The specific embodiment

Below in conjunction with accompanying drawing, embodiments of the invention are elaborated: the present embodiment is implemented take technical solution of the present invention under prerequisite, provided detailed embodiment, but protection scope of the present invention is not limited to following embodiment.

The shown in Figure 1 core device of opening, comprises the outrigger 7 that is roughly hemispherical Shell shape, is fixed on the cavity of outrigger 7 with the interior internal frame that equally roughly becomes hemisphere shelly 1; Described outrigger 7 incomplete hemispherical Shell, but comprise outwardly directed a plurality of non-touching cantilevers 70 from intermediate position; Be opened in the through hole 10 on internal frame 1, slide and to be located in the nail 2 in described through hole 10, the inner side of described nail 2 insert the medial and lateral of internal frame 1 and described cantilever 70 against; Be arranged on the gathering sill 4 of outrigger 7 peripheries, encircle the anchor ear 6 in gathering sill 4, described anchor ear 6 ends have the handle 5 of adjusting its length.

Below will launch to describe to each critical piece:

Referring to Fig. 2, described anchor ear 6 is anchor ear 6 common on existing market, and the end of anchor ear 6 has skewed slot, has and skewed slot meshed gears (being similar to worm and gear principle) on handle 5.Handle 5 lengthens only, has increased the length of rotary arm.

Referring to Fig. 3, described outrigger 7 preferred elastomeric metals, have outwardly directed four non-touching cantilevers 70 from intermediate position, form the roughly cavity with opening of hemisphere shelly.Return Fig. 1, each cantilever 70 accordingly with a nail outside of 2 against.Described nail 2 is metal material, and is along circumferencial direction equally distributed four.The outer end of described nail 2 has the outer face 20 of expansion, and nail 2 outside is arranged with the spring 3 that is compressive state, and one end of described spring 3 is resisted against the outer surface that outer face 20, the other end are resisted against internal frame 1.Due to the setting of Compress Spring 3, make each nail 2 keep the state of expansion relatively, be convenient within nut puts into internal frame 1.
