Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, the utility model embodiment provides a kind of corrosion-resistant firm micromachine stretching shell attractive in appearance, it is wrapped
Include casing 100.
In the present embodiment, the casing 100 is formed in one structure, the drawn of casing 100, surface polishing and plating and
Into so that the surface smoothness height of casing 100, corrosion resistance and good, good mechanical property.
In the present embodiment, the casing 100 is in the form of a column, but simultaneously non-cylindrical.
With reference to shown in Fig. 1 and Fig. 2, the casing 100 has blind end 110 and openend 120, its axle in the casing 100
Upwards, the casing 100 is also including the first side between openend 120 and blind end 110, second side, the 3rd side
With the 4th side.
With reference to shown in Fig. 1 and Fig. 3, wherein, first side and the 3rd side are plane, and it is shaped as rectangle, the second side
Face and the 4th side are arc surface, and for first side between second side and the 4th side, the 3rd side also is located at the second side
