ABSTRACT:
An adjustment apparatus of a reflection mirror is disclosed, the apparatus comprising a holding base plate, an affixing block affixed on the holding base plate, at least one adjusting set, and a rotatable chassis affixed onto the affixing block, wherein the reflection mirror is affixed on the rotatable chassis. Moreover, the adjusting set comprises an adjusting screw and an adjusting spring. The adjusting screw is mounted onto the holding base plate and transpierces the holding base plate to fix an extending portion of the rotatable chassis. The adjusting spring associated with the adjusting screw supports an extending portion of the rotatable chassis to counterbalance the adjustments in the adjusting screw. When the adjusting screw is rotated in, the rotatable chassis rotates along a first direction and compresses the adjusting spring. When the adjusting screw is rotated out, the rotatable chassis rotates along an opposite direction to the first direction and stretches the adjusting spring.
