The invention provides an integral column adjustable device; the integral column adjustable device and an integral column are commonly arranged on a light engine shell which leads the integral column to carry out the position adjustment in the first direction and the second direction; the adjustable device comprises two elastic parts which respectively provide elastic recovery forces opposite to the first direction and the second direction, two top-pushing parts which are respectively arranged at the opposite sides of the integral columns corresponding to the elastic parts; the two top-pushing parts are respectively provided with a contact surface; two top-pushing parts can move along the same operation direction and respectively apply the positive forces which can lead the integral column to move in the first direction and the second direction; the two top-pushing parts which can move in the same operation direction are matched with the two elastic parts so as to lead the integral column to move respectively in the first direction and the second direction, thus achieving the object that the two-dimensional position of the integral column can be adjusted by the same operation direction.
