BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an exercising device, and more particularly to an exercising elastic pull cord. [0003] 2. Description of the Related Art [0004] A conventional exercising elastic pull cord 4 in accordance with the prior art shown in FIGS. 5-8 comprises an elastic pull cord body 41 having two distal ends each provided with a handgrip 42, an urging body 5, and a sleeve 6. The handgrip 42 has an end face having an inside formed with a catch flange 421 rested on the sleeve 6. The urging body 5 is inserted into the elastic pull cord body 41 to press the elastic pull cord body 41 and the sleeve 6 outward so that the sleeve 6 has a protruding stop portion 61 rested on the catch flange 421 of the handgrip 42 to secure the sleeve 6 to the handgrip 42, thereby preventing the sleeve 6 from being detached from the handgrip 42. [0005] When the handgrip 42 is moved outward relative to the elastic pull cord body 41, the catch flange 421 of the handgrip 42 is rested on the stop portion 61 of the sleeve 6, so that the elastic pull cord body 41 is pulled outward by the handgrip 42. Thus, when the elastic pull cord body 41 is pulled outward by the handgrip 42, the elastic pull cord body 41 is driven by the handgrip 12 to slip toward the tensile direction of the elastic pull cord body 41 from the urging body 5. [0006] However, the elastic pull cord body 41 is deformed by the tensile action of the elastic pull cord body 11, and the thickness of the elastic pull cord body 41 is reduced, so that the elastic pull cord body 41 is easily detached from the sleeve 6 and the handgrip 12. In addition, when the sleeve 6 is broken or worn out during a long-term utilization, the elastic pull cord body 41 is rubbed by the handgrip, thereby wearing the elastic pull cord body 41. Further, the elastic pull cord body 41 will spring outward accidentally when being broken or worn out, thereby causing danger to a user's when using the exercising elastic pull cord. SUMMARY OF THE INVENTION [0007] In accordance with the present invention, there is provided an exercising elastic pull cord, comprising 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. [0008] The primary objective of the present invention is to provide an exercising elastic pull cord, wherein 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. [0009] Another objective of the present invention is to provide an exercising elastic pull cord, wherein the fabric outer layer of the elastic pull cord body is coated around the elastic inner tube to prevent the elastic inner tube of the elastic pull cord body from being rubbed by the handgrip so as to enhance the lifetime of the elastic pull cord body. [0010] A further objective of the present invention is to provide an exercising elastic pull cord, wherein the elastic inner tube of the elastic pull cord body is coated by the fabric outer layer, so that when the elastic inner tube of the elastic pull cord body is broken or worn out during a long-term utilization, the elastic inner tube of the elastic pull cord body will not spring outward accidentally so as to protect a user's safety when using the exercising elastic pull cord. [0011] Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS [0012] FIG. 1 is an exploded perspective view of an exercising elastic pull cord in accordance with the preferred embodiment of the present invention; [0013] FIG. 2 is a partially perspective assembly view of the exercising elastic pull cord as shown in FIG. 1; [0014] FIG. 3 is a perspective assembly view of the exercising elastic pull cord as shown in FIG. 2; [0015] FIG. 4 is a plan cross-sectional view of the exercising elastic pull cord as shown in FIG. 3; [0016] FIG. 5 is an exploded perspective view of a conventional exercising elastic pull cord in accordance with the prior art; [0017] FIG. 6 is a partially perspective assembly view of the conventional exercising elastic pull cord as shown in FIG. 5; [0018] FIG. 7 is a perspective assembly view of the conventional exercising elastic pull cord as shown in FIG. 6; and [0019] FIG. 8 is a plan cross-sectional view of the conventional exercising elastic pull cord as shown in FIG. 7. DETAILED DESCRIPTION OF THE INVENTION [0020] Referring to the drawings and initially to FIG. 1, an exercising elastic pull cord 1 in accordance with the preferred embodiment of the present invention comprises an elastic pull cord body 11 having an elastic inner tube 111, and a fabric outer layer 112 coated around an outer periphery of the elastic inner tube 111. The fabric outer layer 112 of the elastic pull cord body 11 is formed by a cylinder knitting machine. The elastic inner tube 111 of the elastic pull cord body 11 has an elastic coefficient greater than that of the fabric outer layer 112. Continue reading about Exercising elastic pull cord...
