[0032] First, the pipe fittings are manually loaded into the positioning device of the perforated circular tube 21 and then the device is started. Since the bottom of the positioning device of the perforated circular tube 21 is the first inclined support structure and the second inclined support structure, the pipe fittings in the positioning device of the perforated circular tube 21 are placed and accumulated in the shape of a funnel inside the material. The circular tube 21 material distribution motor of the speed regulating and reducing motor 9 drives the toothed planetary gear 14 at the bottom of the positioning device of the perforated circular tube 21.
