5. The intelligent cooker driving mechanism as claimed in claim 4, wherein the driving means is two hall motors, and the two hall motors drive one and the other of the two screw driving mechanisms, respectively.

6. The intelligent cooker as in claim 5 wherein one of the support shafts is connected to a station motor for driving the cooker assembly to rotate about the support shaft through a worm gear drive, and the other support shaft is provided with a station checking device for detecting the rotational position of the cooker assembly; the connecting piece is composed of two substrates which are separately arranged and have the same outline shape and structure, the two substrates are fixedly connected through bolts, the opposite surfaces of the two substrates are provided with an assembly worm wheel and a worm, the mounting position of the nut and a channel for the screw rod to pass through, or the opposite surfaces of the two substrates are provided with an assembly station detection device, the mounting position of the nut and a channel for the screw rod to pass through.

7. The intelligent cooker driving mechanism as claimed in claim 6, wherein the two substrates have opposite surfaces formed with circular grooves coaxial with the supporting shaft, and the supporting shaft has bearings on both sides of the worm wheel, each bearing being fitted in the corresponding circular groove.

8. The intelligent cooker driving mechanism as claimed in claim 7, wherein the station motor is a motor with a hall sensor; the station detection device comprises an annular mounting plate, a first travel switch fixedly connected to the mounting plate and located near the supporting shaft, and a first baffle fixedly connected to the supporting shaft and arranged along the radial direction of the supporting shaft in a protruding mode and used for touching the first travel switch to obtain a zero reference signal of the Hall sensor.

9. The intelligent cooker drive mechanism as claimed in claim 8, wherein a second and third travel switch are provided on the mounting plate adjacent the support shaft to limit the rotational position of the cooker assembly by actuation of the first stop.

10. The intelligent cooker driving mechanism as claimed in claim 9, wherein the four positioning pulleys are mounted two by two on the top and bottom sides of the base plate, and the shape enclosed by the four positioning pulleys is quadrilateral.
