摘要：
The present disclosure discloses a snake bone. The snake bone includes a plurality of structural units 100, each of the structural units 100 includes a first connecting pipe and a second connecting pipe. One end of the first connecting pipe is provided with a slot and a T-shaped structure, a clamping block and a limiting slot are provided on one end of the second connecting pipe. A limiting structure A is provided on both sides of one end of the limiting slot, and the other end of the limiting slot is provided with a limiting structure B. The clamping block and the T-shaped structure are located in the limiting slot, two flanks are provided on the original pin to form a T-shaped structure 6, other positions keep clearance. When the snake bone bends to the limiting position, the T-shaped structure 6 stucks or pushes against the limiting position. First of all, the T-shaped structure 6 is a pin in nature, which can strengthen the strength perpendicular to the bending direction. Secondly, in the structure of the snake bone with a pin, when the bones are broken perpendicularly to the bending direction, the pin is bent firstly, then the pin is disengaged, and finally the snake bone is broken, and the T-shaped structure makes it difficult to disengage the pin, thereby increasing the strength of the snake bone perpendicular to the bending direction. The plurality of structural units 100 are successively connected to form a curve tubular-shaped snake bone.
