[0003] The existing composite bow on the market, such as the composite bow handle and composite bow disclosed in patent CN116447919A, includes bow pieces, bow seats, bow wheels, and adjusters, and the bow seats are symmetrically arranged at both ends of the bow handle, two bow pieces are fixed on each bow seat by a detachable method, the two bow pieces on the same bow seat are symmetrically arranged, and the positions between the two bow pieces on the same bow seat are provided with bow wheels, the bow wheels are rotatably connected with the end portions of the bow pieces through shafts, and the inner sides of the bow wheels are provided with adjusters, and a drawstring is arranged on each adjuster. As can be seen, the bow pieces are installed on the bow handle through the bow seats, so the installation state of the bow pieces on the bow handle can be adjusted through the bow seats to achieve the adjustment of the tightness of the bowstring, which is called pound adjustment in the industry. In addition, the structure of the existing bow seat, such as the composite bow piece adjusting structure disclosed in patent CN217877320U, has a limiting piece arranged on each side of the adjusting seat (the above-mentioned bow seat) and rotatably installed on the bow arm (the above-mentioned bow handle), and a fixed hole is arranged on the adjusting seat, the adjusting seat is fixed on the composite bow arm through the fixed hole, and a connecting screw is arranged in the fixed hole, the other end of the connecting screw is connected to the bow arm, so that when the connecting screw is twisted, the adjusting seat can be deflected through the hinge point of the limiting piece, thereby adjusting the angle at which the adjusting seat is installed on the bow arm. At this time, since the bowstring is installed on the adjusting seat through the bow pieces and the bow wheels, the bow wheels and the fixed hole are located on the two sides of the hinge point of the adjusting seat on the bow arm, forming a lever structure, so that in the case that the bowstring is tight, the fixed hole will be subjected to a force away from the bow arm, causing the connecting screw to bear a large pulling force, thereby requiring a very large force to twist the connecting screw during subsequent pound adjustment, and the convenience of use is poor. In addition, since the connecting screw directly presses against the adjusting seat, the two are in direct contact, which causes direct friction between the two during pound adjustment, and is prone to wear and tear, which affects the accuracy of subsequent pound adjustment, shortens the service life of the structure, and also causes debris generated by wear and tear to enter the threaded fitting of the connecting screw, accelerating the wear of the threads and further shortening the service life.
