发明名称 Exercising elastic pull cord
摘要 An exercising elastic pull cord includes an elastic pull cord body having an elastic inner tube, and a fabric outer layer coated around an outer periphery of the elastic inner tube. The elastic pull cord body has two distal ends each provided with a handgrip, an urging body, and a contraction sleeve. Thus, the elastic inner tube of the elastic pull cord body is not deformed by the tensile action of the elastic pull cord body, so that the contraction sleeve mounted around the elastic pull cord body is secured to the handgrip closely, thereby preventing the handgrip from being detached from the respective distal end of the elastic pull cord body.
