Publication number: 20070002684Abstract: A means for connecting a driving shaft and a mixing paddle of a mixer including a driving shaft, a spindle of the mixing paddle and a clamping means, in which the clamping means comprises a clamping member and a locking member. The clamping member comprises a chamber for receiving the spindle of the mixing paddle, and at least one oblique surface extending along the direction of the spindle. The locking member engages between the oblique surface and the spindle. The clamping means further includes a rotation restricting means for restricting the relative rotation between the spindle and the driving shaft. With this structure, the connecting means is simple, reliable and can be easily operated without auxiliary tools. In fact, an operator may remove and attach the mixing paddle to the driving shaft without auxiliary tools.Type: ApplicationFiled: June 28, 2006Publication date: January 4, 2007Applicant: NANJING CHERVON INDUSTRY CO., LTD.Inventor: Youjun Dai
