The invention relates to a connecting component. The connecting component comprises a connecting core bar and a connecting sleeve, which are matched, wherein a connecting cavity is formed in the connecting sleeve; the connecting core bar comprises a columnar connecting section which is rotatably inserted into the connecting cavity during use; the diameter of the periphery of the connecting section is smaller than that of the periphery of a connecting seat; a stopping structure which is turned inwards is arranged in the connecting cavity; a stopping structure inner hole is formed on the stopping structure; the aperture of the stopping structure inner hole is the same as the diameter of the periphery of the connecting section; the connecting section is provided with a steel wire rope through hole which radially penetrates through the connecting section; a rope guide slot which is communicated with the connecting cavity and matched with the steel wire rope through hole is formed at a root of the connecting sleeve, which is close to the stopping structure; and a gap for accommodating a corresponding steel wire rope is formed between the wall of the stopping structure inner hole and the wall of the connecting cavity. The detachable connecting component is simple in structure, convenient to process and low in manufacturing cost. Other special tools are not required in the processes of connection, assembly and disassembly. The detachable connecting component is high in assembly and disassembly efficiency and convenient to use.
