One end portion of the tilting unit is rotatably coupled to the main frame, the other end portion of the tilting unit is rotatably coupled to the first supporting frame to adjust a tilt angle of the first supporting frame with respect to the main frame and is detachable to be adjustably positioned along a length direction of the first supporting unit. The easel can adjust a tilt angle as desired and reliably maintain an adjusted tilt angle.
