Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples, wherein the terms "upper", "lower", "left", "right", "inner", "outer", and the like, as used herein, refer to an orientation or positional relationship indicated in the drawings, which is for convenience and simplicity of description, and does not indicate or imply that the referenced devices or components must be in a particular orientation, constructed and operated in a particular manner, and thus should not be construed as limiting the present invention. The terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

A method for positioning a snake bone structure comprises the following steps:

1) providing a plurality of hollow snake bone components which are connected in sequence;

2) enabling two adjacent snake bone components to rotate relatively;

3) any snake bone component can be limited to the adjacent snake bone component after rotating a certain angle.

In order to enable the snake bone structure to rotate 360 degrees, namely when one snake bone component in two adjacent snake bone components rotates along the left-right direction, the other snake bone component can rotate along the up-down direction, the snake bone structure also comprises the following steps:

4) the rotation planes of two adjacent snake bone components are perpendicular to each other.

As shown in fig. 1 to 8, the above positioning method of the snake bone structure can be realized by a snake bone structure which comprises eight snake bone components connected in sequence, wherein the limit bulge 14 of one snake bone component is connected with the limit hole 12 of the other snake bone component. In other embodiments, the number of snake bone components is more than two.

The snake bone component comprises a tubular snake bone body 10, wherein the snake bone body 10 is hollow inside and is used for ventilating and placing cables.

One end of the snake bone body 10 is provided with two opposite extending parts 11, and the two extending parts 11 are provided with corresponding limiting holes 12. The other end of the snake bone body 10 is provided with two concave parts 13 corresponding to the extending parts 11, and the two concave parts 13 are provided with limiting bulges 14 corresponding to the limiting holes 12.

The central connecting line of the two limiting holes 12 is perpendicular to the central connecting line of the two limiting bulges 14. When the snake bone components are connected, the snake bone components can rotate in a staggered mode, and 360-degree rotation of the snake bone structure is further achieved.

An irregular first limiting plane 15 is arranged on the peripheral surface of the limiting protrusion 14, and a second limiting plane 16 matched with the first limiting plane 15 is arranged on the limiting hole 12. The snake bone component can be limited to the adjacent snake bone components after rotating a certain angle.

One end of the snake bone body 10 is provided with two relief parts 17, and the two relief parts 17 and the two extending parts 11 are arranged at intervals. In this embodiment, the relief portion is an arc portion that is recessed inwards along the axial direction of the snake bone body.

The cross-section of the two protrusions 11 is arcuate, and the opposite faces of the two protrusions 11 are planar. Correspondingly, the surface of the recess 13 opposite to the surface of the protrusion 11 is also flat, which facilitates the relative rotation between the two snake bone components.

The snake body 10 is made of a plastic material. In this embodiment, the snake bone body 10 is made of plastic with good biocompatibility, so that the snake bone structure has good flexibility and plasticity, which is beneficial to realizing the bending function of the snake bone structure.

As shown in fig. 10, the snake bone structure may be applied to an argon gas stylus that includes a stylus body 20 and a nozzle 30, and the snake bone structure is connected between the stylus body 20 and the nozzle 30.

When the argon gas knife pen is operated, external force acts on the snake bone structure, the snake bone component in the snake bone structure rotates up and down and left and right to change the shape, and the first limiting plane 15 of the limiting bulge 14 is matched with the second limiting plane 16 of the limiting hole 12, so that the snake bone structure can keep the bent shape. When the relative angle between the nozzle 30 and the pencil sharpener main body 20 needs to be changed, external force is applied to the snake bone structure again, so that the snake bone structure is bent into a corresponding shape and then is secondarily shaped, and the argon pencil sharpener can be used in tissues with narrow space when the pencil sharpener main body 20 is not inclined.

The foregoing detailed description of the preferred embodiments of the utility model has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
