In one embodiment, as shown in fig. 1 to 8, the fixing assembly 730 includes a fastener 732 and a positioning member 731. The positioning part 731 includes a third pressing surface formed to cooperate with the second pressing surface 602, and a second damping member 720 is disposed between the third pressing surface and the second pressing surface 602. The positioning member 731 further has a positioning and mounting through hole 7311, the connecting column 122 passes through the positioning and mounting through hole 7311, the fastening member 732 is a screw, a screw post of the screw extends into a screw hole on the connecting column 122, and when the screw is tightened, a screw cap presses and fixes the positioning member 731. Through increasing the positioning part 731, when the first connecting part 60 rotates, the positioning part 731 isolates the second damping part 720 from the screw cap and fixes the second damping part and the screw cap, so that the situation that the screw cap cannot be driven to rotate when the second damping part 720 rotates along with the rotation of the first connecting part 60 is avoided, the screw rotates along with the screw cap to be loosened, the situation that the whole pivoting structure cannot work normally is avoided, and the working reliability of the pivoting structure is improved.

By providing a routing channel, electrical connections are facilitated to pass through the pivot connection structure to provide power for operation of the power-consuming unit 80, such as a fan head. Therefore, the electric connection line is protected by the routing channel, so that the electric connection line can move in the loose routing channel due to the fact that the electric connection line is pulled in the vertical rotating process of the pivoting connection structure of the power utilization unit 80, if the routing channel is not arranged, the electric connection line is likely to be relatively close to other parts in the pulling process, and therefore friction of contact with other parts causes damage to the outer skin of the electric connection line, so that the power utilization unit 80 cannot normally work and risks of electric leakage are caused. The operational reliability and safety of the electrical connection lines for supplying power to the power consuming unit 80 are thus ensured by the above-described wire passing portions and wire routing channels.

Further, as shown in fig. 8, the second wall 607 and/or the third wall 608 are/is bent toward the center of the first wall 606, and the bent free ends are not in contact with each other, so as to form a wire passage for passing the electrical connection wire.

By further arranging the second wall bending part 611 and the third wall bending part 610 and forming the wire passing opening 609, the electric connection wire can be conveniently placed into the wire routing channel from the outside through the wire passing opening 609. The size of the wire through opening 609 is matched with the diameter of the electric connecting wire, if the electric connecting wire is generally 2mm, the wire through opening 609 can be set to be 1-2 times of the electric connecting wire, namely 4-8mm, so that the electric connecting wire is not easy to be separated from the wiring channel while passing through the wire through opening 609 conveniently.
