Claim:
1. An articulation type supporter, comprising: a base frame which is rotatably installed at a structure; a movable frame of which one end is connected to the base frame and a first hinge connection unit, and the other end rotates by receiving a guide of the first hinge connection unit; and a plurality of connection frames which are in series connected through a portion of the other end of the movable frame and a plurality of second hinge connection units which are arranged with a predetermined interval from the portion of the other end of the movable frame, wherein a supported is connected to the connection frames so as to mount a predetermined item on the top of an end portion of the last position, and the first hinge connection unit includes a brake unit which enables a free upward rotation motion of the movable frame and is configured to provide pressure in order for a downward rotation motion of the movable frame to be performed with respect to a previously set weight which is applied from the other end of the movable frame, wherein the brake unit comprises a first brake unit which includes: a central shaft which is installed passing through the base frame and the movable frame through a center of a horizontal hinge shaft; a fixing unit part which is configured to prevent the separation of the movable frame with respect to the base frame through both ends of the central shaft; a first ratchet wheel which is configured to prevent rotation at the central shaft corresponding to a slit; a first pole of which one end is hinge-connected to the base frame or an inner side of a hinge hub, and the other end elastically rotates by a first elastic member and is tooth-engaged with the first ratchet wheel through the slit when the other end of the movable frame rotates downward; and a first pressing unit part which is installed at the central shaft and provides pressure to both sides of the movable frame based on the support of the base frame.
