By calculating the wire diameter ratio of the power cable and the signal cable, the required rope capacity of the two is obtained, and then the corresponding position that needs to be moved is obtained, and a reasonable rope capacity is adjusted. The screw drive assembly (340) is started to drive the turntable base (310) to move back and forth along the screw axis. The turntable base (310) is connected to the cable assembly mounting frame (440) so that the first screw drive assembly (450) and the second screw drive assembly (460) installed on the upper part can be driven to move synchronously when the turntable base (310) moves. The two fixed seats of the two screws are respectively connected to the slide in the slide rail assembly (431); S2, the action of the protection mechanism after the winding encounters an obstruction. When winding, when one or both of the two cables are restrained by foreign objects, the pulling force of the first synchronous belt will increase, thereby overcoming the pressure of the elastic shaft seat (552) and causing the movable shaft (54a2) to move upward along the shaft mounting portion (551). After the pressure of the elastic shaft seat (552), the movable shaft (54a2) enters the lower position of the shaft mounting portion (551). After the movable shaft (54a2) enters the lower position of the shaft mounting portion (551), the second synchronous belt is in a failure state, and the winding stops at this time; S3. Reset. When the obstruction protection mechanism (550) is in the disconnected state, that is, when the movable shaft (54a2) falls on the lower part of the shaft mounting portion (551), the reset knob (t7) is turned to reset. The reset knob (t7) pushes the push block (t5) to overcome the tension of the two reset springs (t9) and move forward until its inclined surface contacts the movable shaft (54a2). The push block (t5) is further rotated to push the movable shaft (54a2) forward. At this time, the guide shaft (t6) is guided by the guide rail (d1) and the inclined waist hole (554) so ​​that the push block (t5) is tilted upward as a whole, thereby moving the movable shaft (54a2) upward until the movable shaft (54a2) re-enters the upper part of the shaft mounting portion (551) to complete the reset. Then, the reset knob (t7) is turned in the opposite direction to return the push block (t5) to the initial position.
