When the cable encounters tension, the curved arc structure of the bending and rotating frame 14 can adapt to the tension and undergo a certain deformation, thereby providing a buffer space for the movement of the cable, that is, the pulling length is the reserved cable length, so as to protect the cable from being pulled and damaged or the cable and the power interface from becoming loose.
