The outside of the existing elastic connecting piece is mostly a hose, the inside is a flexible shaft core, the strength of the flexible shaft core is not enough, the amplitude of the flexible shaft core is often not well controlled when the flexible shaft core is bent, and acting force cannot be well transferred. For some products which need to accurately control the bending amplitude (angle) in the using process, the using effect is often less ideal.
Therefore, the elastic connecting piece with high strength and controllable bending amplitude is needed to be provided.

The invention aims to provide a processing method of an elastic connecting piece, which solves the defects that the strength of the elastic connecting piece is not high and the bending amplitude is not easy to control in the prior art.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

s1, fixing a circular tube on a workbench, and cutting the circular tube by adopting laser to obtain a shell;
s2, placing the elastic piece in the shell to enable the elastic piece to be fixedly connected with the two ends of the outer shell, and obtaining the elastic connecting piece.
In the invention, the shell comprises an outer shell and end heads arranged at two ends of the outer shell; the outer shell is formed by connecting a plurality of connecting bodies; the connecting body comprises a main body and convex teeth arranged at two ends of the main body; a groove is formed between two adjacent convex teeth in each connecting body, so that the two adjacent connecting bodies are matched with the groove of the other connecting body through the convex teeth of one connecting body to realize connection; the end is provided with a convex tooth which is the same as the connecting body and is matched and connected with the groove of the connecting body through the convex tooth.
In some embodiments of the invention, the teeth comprise a connecting portion and a protruding portion; one end of the connecting part is connected with the main body of the connecting body, and the other end of the connecting part is connected with the protruding part.
Furthermore, the protruding parts of the protruding teeth are arranged in two numbers, and the two protruding parts are respectively arranged on two side walls of the end part of the connecting part. The arrangement makes the convex teeth similar to T-shaped, and the structure is simple.
In the invention, the convex teeth on the same end part of the main body of the connector are uniformly distributed, and the convex teeth on different end parts are symmetrically arranged at two ends of the main body. The convex teeth are uniformly distributed, so that different convex teeth of the connecting body are stressed the same, and the deflection angles of the elastic connecting piece bent towards different directions are the same.
In some embodiments of the present invention, two sidewalls of the protruding tooth connecting portion are disposed along a radial direction of the main body cylinder; the side wall of the convex tooth convex part is arranged along the radial direction of the main body cylinder. The connecting part of the convex tooth and the side wall of the bulge part are radially arranged to be combined with the connecting body to form a whole cylinder, and the convex teeth of the adjacent connecting bodies have a limiting effect, so that the connecting between the connecting bodies is more stable.
Furthermore, the joints of the side walls of the convex tooth convex parts and the top surface and the bottom surface are rounded. Therefore, the area of a local gap at the contact position between the convex teeth can be increased, the permeability is increased, and the connecting piece is more conveniently cleaned.
The invention can be further improved, and the height of the convex part of each convex tooth is smaller than the depth of the groove formed between two adjacent convex teeth. The arrangement enables the two adjacent connecting pieces to be stably connected through the matching of the convex teeth and the grooves, and meanwhile, the depth of the grooves can be adjusted to control the size of the angle between the two adjacent connecting pieces which is bent along the radial direction.
Further, the depth of the groove is set to be 1.5-2.0 times of the height of the convex part of the convex tooth.

Furthermore, the laser contact second entry point and the laser contact second exit point are points corresponding to the first convex tooth and the first convex tooth matching groove.
Preferably, the starting point and the end point of the second laser track are different points, the starting point and the end point of the second laser track are located on two sides of a connecting line between a laser contact second exit point and a laser contact second entry point, and the second laser track is a non-closed track.
