The driving gear is evenly distributed with involute drive teeth along a circumference. A storage groove is formed between every two adjacent drive teeth. The driving gear includes an output hole in an axial direction, and an auger is arranged inside the output hole. A forming hole is defined between two adjacent drive teeth, and the forming hole penetrates into the output hole and the storage groove. The forming gear includes a base body, multiple involute sliding teeth and multiple reset springs, and the sliding teeth are evenly distributed on the peripheral side of the base body in a circumferential direction. The base body includes multiple sliding grooves in one-to-one correspondence with the sliding teeth, which are integrally formed with a slide block.
