An elastic block is provided at the bottom of the movable cavity, and the elastic block is provided with positioning teeth inserted into the positioning grooves.

[0007] After adopting the above structure, during the rotation of the lifting shaft, the elastic block is squeezed to make the positioning tooth withdraw from the positioning groove, and then the positioning tooth is inserted after aligning it with different positioning grooves, so that the rotation of the lifting shaft produces a sense of frustration, which helps to judge whether the corresponding storage tank is aligned with the feed pipe.

[0008] As a further improvement of the utility model, the top surface of the material tank base is provided with a downwardly recessed active cavity, the bottom end of the lifting shaft and the feed pipe are both arranged in the active cavity, and the material changing seat covers the cavity opening of the active cavity.

[0010] As a further improvement of the utility model, a clamping plate is provided on the side of the material storage tank, and the material changing seat is provided with a clamping groove matching the clamping plate, and the notch of the clamping groove is connected to the edge of the material changing seat.

[0011] After adopting the above structure, the slot is connected to the edge of the material changing seat through the notch of the card slot, and the card plate on the side of the storage tank is used to enter and exit the card slot to achieve quick insertion and removal of the storage tank, making it easy to replace empty storage tanks or storage tanks filled with different powders on the material changing seat.

[0012] As a further improvement of the present invention, the material changing seat is connected with an operating rod, and the axis of the operating rod corresponds to the radial direction of the lifting shaft.

[0013] After adopting the above structure, by arranging an operating rod corresponding to the radial direction of the lifting shaft on the material changing seat, the material changing seat can be lifted, placed and rotated more smoothly. BRIEF DESCRIPTION OF THE DRAWINGS
