1. A cable protection and guide device for protecting and guiding a cable in a cable inserting space, comprising:

  • a number of adjacent longitudinal link bodies each articulably interconnected;

    each of said link bodies includes a bending center point;

    each of said link bodies includes a pair of left and right side plates;

    each of said side plates includes an upper edge center portion, a lower edge center portion, an end side and another end side;

    a connecting plate is laterally bridged over said upper edge center portion and said lower edge center portion of said right and left side plates;

    each of said side plates includes a convex connecting pin piece provided on said an end side of said side plate;

    each of said side plates includes a concave connecting pin hole provided on said another end side of said side plate;

    each of said convex connecting pin pieces of each of said side plates being articulably interconnected to a respective adjacent concave connecting pin hole of said adjacent link body;

    each of said convex connecting pin pieces of said side plates includes a pair of upper and lower stopper surfaces which are parallel to said upper edge center portion and said lower edge center portion and oppositely disposed about said bending center point of said adjacent link bodies;

    each of said connecting pin pieces includes a pair of front and rear arc-shaped outer circumferential surfaces joining said stopper surfaces and being oppositely disposed about said bending center point of said adjacent link bodies;

    each of said connecting pin holes includes a pair of arc-shaped inner circumferential surfaces;

    each of said connecting pin holes includes a pair of inner linear position maintaining surfaces which are parallel to said upper edge center portion and said lower edge center portion of said side plates and are oppositely disposed about said bending center point of said adjacent link bodies simultaneously abutting said pair of upper and lower stopper surfaces of said respective connecting pin pieces;

    each of said connecting pin holes includes inner bending limiting surfaces which are formed at a bending limiting angle with respect to said linear maintaining surfaces and are oppositely disposed about said bending center point of said adjacent link bodies simultaneously abutting said pair of upper and lower stopper surfaces of said respective connecting pin pieces; and

    , each of said pair of arc-shaped inner circumferential surfaces oppositely disposed about said bending center point being rotatably in sliding contact with said pair of front and rear arc-shaped outer circumferential surfaces of said connecting pin pieces.
