The multifunctional soymilk machine as claimed in claim 1, characterized in that: the output shaft of the motor rotates clockwise, the screw rod part is in left-handed thread connection with the connecting screw hole, and the driving teeth and the driven teeth are unidirectional teeth in clockwise unidirectional transmission; each pressing blade is positioned on the left-handed spiral line.

3. The multifunctional soymilk machine as claimed in claim 2, characterized in that: the lower end face of the connecting blade faces the oblique lower side in the clockwise direction, and the inclination angle of the connecting blade is smaller than that of the pressing blade.

4. The multifunctional soymilk machine as claimed in claim 1, 2 or 3, characterized in that: the upper end of the rotary rod body is rotatably connected with a screw-out rod through a pin shaft, and a side containing groove for containing the screw-out rod is formed in the side face of the upper part of the rotary rod body; the rotating-out rod is rotated into the side containing groove in the juicing process, the rotating-out rod is unfolded to rotate the pressing mechanism down from the output shaft of the motor after the use is finished, and the motor reversely rotates at the speed of 0.2-1 revolution per second when the pressing mechanism is rotated down.

5. The multifunctional soymilk machine as claimed in claim 1, characterized in that: the included angle between conical surface and the horizontal direction is 2-5 degrees, the outer end of arc rib is towards the counter-clockwise bending.

6. The multifunctional soymilk machine as claimed in claim 1, characterized in that: a cup handle is formed on the side wall of the cup body, a power supply interface is arranged below the cup handle on the side wall of the cup body, a control panel is arranged at a position, far away from the cup handle, of the side wall of the cup body, a control circuit board is arranged in the control panel, and the motor, the heater and the power supply interface are respectively and electrically connected with the control circuit board; the control panel is also provided with a control button a for controlling the motor to rotate clockwise for work, a control button b for controlling the heater to work and a control button c for controlling the motor to rotate anticlockwise so as to be convenient for detaching the material pressing mechanism.

7. The multifunctional soymilk machine as claimed in claim 1, characterized in that: the diameters of the lower grinding disc, the upper grinding disc a and the upper grinding disc b are 10-16 cm.
