[0041] The first gear 3011 meshes with the toothed gear ring 3012 to transmit power to the toothed gear ring 3012, driving it to rotate. When the toothed gear ring 3012 rotates, the connector 302 on the toothed gear ring 3012 rotates accordingly, while the connector 302 on the support body 1 remains fixed in position. Thus, the relative movement between the two connectors 302 allows the steel ropes connecting the two connectors 302 at each end to be wound around the flexible composite hose and the support column 203, thereby securing the flexible composite hose.

The two second gears 3013 are connected to the first gear 3011 via a conveyor belt 3015. When the toothed portion of the toothed gear ring 3012 rotates to the position of one of the second gears 3013, the other second gear 3013 remains engaged with the teeth of the toothed gear ring 3012. Similarly, when the toothed portion of the toothed gear ring 3012 rotates to the position of the first gear 3011, the two second gears 3013 can also drive the toothed gear ring 3012 to rotate.
