The beneficial effects of the utility model are：
Compared with conventional art, the upper annular grid of the utility model is by semi-circular grid one and semi-circular grid 2 two
It is grouped as, upper annular grid and lower annular grid are identical structure, and semi-circular grid one and annular grid two are between the two
Distance can be adjusted by twisting the movement of adjusting screw nut, be just easier when dismounting in this way.
Compared with conventional art, the utility model roll adjustment strut is matched with strut hole, ladder type positioning runner and location supporting rod
One matching and the matching of camber positioning runner and location supporting rod two ensure that both semi-circular grid one and annular grid two
Between connection and the stabilization apart from adjusting.
One end is provided in strut hole to realize the spring that abut with roll adjustment strut, can be in this way when twisting adjusting screw nut
By the elastic force of spring and can be relatively labor-saving, while when assembling, the active force of spring or contact be acted on by annular grid
In group, so as to have mutual active force between the annular fastening spring in contact group, entire Mume flower contact is effectively raised
Stability；Adjusting screw nut is octagonal shape adjusting screw nut.It precisely easily carries out twisting adjusting in this way.
Description of the drawings
Fig. 1 is the sectional axonometric drawing of the utility model annular grid；
Fig. 2 is the stereogram of the utility model.
Specific embodiment
The utility model is being further elaborated with reference to attached drawing.
It please refers to Fig.1, Fig. 2, the utility model provides a kind of Mume flower contact of the tight shape spring of annular easy to disassemble, including packet
Including annular grid, support shaft 1, contact group 2 and annular fastening spring 3, annular grid is upper annular grid 4 and lower annular grid 5,
Upper annular grid 4 and lower annular grid 5 are interconnected and fixed by support shaft 1, upper annular grid 4 and lower 5 outside of annular grid
Several open slots 6 are respectively equipped with, contact group 2 is corresponded in construction opening slot 6, and the both ends in 2 outside of contact group are equipped with spring groove 7 and pacify
Equipped with annular fastening spring 3；The upper annular grid 4 is made of semi-circular grid 1 and 29 two parts of semi-circular grid, institute
It is identical structure to state annular grid 4 and lower annular grid 5；The semi-circular grid 1 is corresponding with semi-circular grid 29
