The specific implementation of the gearbox is as follows: firstly, the four transmission shafts 37 extend out of the inner ring gear support ring 42 and are respectively contacted with a front circular plate, at this time, the input shaft 1 drives the output shaft 12 to rotate after being transmitted by the four transmission shafts 37, and the rotating speed of the output shaft 12 is the same as that of the input shaft 1; the switching block 21 is adjusted, firstly, the transmission shaft 37 in the first transmission unit 9 is completely pulled into the inner ring teeth 18, the input shaft 1 is in contact friction with the inner ring teeth support ring 42, the inner ring teeth 18 drive the sliding teeth 29 to rotate through the intermediate teeth 25, and then the transmission shaft 37 is driven to rotate, so that first-stage speed increasing is realized, then the switching block 21 is continuously adjusted, the transmission shaft 37 in the second transmission unit 9 is completely pulled into the inner ring teeth 18, the input shaft 1 is in contact friction with the inner ring teeth support ring 42, second-stage speed increasing is realized, the width of the sliding teeth 29 is very wide in the moving process, so that the sliding teeth cannot be separated from the intermediate teeth 25, and then the switching block 21 is continuously moved to realize third-stage and. The speed increasing is obtained by connecting four transmission units 9 in series, so that the transmission ratio range is high, and the use value is high.
