Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
The embodiments of the present invention is related to a kind of housing structure of low cost, as shown in Figs 1-4, including 1 He of cylinder body
The outside of cylinder sleeve 2 is arranged in cylinder sleeve 2, the cylinder body 1, and the lower end of the cylinder sleeve 2 is flushed with cylinder body 1, the upper end of the cylinder sleeve 2
