[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0020] Please see Figures 1-4 In this embodiment of the invention, a balance ring-type string hanger on an eccentric wheel of a composite bow includes an eccentric wheel 1. A connector 3 is mounted on the eccentric wheel 1, and the connector 3 and the eccentric wheel 1 are detachably connected (generally by a threaded connection). A string hanger sleeve 2 is fitted onto the connector 3, and the string hanger sleeve 2 can rotate on the connector 3, allowing... Figure 5 The tension of the bowstring on both sides of the same string is nearly uniform, and the presence of the string post makes the adjustment process of uniform string tension automatic, with uniform rebound speed, so the driven ball bearing is subjected to more precise force.
