Abstract:
1. A mixer comprising: a mixer body having a rotatable output shaft and a motor operatively coupled to the output shaft, the output shaft arranged to rotate around a shaft axis and orbit around another axis, the output shaft including a drive pin extending sidewardly therefrom and a retaining recess formed therein, the drive pin and the retaining recess on substantially diametrically opposed portions of the output shaft, a distance from a lower end of the output shaft to the drive pin is substantially the same as a distance from the lower end of the output shaft to the retaining recess; a mixing implement having a connecting portion with a shaft receiving opening having a drive pin receiving recess, a side opening located in the connecting portion and leading to the shaft receiving opening, and a retainer coupled to the mixing implement for movement along the side opening between an inward position in which at least part of said retainer is received in the retaining recess when the shaft is received in the shaft receiving opening to axially couple the mixing implement and the output shaft and a retracted position in which the retainer retracts from the retaining recess to permit separation of the output shaft and the mixing implement.
