plurality of first hollow bodies and a top hollow body arranged thereon at appropriate intervals, the shapes of said first hollow bodies and said top hollow body being both outer circle and inner square;
- a second bracket, said second bracket and said first bracket being substantially complementary symmetrical, said second bracket comprising a plurality of first half-rings and a plurality of second half-rings staggered and arranged thereon equidistantly from each other and a plurality of second hollow bodies and a bottom hollow body arranged thereon at appropriate intervals, the shapes of said second hollow bodies and said bottom hollow body being both outer circle and inner square, the shapes and positions of said second half-rings corresponding to said first half-rings;
- and
- a C-ring connected to said first bracket;
- wherein through the symmetrical engagement of said first bracket and said second bracket, said first hollow bodies and said second hollow bodies are joined to each other to form a continuous hollow body, and said movable central spindle is arranged in said continuous hollow body to serve as the common central axis of rotation of said first bracket and said second bracket, and the external shape of said continuous hollow body is an outer circle and an inner square.
