A device capable of exchanging image projection directions includes an inner body (10) provided with an internal reflector (13) having adjustable angles and a horizontal light permeation aperture (15); an accomodation tube (16) is formed at the rear of the inner body (10) and an upper light permeation aperture (161) is formed at the top of the accomodation tube (16); an outer accomodation barrel (20) is disposed with at least two connection openings (22,24,26) at the outer periphery thereof; and an inner accomodation barrel (30) is disposed with a long orifice (32) and an outer connection opening (34), and is further flexibly connected into the outer accomodation barrel (20) and fixed around the accomodation tube (16), such that the long orifice (32) corresponds to the upper light permeation aperture (161) for forming a path for light beams. The connection openings are connected to binocular connection barrels (41,42,43) having various magnifications in advance, thereby viewing images with different magnifications and viewing ranges without dismantling or assembly of the binocular connection barrels. <IMAGE>
