A household electric, stand food mixer with a motor in a housing, a handle and removable beaters at one end, a bowl supporting base with a column for pivotally and removably supporting the other end of the housing and in this general structure there is provided an improved mixer locking structure to prevent pivoting of the housing under heavy beater loads that comprises an apertured plate fixed to the column with a cut-out for leveling means operable through the cut-out to adjust the horizontal housing position, fixed hook means extend below the housing through the apertured plate and a lock slider is movable into the column parallel to the plate to engage the hook and lock the housing to the column. The slider is actuated from outside the column and has plural steps or equivalent for selective hook engagement in cooperation with a selected leveling position whereby the housing is locked to the column on an automatically selected slider position as determined by the leveling to prevent upward housing rotation under heavy beater loads.
