Claims

[Scope of utility model registration request]

One side of the outer link part of the opposing offset-type link part is fixed to both sides of the support stay part, and the frame-shaped link formed by attaching the opening/closing stay part to the other side is connected so as to be bendable to each other at the offset-type link part. , the front part of the outer link part, the support stay part, and the opening/closing stay part in the closed position is formed into a convex cylindrical surface centered on the connecting hole provided in the outer link part, and the connecting hole is surrounded on the inside of the outer link part. Provide a recess that opens forward by bending.
The inner link part of the offset type link part forms a flexible tongue piece that slides into the recess, and has a protruding pin part on the outside of the rear part that is inserted into the connecting hole, and the outer link part and the support stay part are connected to each other. A concave cylindrical surface with a slightly larger diameter than the convex cylindrical surface is formed at the rear of the opening/closing stay part in the position, with the protruding pin part as the center, and when the protruding pin part is inserted into the connecting hole, the recess and the flexible tongue It can be bent between the position where the frame-shaped link forms a straight line due to side contact with the piece and the predetermined angular position where the adjacent front and rear opening/closing stay parts maintain overlap, and is formed on both sides of the opening/closing stay part. A closed type cable drag chain that can be opened and closed, characterized in that a hook elastically engages with a recess in the outer link part and is tightly fixed to the outer link part.
