Abstract
The present invention relates to the field of food processing equipment, and more specifically to a lifting mechanism for a food processor. The mechanism comprises a mounting platform; a cutter shaft rotatable and axially movable relative to the platform; a drive sleeve with an internal threaded structure; an external threaded structure on the cutter shaft in threaded engagement with the drive sleeve; and a driving module configured to rotate the cutter shaft. When a rotational speed difference exists between the drive sleeve and the cutter shaft, the threaded engagement causes axial movement of the cutter shaft. This design employs a single driving module to achieve both rotation and lifting, thereby reducing structural complexity and manufacturing costs.
