• a securing element for rotatable mounting of a hand-part-side end section of the drive rod;
• and
• a bearing pin for positioning, securing and for an oscillatorily rotatable mounting of the brush head on the attachment brush housing,
• wherein:
• the bearing pin comprises a pin shank and a pin head with a diameter which is larger compared to the pin shank, and the pin shank towards the pin head comprises a first cylindrical section, and the pin shank towards a free end comprises a second fastening section with a structured surface,
