Insulators, commonly known as porcelain bottles, are insulators used to support wires. The insulator can ensure that the wire, the cross arm and the tower have enough insulation, and is used for bearing the load of the wire in the vertical direction and the pulling force of the wire in the horizontal direction during the operation of the line, and the wire can ensure the stable operation of the line only if the wire is firmly fixed on the insulator. In recent years, due to the fact that mountains and large ditches in partial areas are deep, the environment of a route is severe, large span is large, the phenomena of wire binding fracture and falling of a plurality of base rod bases occur, wires fall off or fly from porcelain bottles due to wire binding fracture, the phenomena of short circuit, line grounding or tripping power failure are easily caused, and the safe and stable operation and the power supply reliability of the line where the wires are located are seriously influenced.

The existing binding fixing mode is mostly a binding type, a wire is embedded into a needle bottle top groove, a binding wire is twisted along the wire to form a winding at the position close to the needle bottle on the left side of the wire, and a certain length is reserved at one end of a binding short head. This approach has a number of drawbacks: 1. the fixing process is manual operation, so that the phenomenon of uneven stress distribution of the binding wire is easily caused in the fixing process, and the fixing is not firm due to over-tightness and over-tightness; 2. the binding wires and the conducting wires are exposed outdoors directly, and the binding wires are easy to loosen or break under the action of long-term sunlight and wind; 3. when the lead is fixed or replaced, the power is cut off, which causes great inconvenience. In the patent application with the application number of 201910630052.X, a combined porcelain bottle clamp is provided, which structurally comprises an upper shell and a lower shell; go up the casing and pass through the bolt and will descend the casing to sticis on the cable at vase top, the whole body adopts reinforcing nylon PA6 to reduce weight and cost. Although this technical scheme has made certain progress in comparing in traditional bundle line fixed mode, the operation mode convenience of fastening through the screw is relatively poor, and this scheme is not good enough to the antiskid nature consideration between device and the wire when fixed cable, easily causes the damage to the wire.
