1. A lifting mechanism for a food processor, comprising:
a mounting platform;
a cutter shaft rotatably mounted relative to the mounting platform and axially movable along an axis of the cutter shaft relative to the mounting platform;
a drive sleeve defining an installation bore, the installation bore comprising an internal threaded structure, the cutter shaft being provided with an external threaded structure, the internal threaded structure being threadably engaged with the external threaded structure; and
a driving module operatively coupled to the cutter shaft and configured to drive the cutter shaft to rotate relative to the mounting platform;
wherein, when a rotational speed differential exists between the drive sleeve and the cutter shaft, the external threaded structure cooperates with the internal threaded structure to drive the cutter shaft to move along its axial direction.
