The lower clutch sleeve 13 can be respectively fixed at three positions of an upper position, a middle position and a lower position from the top of the washing machine to the lower direction under the action of the peripheral clutch finger, as shown in three positions I, II and III in figure 9. The clutch pusher dog adjusts the position of the lower clutch sleeve 13 under the action of the tractor, so that the outer clutch sleeve 1303 and the inner clutch sleeve 1301 are respectively positioned at different positions, thereby controlling the relation among the three shafts of the input shaft 1, the intermediate shaft 15 and the clutch shaft 2, and adjusting the position relation between the upper clutch sleeve 10 and the notch meshing pair 14 through the control system, so as to realize the meshing or the separation of the dewatering shaft 4 and the drainage shaft 5, and finally realize the control corresponding to different working conditions of the washing machine. The outer clutch sleeve 1303 can be fixed at three positions along the axial direction, and the inner clutch sleeve 1301 can be fixed at two positions along the axial direction. The inner clutch sleeve 1301 and the outer clutch sleeve 1303 are mutually matched under the control of the clutch pulling claw, three position structures of I, II and III shown in fig. 9 can be formed, the upper clutch sleeve 10 and the notch meshing pair 14 are positioned at an upper position and a lower position under the action of a control system or the clutch pulling claw, and different working conditions of the washing machine are realized according to the double clutch action.

Since the fixed sleeve 16 is fixed, the second engaging tooth B2' at the lower end of the fixed sleeve 16 is engaged with the seventh engaging tooth B2 at the upper end of the outer clutch sleeve 1303, and the outer clutch sleeve 1303 is fixed at this time; because the second spline at the lower end of the clutch shaft 2 is meshed with the fourth spline D1 on the inner side wall of the outer clutch sleeve 1303, the clutch shaft 2 is fixed under the action of the outer clutch sleeve 1303. The first meshing teeth at the lower end of the clutch shaft 2 are meshed with the fifth upper meshing teeth A2 at the upper end of the inner clutch sleeve 1301, so that the inner clutch sleeve 1301 is fixed; since the first spline at the lower end of the intermediate shaft 15 is engaged with the third spline C1 at the inner side wall of the inner clutch housing 1301, the intermediate shaft 15 is fixed by the inner clutch housing 1301.

The movable sleeve 17 is fixed with the input shaft 1, and the intermediate shaft 15 is kept in a free state due to the separation of the third meshing tooth A1' on the movable sleeve 17 from the sixth meshing tooth B1 of the outer clutch sleeve 1303.
Since the first engaging tooth at the lower end of the clutch shaft 2 is separated from the fifth engaging tooth A2 at the upper end of the inner clutch sleeve 1301, the inner clutch sleeve 1301 and the outer clutch sleeve 1303 are relatively independent. I.e. the clutch shaft 2 remains relatively independent from the intermediate shaft 15.
The movable sleeve 17 is fixed with the input shaft 1, and the inner clutch sleeve 1301 is fixed with the input shaft 1 because the third meshing tooth A1' on the movable sleeve 17 is meshed with the four meshing teeth A1 at the lower end of the inner clutch sleeve 1301; since the first spline at the lower end of the intermediate shaft 15 is engaged with the third spline C1 on the inner side wall of the inner clutch housing 1301, the intermediate shaft 15 is fixed to the input shaft 1 by the inner clutch housing 1301. That is, at this time, the clutch shaft 2 is fixed by the fixing sleeve 16, the intermediate shaft 15 is fixed to the input shaft 1, the clutch shaft 2 is independent of the intermediate shaft 15 and the input shaft 1 fixed to each other, the intermediate shaft 15 rotates in engagement with the input shaft 1, and the clutch shaft 2 is fixed.
At this time, the upper clutch cover 10 is also in an upper position, and the drain shaft 5 is engaged with the dewatering shaft 4 by a sliding key or a gear under the action of the upper clutch cover 10. When the input shaft 1 rotates, an input gear at the top end of the input shaft 1 is meshed with the upper planet gear, so that the planet carrier 11 and the impeller shaft 6 are driven to rotate in the same direction, the impeller shaft 6 finally rotates under the power action of the input shaft 1, and only the impeller in the washing machine moves under the action of the impeller shaft 6 at the moment, so that washing is realized.
