Variable-diameter multifunctional cable connector and working method thereof

The invention discloses a variable-diameter multifunctional cable connector and a working method thereof, and belongs to the technical field of cable connectors. A cable clamping seat is slidably mounted in the cable connector, an S-shaped wire groove is formed in the cable clamping seat, an S-shaped anti-skid clamping piece is mounted in the wire groove, and a cable is clamped between the anti-skid clamping piece and the wire groove; when the cable vibrates or bears axial force, the unique clamping path can offset the axial force borne by the cable, meanwhile, the influence of vibration on the insulation layer at the extrusion position is reduced, firm installation is achieved, meanwhile, vibration abrasion caused by existing linear installation is avoided, and the service life of the cable is prolonged. Meanwhile, the distance between the anti-skid clamping piece and the wire groove is adjusted through the telescopic adjusting piece, stable and firm installation can be achieved for cables with different dia
