[0009] Further preferably, the winding frame and the junction box are sealed by a sealed bearing, and a vertical rod is provided on the back of the winding frame for winding the wire.

[0010] The beneficial effects of the utility model are as follows: the spring pushes the metal plate to press against the cylindrical shape composed of the rotating block and the metal block; during the synchronous rotation of the rotating block and the metal block, the spring will not be compressed and the elastic force of the spring on the metal plate is always maintained, so that the contact between the metal plate and the metal block is stable, and the utility model has the advantage of stable wiring; the waterproof bearing is located between the rotating rod and the waterproof cover to prevent external air from entering the plastic shell through the gap between the rotating rod and the waterproof cover; the sealed bearing between the junction box and the winding frame prevents external air from entering the plastic shell through the gap between the junction box and the winding frame cover, so that the inside of the plastic shell is fully isolated from the outside world, and the components inside the plastic shell are prevented from being damp, and the utility model has good waterproof ability.
