Frame axle is fixedly connected on the bracket；Described spring, described positioning sliding axle, described rotary shaft sequentially pass through described support shaft
Install on the bracket, described positioning sliding axle is moved along the axial direction of described support shaft, and described rotary shaft is around described
The rotation of frame axle or the axial direction along described support shaft are moved and are rotated around described support shaft simultaneously；Described spacer pin is located in institute
State in perforate, be fastened on the other end relative with the one end being provided with prominent or groove in described rotary shaft, by described limit
Position pin limits described rotation axial side axial movement.
When rotary shaft rotates, the prominent or groove in rotary shaft promotes oriented sliding axle to move axially rearward and compress
Spring, when prominent in rotary shaft or when groove moves to groove or highlight on oriented sliding axle, spring promotes orientation to slide
Moving axis return, make prominent engage with groove, make rotary shaft in a certain specific position stopping it is achieved that the positioning of fixed angle.
It is preferred that described rotary shaft be provided with an extension arm in being provided with the relative other end in prominent one end, described stretch
It is provided with groove on long-armed, be stretched on the part of rotary shaft and described spacer pin for accommodating described support shaft, on described extension arm
Also open up hole.This structure can facilitate rotational structure and the part of required rotation to be connected, easily disassembled.
It is preferred that described projecting projects for dentation, corresponding described groove is tooth-like recesses, and dentation projects recessed with dentation
Groove is engaged, and can increase fixing stability.
It is preferred that in described rotary shaft or described positioning sliding axle on can be according to the different multiple described teeth of Demand Design
Shape groove, it is possible to achieve the positioning of multiple difference angles.
Compared to prior art, the present invention has advantages below：
The pivot structure that the present invention provides has location structure, can stop in a certain specific position, and stable fixation,
Achieve the position sense in rotation and position.By setting a series of fixed angle, it is possible to achieve the determining of multiple angle positions
Position.

Specific embodiment
Below embodiments of the invention are elaborated, the present embodiment is carried out under premised on technical solution of the present invention
Implement, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to following enforcements
Example.
Refer to Fig. 1-Fig. 5, the pivot structure in the present embodiment includes rotary shaft 1, positioning sliding axle 2, spring 3, spacing
Pin 4, support shaft 5 and support 6, one end of rotary shaft 1 is provided with prominent 11, positioning sliding axle 2 is provided with corresponding with prominent
Groove 21, support shaft 5 is provided with perforate corresponding with spacer pin.Wherein：Support shaft 5 is fixedly connected on the frame 6；Spring
3rd, positioning sliding axle 2, rotary shaft 1 sequentially pass through support shaft 5 and install on the frame 6, and prominent 11 are stuck in groove 21, and positioning is slided
Axle 2 can only be along the axially-movable of support shaft 5, and rotary shaft 1 can be also rotatable along the axially-movable of support shaft 5；Spacer pin 4 is located in
In perforate on support shaft 5, it is fastened on the other end relative with the one end being provided with prominent 11 or groove 21 of rotary shaft 1.
When rotary shaft 1 rotates, it is arranged on the prominent 11 promotion positioning sliding axles 2 in rotary shaft 1, makes positioning sliding axle 2
