Description

Technical Field

[0001] This utility model relates to the field of food processing machine technology, and in particular to an assembly structure for a food processing machine. Background Technology

[0002] A juicer is a machine that mechanically extracts juice from fruits or vegetables. It uses a lifting platform to move the juicing head up and down, extracting juice. Juicers typically have limit switches that are triggered when the lifting platform reaches its maximum position, cutting off the motor power and preventing overshoot. However, the lack of a guide structure for the lifting platform during movement makes it prone to lateral displacement, potentially preventing the limit switch from triggering. Furthermore, different sizes and shapes of juicers have different component installation methods, making them less universal and less practical.

[0003] Therefore, further improvements are necessary. Utility Model Content
