Exposed electronic sensing element fixing device

The utility model provides an exposed electronic sensing element fixing device which at least comprises a mounting base and a pedestal. A miniature exposed electronic sensing element such as a photosensitive element and a touch switch conductor can be disposed and fixed in a fixing groove of an accommodation room in the mounting base, so that the miniature exposed electronic sensing element can be effectively fixed. In addition, the miniature exposed electronic sensing element can be rapidly and effectively fixed to a to-be-assembled object through the pedestal, and can be rapidly combined with the to-be-assembled object through the mounting base and the pedestal, and thus the miniature exposed electronic sensing element in the mounting base can be rapidly and effectively assembled in the object and can exert possible actuation functions, and effective application of the miniature exposed electronic sensing element can be realized.
