In the embodiment, the rotating shaft mainly comprises connecting components, and when the connecting components are assembled, the connecting components are parallel to each other and are arranged in a staggered manner, and the circular through holes of the connecting components are aligned with the track-shaped through holes of the left and right adjacent connecting components; as shown in fig. 4, when assembling, two adjacent connecting assemblies are parallel to each other and are arranged in a staggered manner, and the circular through hole of one connecting assembly is aligned with the racetrack-shaped through hole of the adjacent connecting assembly and is connected in sequence to form a rotating shaft.

Inserting a connecting shaft into the circular through hole of the connecting assembly and penetrating through the runway-shaped through holes of the adjacent connecting assemblies, wherein the connecting shaft is fixed in the circular through hole and can slide in the runway-shaped through hole one by one; the fixed shaft is arranged in the semicircular notch of the connecting piece and is fixed on the two connecting components at the left and right outermost sides.

In this embodiment, the connecting assembly is cut from one complete piece of steel or stamped from several pieces of steel. As shown in fig. 4, the connecting assembly is a schematic view of a rotating shaft formed by punching three steel sheets. The rigidity of the connecting component can be improved and the reliability of the rotating shaft can be improved by cutting and manufacturing the connecting component by using a complete steel sheet; the connecting component can be manufactured by stamping a plurality of steel sheets, so that the manufacturing cost of the connecting component can be reduced, the middle steel sheet can be replaced by components made of other materials during stamping manufacturing, or the middle space is filled in an injection molding mode, so that the weight of the connecting component is reduced, and the cost of the connecting component is reduced.

The structure that the wavy bulges are arranged in the runway-shaped through hole in the embodiment is used for realizing adjustment of multiple angles, and when the connecting shaft slides in the runway-shaped through hole, the connecting shaft is mutually rubbed and embedded with the wavy structure, so that stable stop of multiple positions of the rotating shaft in the runway-shaped through hole is realized. The preferred material of wave structure is rubber, and rubber possesses good deformability, possesses wear-resisting and can provide the big characteristic of frictional force again simultaneously, therefore, the wave structure in the runway shape through-hole can select rubber to make.

In the embodiment, the interface width of the connecting shaft is the same as the height above and below the racetrack-shaped through hole, and the shape of the connecting shaft comprises a circular shaft and a shaft formed by symmetrically cutting the circular shaft; the fixed shaft is a circular shaft or a semicircular shaft; the radius of the fixed shaft is less than or equal to that of the semicircular notch.

During assembly, the connecting assembly is aligned with the circular through hole and the runway-shaped through hole on the adjacent connecting assembly, and the connection of the two adjacent connecting assemblies is realized by connecting and drawing through the circular through hole and the runway-shaped through hole; the advantage of adopting the round shaft is that when the connecting shaft enters the wave trough of the next wave from the wave trough of one wave, the feedback feeling generated by the rotating shaft is more obvious, and the feeling of sliding the connecting shaft once in the through hole of the runway bear is more obvious; the shaft formed by cutting the circular shaft symmetrically has the advantages that the upper surface and the lower surface of the circular shaft are respectively cut, so that the contact surface between the upper surface and the lower surface of the circular shaft and the wavy structure in the runway-shaped through hole is increased, the friction area is increased, and the staying stability of the rotating shaft at an angle is enhanced when the rotating shaft rotates.

In this embodiment, the fixing shaft is disposed in the semicircular recess of the connecting assembly, and the fixing shaft is also inserted through all the connecting assemblies disposed on the left and right sides and fixed in the semicircular recesses of the connecting assemblies on the left and right sides, and the connecting assembly in the middle is not fixed with the fixing shaft and rotates relative to the fixing shaft when the rotating shaft rotates. The fixed shaft has the effect that when the connecting assemblies arranged in a staggered mode in the front, back, left and right directions rotate in the direction of the fixed shaft through the fixed shaft in the rotating process of the rotating shaft, the adjacent two connecting assemblies rotate around the fixed shaft, and the arc length of the adjacent two connecting assemblies on the side of the fixed shaft is prevented from changing in the rotating process.

In other embodiments, the semicircular notches may be disposed at some special positions to achieve additional effects, for example, the semicircular notches may be disposed at two ends of the quartering points of the connecting assemblies, when the semicircular notches are disposed at two end points of the quartering points, during assembly, the front and rear adjacent connecting assemblies may achieve mutual engagement of the sawtooth structures at the two ends in the flattened state, when the front and rear connecting assemblies are flattened and engaged with each other, the expansion angles of the front and rear connecting pieces reach the maximum value, and the reverse folding condition does not occur, which further plays a role in limiting the two connecting pieces in the flattened state.

In this embodiment, after the assembly is completed, when the rotating shaft moves, the connecting shafts fixed in the circular through holes of the left and right adjacent connecting assemblies slide back and forth between the two ends of the racetrack-shaped through hole. When the rotation angle of the rotating shaft is reduced, namely the rotating shaft is folded, the connecting shaft slides outwards in the runway-shaped through hole; when the rotation angle of the rotating shaft is increased, namely, when the rotating shaft is unfolded, the connecting shaft slides inwards in the runway-shaped through hole.
