A food mixer with a convenient changeable mixing bowl

Abstract

This utility model belongs to the field of food mixers, specifically relating to a food mixer with an easily replaceable mixing rack. It includes a frame, with a drive cover hinged to the upper end of the frame. A mounting cover is installed inside the drive cover via bearings. A hexagonal tube is fixedly connected inside the mounting cover, and a hexagonal shaft is slidably connected inside the hexagonal tube. A mixing rack is fixedly connected to the lower end of the hexagonal shaft, and a guide rod is fixedly connected to the upper end of the hexagonal shaft. This utility model, by adding a hexagonal tube, a snap-fit ​​seat, and a fixing tube inside the mounting cover, allows the hexagonal shaft to be inserted into the hexagonal tube of the mounting cover during use. Then, the snap-fit ​​seat is pushed by the elastic force of a spring to connect with the annular groove of the hexagonal shaft, thus installing the hexagonal shaft. When disassembly and replacement are required, simply pulling the mixing rack disengages the snap-fit ​​seat from the annular groove to release the restriction on the hexagonal shaft, thereby making the replacement of the mixing rack more convenient.
