A 2-1 rotation transmission gear meshed with the gear and a 2-2 rotation transmission gear meshed with the 2-2 power gear may be disposed.

This mechanism may be equally applied to the 2-2 gear unit 3200 ′, and as a result, the second gear unit 3200 ′ also has the first power transmission unit and the second power in parallel. It may be rotated by receiving rotational force from the transmission unit.

That is, as described above, the mechanism in which the motor rotation shaft transmits the rotational force to the first upper gear 3711 and the first lower gear 3721, the first upper gear 3711 and the first lower gear 3721 A mechanism for transmitting rotational force to the first power transmitting unit and the second power transmitting unit, the first power transmitting unit and the second power transmitting unit being the 2-1 gear unit 3100 ′ and the 2-2 second power transmitting unit The mechanism for transmitting the rotational force to the gear unit 3200' may be implemented by the above-described mechanism.

For example, an end of the cable bear 6000 may be connected to the cradle 1000 and interlocked with the elevating and lowering of the cradle 1000 to elevate and descend on the pole P.

A pulley (not shown) that is rotated by the positional movement of the cable bear 6000 may be disposed on the through hole F to facilitate elevating and lowering of the cable bear 6000 .

On the other hand, the pole system having the lifting and lowering function of the cradle is disposed in the height direction on the outer surface of the pole P, and forms an enclosure space S4 surrounding at least a portion of the cable bear 6000 exposed to the outside. to further include a guide part 7000 limiting the movement of the cable bear 6000 in the lateral direction.

For example, the guide part 7000 may be disposed to protrude along the height direction on the outer surface of the pole P on which the first rail part 2100 and the second rail part 2200 are not disposed. .

For example, the guide part 7000 may form the enclosure space S4 for accommodating the cable bear 6000, and the cable bear 6000 may move in the height direction on the enclosure space S4. The position movement is not limited, but the position movement in the lateral direction may be limited by the guide part 7000 .

For example, the guide part 7000 may be in the shape of a C-shaped steel as a whole.

For example, as the guide part 7000 protrudes on the outer surface of the pole P, it is possible to minimize the shaking of the pole P by the wind like the rail part 2000 .

In addition, as the guide part 7000 accommodates the cable bear 6000, it is possible to minimize shaking of the cable bear 6000 by the wind, and the pole P is moved by the cable bear 6000 It can prevent the coating from peeling off.

Accordingly, the intermediate unit 8000 may minimize damage to the cable bare 6000 or the holder 1000 by external force by mediating the connection between the cable bare 6000 and the holder 1000 .

For example, the intermediate part 8000 may be made of a material such as rubber or synthetic resin having elasticity, but is not limited thereto and may be a metal material.

On the other hand, the intermediate portion 8000 includes a first intermediate portion 8100 connected to the cable bare 6000 and a second intermediate portion 8100 that is bent from the first intermediate portion 8100 and connected to the cradle 1000 ( 8200) may be provided.
