ABSTRACT:
A dynamic showing rack mainly includes four main posts, each of which further includes a plurality of serially connected connecting posts, knuckles, and spindles. The knuckle has flat upper and lower sides, and a bearing mounted therein. The connecting post has two bevel end surfaces, and the spindle is extended through the bearing with two ends held in the bevel end surfaces of two connecting posts separately located at upper and lower sides of the knuckle, so that two connecting posts are obliquely extended from one knuckle in different directions. A motor is connected to the spindle in one of the lowest connecting posts to turn and swing the connecting post, and accordingly, all main posts of the rack to create a dynamic showing effect.
