Abstract
A fine-tuning structure of sensing element includes: a circuit board, on which sensing element is fixed and arranged; a lens set, which is bolted together with the said circuit board by bolt; it is characterized: an elastic element is arranged between the circuit board and the lens set; by the elastic element, there is an elastic expanding-and-contracting force provided between the circuit board and the lens set and, through the difference of depth for the bolt being bolted into the lens set, the distance between the sensing element and the lens and the obliqueness of the sensing element may be fine-tuned.
