Claim:
A joint structure for a cable comprising: a connecting sleeve formed in an annular tube shape, and including threads formed around an inner wall of an opening of an upper end thereof, and including a shoulder extending around a bottom end of the inner wall thereof; an internal tube fitted to the connecting sleeve and formed in a hollowly elongated tube shape, and including an arresting ring extending outward around an upper end thereof to abut against the shoulder of the connecting sleeve, and including a circular groove arranged around an outer wall thereof; an outer fitting member being a hollow housing, and including an orifice formed on a bottom end thereof, and including a hole disposed on a top surface thereof, the hole including a circular projection formed around an inner surface thereof to correspond to the circular groove of the internal tube such that the outer fitting member is fitted to the outer wall of the internal tube by using the hole and further enable to rotate the connecting sleeve; a sheath member formed in a tube shape and used to plug into the orifice of the bottom end of the outer fitting member and inserted into the outer fitting member, including an arrest rib extending around a bottom end thereof to correspond to the bottom end of the outer fitting member, and including a threaded section mounted around an inner wall thereof; a stopping loop fixed on a top end of the sheath member and formed in a hollowly circular tube shape, including a plurality of resilient paws radially arranged around an upper end thereof and spaced apart from each other, the resilient paws being titled inward; a screwed sliding member formed in an elongated tube shape, including one end inserted into the sheath member and the stopping loop, including a screwed portion disposed around an outer wall thereof to screw with the threaded section of the sheath member so as to slide in the sheath member and the stopping loop, and when the screwed sliding member slides, it allows to selectively push the resilient paws of the stopping loop so that the resilient paws are expanded outward.
