摘要

The present invention relates to an arm module coupled to a lamp post or an electric post which is easily installed and conveniently repaired, and is capable of conveniently adjusting an illuminating angle of a lamp post or a closed circuit television (CCTV) camera, and more specifically, to an arm module which includes a support plate fixed by coming into contact with the upper end of a post such as a lamp post or an electric post; a coupling band fixing the support plate to the post; and an arm having an end coupled to the support plate, wherein (A) the support plate includes 1) a base portion having one surface contacting the post; and 2) both supporting wings vertically installed at the other surface of the base portion by being apart in an interval corresponding to the cross-section size of the arm, whereby the both supporting wings include rotary shaft holes facing each other at a portion adjacent to the base portion, and support holes facing each other and formed on a concentric circle of a predetermined distance with respect to the rotary shaft holes; (B) the arm includes a rotary hole corresponding to the rotary shaft holes formed at a portion adjacent to one end; and a fixing hole corresponding to the support holes formed while being apart from the rotary hole in a predetermined distance; and (C) the arm module further includes, when one end of the arm is inserted between the both supporting wings, 1) a rotary support shaft penetrating and supporting the rotary shaft holes of the support plate and the rotary hole of the arm; and 2) a fixing shaft penetrating and fixing the fixing hole of the arm and predetermined support holes of the support wings.
