The utility model relates to a charging basket fixing device and a pressure plate pump device. The material
barrel fixing device comprises a first hoop and a second hoop. The first hoop is used for sleeving the
barrel body, the second hoop is used for sleeving the
flange, the second hoop sleeves the first hoop, and the first hoop and the second hoop define a limiting space for accommodating the
flange. During installation, the first hoop sleeves the
barrel body, the second hoop sleeves the
flange, meanwhile, the flange is located in the limiting space, and the end face of the first hoop limits the flange so as to limit the material barrel to move in the direction away from the supporting base. Thus, under the cooperation of the first hoop and the second hoop, the material barrel is fixed relative to the supporting base, the empty material barrel is prevented from moving up and down along with the pump body, an operator can conveniently and rapidly replace the material barrel, meanwhile, fingers are prevented from being squeezed when the operator manually replaces the material barrel, and the
operation safety is guaranteed. In addition, by arranging the first hoop, the structural strength of the material barrel fixing device can be improved through the first hoop, and deformation of the material barrel fixing device is prevented.
