Mirror-case separated outer rear-vision mirror

The utility model provides an external rearview mirror of detachable mirror shell, which comprises a mirror shell and a lens, wherein, the mirror shell is divided into two parts, one part is a mirror shell main part for installing lens, and the other part is a shell cover. The shell cover and the mirror shell main part are detachably connected. The external rearview mirror with detachable mirror shell of the utility model divides the original mirror shell into the mirror shell main part and the shell cover. The shell cover can have different colors to match with the color of automobile, thereby reducing the stocking cost, saving storage space, reducing funding pressure and improving efficiency. Because the damage of rearview mirror occurs mainly in the shell cover, the rearview mirror with detachable mirror shell can change only the shell cover but not change the entire rearview mirror when the rearview mirror is damaged, thereby reducing burden of owners.
