Abstract
A head module capable of reciprocal rotation for an electric cleaning apparatus comprises cleaning elements, a housing and a driven rod disposed in a hollow inner cavity of the housing, wherein the rod is provided with a hollow cavity body for accommodating a drive shaft; at least one gap is provided in a region surrounding the hollow cavity body; at least one inner side notch is distributed on a side wall of the inner cavity, for accommodating a protrusion; the rod further comprises a partially cylindrical or conical cavity body region. When the drive shaft is not yet inserted into the rod, there is a gap between the notch and the protrusion in a direction perpendicular to the rotation axis (L) of the drive shaft. The length of the gap is greater than or equal to the amount of single-side interference between the rod and the drive shaft.
