Defensively anti-strain method and apparatus

The invention discloses a defensively anti-strain method and apparatus, and the apparatus comprises an annular body that has multiple bearing segments, inclining segments and groove segments, wherein, the inclining segments are arranged by intervals in order; the apparatus also comprises a buried rubber shock connector or a rubber soft shock absorber, and a water sealer like a waterproof washer or an O-shaped ring. According to the defensively anti-strain method and apparatus, water preventing and waterproof functions are realized; the rubber is prevented from aging or from breaking under outside pressure effectively; a steel rope is replaced and bad influence like the steel rope breaking into steel wire to cut the rubber because of being squeezed; water preventing and waterproof functions are enhanced; and the rubber shock connector or the rubber soft shock absorber, and the water sealer like the waterproof washer or the O-shaped ring are prevented from distortion or breaking because of strain generated by l
