[0027] Specifically, by pressing the seven-shaped plate 22, the torsion spring 23 can be rotated, thereby facilitating the rapid installation of the cable. The torsion spring 23 automatically resets, thereby limiting the cable through the seven-shaped plate 22, and the pin 2 can be removed by pulling out the cotter pin 21.
