Claim:
1. A single-detent binder comprising: a housing provided with a closed longitudinal end and an open longitudinal end; at least one pair of baseplates, wherein said baseplates of said one pair of baseplates are longitudinally adjacent and parallelly arranged and connected to each other, wherein said one pair of baseplates comprises adjacent longitudinal edges and non-adjacent longitudinal edges; one or more ring shaped components, wherein said ring shaped components each comprise two half ring shaped elements, said half ring shaped elements each are fixed on said one pair of baseplates and pass through said housing, said half ring shaped elements occlude to form a closed ring, and said half ring shaped elements disjoin to form an opened ring; wherein said one pair of baseplates is so assembled as to pivot around said adjacent longitudinal edges in order to open or close said ring shaped components, and said non-adjacent longitudinal edges of said one pair of baseplates abut upon an inner side of said housing; a control component comprising (i) a handle, which enables said control component to rotate relative to said housing, (ii) an upper extension arm, (iii) a lower extension arm provided with a pivot pin, so that said control component pivots around a pivot axis that coincides with the pivot pin, and (iv) a groove connected to one longitudinal end of said baseplates; an intermediate junction component, wherein one end of said intermediate junction component is connected to said upper extension arm, and the other end of said intermediate junction component is connected to a pull rod; wherein said pull rod is provided with an elongate main rod and a connection end, wherein said connection end is connected to said intermediate junction component; wherein said single-detent binder also comprises one or more rotary locking pieces and one or more baffle plates on said one baseplate; one end of the upper surface of said rotary locking piece is rotatively connected to said one baseplate, and the other end of the lower surface of said rotary locking piece is rotatively connected to said pull rod; and wherein said intermediate junction component is positioned between the housing and at least one of the baseplates and is close to the open longitudinal end.
