7. A method for using an elevator cable according to any one of claims 1 to 6, characterized in that: The following steps are involved: S1: First, the staff fits the outer sides of several fitting wheels (11) to the outer sides of the elevator cables (10), and splices two adjacent mounting plates (13), and then starts to activate the external device to drive the pull rope (9) to rotate. When the pull rope (9) starts to be lowered, the fixed box (1) moves synchronously with the pull rope (9) to the bottom; S2: When the fitting wheel (11) moves downward, the fitting wheel (11) can rotate by friction with the outer side of the elevator cable (10). When the fitting wheel (11) rotates, the circular shaft can be driven to rotate. When the circular shaft rotates, the rotating gear (19) can be driven to rotate. When the rotating gear (19) rotates, the rotating plate (20) located at the rear side can be driven to rotate by meshing with a plurality of rotating rods (22). When the rotating plate (20) located at the rear side rotates, the transmission gear (24) located at the rear side can be driven to rotate through the adjacent short rods (23). When the transmission gear (24) located at the rear side rotates, the rotating plate (20) located at the center can be driven to rotate. When the rotating plate (20) located at the center rotates, the transmission gear (24) located at the front side can be driven to rotate through the adjacent short rods (23). When the transmission gear (24) located at the front side rotates, the rotating plate (20) located at the front side can be driven to rotate. S3: When the rotating plate (20) located at the center rotates, the adjacent bonding plate (21) can be driven to rotate. When the bonding plate (21) located at the rear side rotates to move the start trigger plate (18), it can represent that the fixed box (1) falls to a predetermined distance, and the upper motor (7) and the lower motor (6) are started, and the external device is temporarily turned off. When the upper motor (7) is started, the power output shaft can drive the rotating shaft (34) to rotate. When the rotating shaft (34) rotates, it can drive the guide wheel (35). When the guide wheel (35) rotates, it fits with the slider (37) through the guide groove, thereby driving the U-shaped plate (36) to move back and forth. When the U-shaped plate (36) moves back and forth, it can drive the moving frame (40) to move back and forth. When the moving frame (40) moves, it can drive a plurality of cable fixing plates (15) to move toward the rear side, thereby making the cable fixing plate (15) located at the front side fit with the elevator cable (10), and the elevator cable (10) is also fit on the hoistway wall; S4: When the lower motor (6) is started, the central gear (5) can be driven to rotate. When the central gear (5) rotates, the two driven gears (2) can be driven to rotate. When the two driven gears (2) rotate, the two threaded tubes (4) can be driven to rotate. When the two threaded tubes (4) rotate, a plurality of special fixing bolts (38) can be driven to move to the rear side, thereby installing the cable fixing plate (15) on the hoistway wall, thereby fixing the elevator cable (10).
