(21a, 21b) The hole is formed on the extension line, the shaft is fixed by a bolt 41a, and the rear upper end is inclined upwardly rearward, and the left and right side fastening holes 21a, 21b of the rear side horizontal fixing rod 20a are extended. Each of the upper bolt holes 41 are formed through holes on the line and are shaft-fixed by bolts 41a, and the front lower end portion is positioned to be inclined to the rear lower side, and the rear lower end portion is positioned to be inclined to the front lower side and overlapped with the front lower end portion. It has a bottom bolt hole 42 that is formed through a hole and is shaft-fixed by a bottom bolt 42a having a hook 42b, and has an upper long hole 43 in the longitudinal direction at the upper part, and the middle part in the longitudinal direction in the middle part. It has a long hole 44, a lower long hole 45 in the longitudinal direction at the bottom, an upper bolt hole 46 between the upper long hole 43 and the middle long hole 44, and a middle long hole 44 and Between the lower long hole (45), the front and rear left and right guide supports (40, 40a) (40b, 40c) having a lower bolt hole (47); and a plurality of rubber balls 53 having a spherical shape of an insulating rubber material in which a shaft hole 53a passing through the center is formed, and a plurality of rubber balls 53 are fitted at regular intervals through the shaft hole 53a at regular intervals to rotate the shaft. It has a merchant ball support bar 52 and is located in the upper, middle and lower portions between the front left and right guide supports 40 and 40a and the rear left and right guide supports 40b and 40c, respectively, so that the left and right cross sections of the ball support bar 52 are the upper and lower lower bolt holes ( 46, 47, 42 are respectively bolted to the upper and lower bolt holes 46 and 47, and the hook bolt 54 having a hook 54b formed on the front end surface of the bolt head 54a is bolted, and the front and rear left and right guide support bars ( 40, 40a) (40b, 40c) in the lower bolt hole 42 overlapped with the lower end, the lower bolt 42a having a hook 42b formed on the front end surface is fixed to the fixed ball support bar 51 is formed, respectively, It has a plurality of spherical rubber balls (56b) of insulating rubber material in which a shaft hole (56c) passing through the center is formed, and a plurality of rubber balls (56b) are fitted at regular intervals through the shaft hole (56c) in a straight line to form a bar shape that rotates. It has a ball support bar (56a) and is located in the upper, middle and lower portions between the front left and right guide supports (40, 40a) and the rear left and right guide supports (40b, 40c), respectively, so that the left and right cross sections of the ball support bar (56a) are upper middle and lower long holes (43, 44 and 45), respectively, the upper expansion ball support bar 56 having the expansion and contraction hook bolt 55 formed with the hook hook 55b on the front end surface of the bolt head 55a is formed, respectively, and the corrugated pipe 57aa ) with a spring body wrapped in a spring body, one end is hooked and fixed to the hook 55b of the expansion hook bolt 55, and the other end is hooked to the hook hook 54b of the hook bolt 54 and the hook hook 42b of the lower bolt 42a). Fixed expansion springs (57, 57a, 57b) are formed, respectively, a plurality of inlet passing through between the plurality of rubber balls (53) of the fixed ball support bar (51) and the plurality of rubber balls (56b) of the upper expansion ball support bar (56) Inlet extension folding type for apartment house distribution having upper and middle lower cable extension supports (50, 50a, 50b) for fixing and supporting the extension (60) in the upper and lower parts and left and right sides, respectively It's about the connector. The present invention provides an upper and middle lower cable extension support having a rubber ball that elastically supports the extension spring by the elasticity of the extension spring while pivoting on the upper left and right sides and the lower left and right sides, and the front and rear left and right guide supports supporting it from the left and right. The number can be expanded to the left and right, up and down, so there is an effect of greatly improving the expandability.
