ABSTRACT:
The present invention discloses a device for fastening an integration rod to an inner wall of a housing in a projection optical system and for adjusting a horizontal position and a vertical position of the integration rod corresponding to the inner wall. The fastening/adjusting device includes a frame, a sheath, a first spring, a second spring, a first adjustable screw, and a second adjustable screw. The integration rod is disposed in the sheath, and the sheath is disposed between the frame and the inner wall. The first adjustable screw pushes forward the integration rod, so that the first spring is compressed. The second adjustable screw pushes forward the sheath, so that the second spring is compressed. Therefore, the horizontal and vertical position of the integration rod corresponding to the inner wall can be respectively adjusted by adjusting the first and second adjustable screw.
