Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, and for example, "connected" may be either fixedly connected or detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

An abrasion-proof traction ring comprises an upper rod body 1, a connecting rod 4 and a lower rod body 5; the upper end of the upper rod body 1 is provided with a clamping ring 2, and the lower end of the upper rod body is clamped and embedded in the connecting rod 4; the upper end of the lower rod body 5 is fixedly connected with the connecting rod 4, and the lower end of the lower rod body 5 is provided with a check ring 11; a rotating ring 3 is arranged in the clamping ring 2; an external thread structure is arranged outside the lower rod body 5; and a hexagonal nut 8 is arranged on the external thread structure of the lower rod body 5.

The lower end of the upper rod body 1 is provided with a sliding block matched with the inner diameter of the connecting rod 4; and a first pressure spring 6 and a second pressure spring 7 are respectively arranged at two ends of the sliding block. Through the structural connection relation of the upper rod body 1, the connecting rod 4 and the lower rod body 5 and the matching use of the first pressure spring 6 and the second pressure spring 7, the problem of overlarge impact force can be effectively solved through the first pressure spring 6 and the second pressure spring 7 no matter when tension or thrust is applied.
