The objective of the present invention is not only to minimize a unit packaging area but also to improve structural stability by configuring assembly in a fitting method, by fixing the whole components through assembling based on a body part. For this, the body part includes: a first body (110) where the body unit (10) has first corners (112) which erect at each corner with a fixed height and have a first protrusion (1122) inwards, a first insertion groove (113) formed with a fixed depth at both ends of the first corner, a first protruded piece (118) which has a first insertion hole (119) formed inside and has a certain height at a center thereof, and at least one mounting protrusion (117) on an outer circumference; a circuit board (120) which is formed in the inside of the first body (110) and is constituted with a circuit; a second body (130) which is inserted into the first corner (112) of the first body (110), and includes a first plane (132), a first interval maintaining wall (134) standing at a frame of the first plane (132) with a fixed height, and a second boss (138) having a fourth insertion groove (139) formed for one end of the first protruded piece (118) of the first body (110) to be inserted into the first plane (132); and a finishing cap (140) which is located on an outer circumference of the second body (130), and forms a second plane (142) and a second corner (144) comprising a hooking protrusion (147) which stands at the corner of the second plane (142) with a fixed height and is hooked to the first protrusion (1122) of the first body. |
