DETAILED DESCRIPTION OF THE INVENTION

[0012] Preferred embodiments of the present invention are described with reference to the accompanying drawings, and it is to be understood that the preferred embodiments described herein are only for illustration purpose, and are not intended to limit the invention.

Embodiment 1

[0013] As shown in FIG. 1, the present invention provides a snake bone. The snake bone includes a plurality of structural units 100, each of the structural units 100 comprises a first connecting pipe (1) and a second connecting pipe (2). A slot (3) and a T-shaped structure (6) are provided on one end of the first connecting pipe (1); a clamping block (4) and a limiting slot (5) are provided on one end of the second connecting pipe (2); a limiting structure A (7) is provided on both sides of one end of the limiting slot (5), and the other end of the limiting slot (5) is provided with a limiting structure B (8); the clamping block (4) is located in the slot (3), and the T-shaped structure (6) is located in the limiting slot (5); a top end of the second connecting pipe (2) of the structural units (100) is connected with a bottom end of the first connecting pipe (1) of adjacent structural unit (100), thereby forming a curve tubular-shaped snake bone successively connected by the plurality of structural units (100).

[0014] The horizontal cross sections of the slot (3) and the clamping block (4) are circular, which reduces the resistance when the snake bone bends and makes it easier to bend. The horizontal cross sections of the slot (3) and the clamping block (4) are trapezoid so that the first connecting pipe (1) and the second connecting pipe (2) are not easily to be disjointed when connecting with clamping block (4) through the clamping block (4).

[0015] Specific working principle: 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 pin in the direction perpendicular to the bend. And the T-shaped structure 6 is designed to push the limiting position when it is bent to the limiting position, and further bending of the bones can be prevented, and the strength of the bending direction can also be increased. When the snake bone is flat, the T-shaped structure 6 has no effect. When the snake bone is bent, the two T-shaped structures are respectively close to the limiting structure A 7 and the limiting structure B 8; when the snake bone is bent to the limiting position, the T-shaped structure is pushed in place, and the strengthening effect begins to emerge.

[0016] The beneficial effect of the invention is that the snake bone strengthens the vertical bending direction strength of the snake bone by the T-type structure, compared with strip pin, the T-type structure is more effective and has little effect on the internal structure of the snake, and the strength of the bending direction of bone has also been strengthened.

[0017] It should be noted that the foregoing is only a preferred embodiment of the present invention and is not intended to limit the invention. Although the invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that the technical solutions described in the foregoing embodiments may be modified or equivalently replaced with some of the technical features therein. Any modifications, equivalent substitutions, improvements and the like within the spirit and principles of the invention are intended to be included within the scope of the present invention.
