  • Patent number: 11872535
    Abstract: A connecting chuck of a material cylinder for a mixer and a mixer are disclosed according to the present application. The chuck includes a chuck body, and a first axial position-limiting connector and a second axial position-limiting connector are provided on the chuck body. After the chuck body rotates around the outlet pipe of the material cylinder by a preset angle, the first axial position-limiting connector can cooperate with a first axial position-limiting cooperating member on the material cylinder, and the second axial position-limiting connector can cooperate with a second axial position-limiting cooperating member on the mixer, so that an inlet pipe of the mixer is compressed with the outlet pipe of the material cylinder for cooperation. Through the above structure, after use, the chuck body reversely rotates to an initial position and the mixer is replaced, and the chuck body is reusable without replacement.
