The proportion range of the thickness to the width of the flat body of the variable-diameter sheath is 1: 4-1: 2, so that the bending resistance can be effectively improved while the internal cable is effectively stored, the cable is protected, and abrasion is avoided.

The inner diameter of the variable-diameter sheath is smaller than that of the tail accessory, so that contact abrasion of a lead at a tail accessory leading-out end when the thick end is bent after the machine is installed can be effectively avoided.

The variable-diameter sheath is a rubber sleeve or a composite material sleeve or a plastic sleeve, and the clamping wires are round metal wires, so that the sheath is effectively fixed.

The wire is of an independent structure and is arranged in a bending mode, and the centrifugal force of the sheath can be effectively prevented from being transmitted to the wire.

Be provided with the encapsulating hole on the tail annex, this encapsulating hole is close to the plug and communicates inside cavity to it is fixed effectively to carry out the veneer to inside cable conductor, avoids inside too much inflow sheath simultaneously.

The tail accessory and the sheath are provided with annular groove structures for butt joint, and the internal thread structures for butt joint are arranged at the plug, so that the cable is integrally and effectively fixed, and the structural stability is guaranteed.

And a plurality of anti-loosening screws are arranged at the connecting end of the tail accessory and the plug.

The invention has the technical effects that: according to the invention, by adopting the design of the variable-diameter sheath on the cable, the protection performance of the cable can be effectively improved, so that the cable can reliably transmit power and signals under the working condition of rotating along with the paddle, and the cable has the characteristics of simple structure, good manual assembly, high reliability and independent replacement.
