This creative department provides a hook, whose main features include a main body, wherein the main body is mainly composed of an upper hook portion, a connecting portion and a lower hook portion； The inner edge of the upper hook portion forms a channel, one end of the upper hook portion approaches to the side of the engaging portion and is laterally opposite to the engaging portion, and the channel forms an entrance between the end of the upper hook portion and the engaging portion, the entrance The width of the channel is smaller than the maximum radial width of the channel, which makes it difficult for the main body to be detached after being installed on a rod body. A virtual plane is defined to be opposite to the joint portion, and the extending direction of the joint portion is orthogonal to the plane. The orthographic projection of the lower hook portion and the upper hook portion on the plane forms an included angle.本創作係提供一種掛鉤，其主要特點包括一主體，其中該主體主要由一上鉤部、一銜接部及一下鉤部銜接構成；；該上鉤部內緣形成通道，該上鉤部一端向著該銜接部的一側接近，並與該銜接部側向相對，且該通道於該上鉤部的末端與該銜接部之間形成一入口，該入口的寬度小於該通道之最大徑向寬度，據使該主體設置於一桿體後不易脫離；定義一虛擬之平面與該銜接部相對，且該銜接部的延伸方向與該平面形成正交，該下鉤部及該上鉤部於該平面之正投影形成一夾角。；
