摘要： A stand mixer comprising a drive shaft, a transmission shaft, and a coupling. The drive shaft is rotatably held in a first housing. The transmission shaft is held in a second housing. The second housing is pivotally mounted to the first housing so that the first housing may be pivoted relative to the second housing. The coupling connects the drive shaft to the transmission shaft when the first housing is in an operating position. The coupling includes a self aligning coupling. The self aligning coupling comprises a first member, a second member and a spring. The first member is inserted into and intermeshed with the second member to transfer power between the drive shaft and the transmission shaft. When the first housing is pivoted to the operating position the spring biases the first member against the second member to intermesh the first member with the second member.
