Abstract

The invention relates to a reflex bow, in particular to a folding type adjustable-tension reflex bow. The reflex bow comprises a bow handle, two bow arms, two folding bow arms and a bowstring. The twoends of the bow handle are each fixedly connected with one bow arm. The outer ends of the two bow arms are each in hinged connection with one folding bow arm. Each folding bow arm comprises a foldingbow arm body, a bowstring connection slide block and a fastening screw, wherein the bowstring connection slide block is in sliding connection with the folding bow arm body, and the fastening screw isused for clamping and fixing the folding bow arm body and the bowstring connection slide block. One end of the bowstring is fixedly connected with the bowstring connection slide block of one foldingbow arm, and the other end of the bowstring is fixedly connected with the bowstring connection slide block of the other folding bow arm. According to the compound bow capable of being carried in a folding mode, the bow can be folded, and the tension of the bowstring can be adjusted according to using or folding requirements; and the shape of the bow handle, the two bow arms and the two folding bowarms which are unfolded is fixed through the bowstring, and folding and unfolding use is facilitated.
