The bottom end of the receiving plate 51 is fixedly connected to the top end of the bottom plate 6. The receiving plate 51 can be driven to move synchronously by moving the bottom plate 6. The left end of the receiving plate 51 is slidably connected to a fixing plate 52 for stabilizing the material barrel 4. The front end of the fixing plate 52 is provided with an inclined surface 53 for facilitating the material barrel 4 to be inserted into the fixing plate 52. When the inclined surface 53 is squeezed, the fixing plate 52 will be forced to move outward. The right end of the fixing plate 52 is fixedly connected to a fixing spring 54 for pushing the fixing plate 52 to move. The right end of the fixing spring 54 is fixedly connected to Connected to the inner wall of the storage plate 51, there are multiple groups of storage plates 51, fixed plates 52, inclined surfaces 53, and fixed springs 54. The multiple groups of storage plates 51, fixed plates 52, inclined surfaces 53, and fixed springs 54 are symmetrically arranged, so that the material barrel 4 can be fixed from both ends. The telescopic component 3 includes an outer tube 31 for accommodating the air hole sheet 32. The inner wall of the outer tube 31 is fixedly connected to the air hole sheet 32 ​​for creating an air pressure difference. The bottom end of the outer tube 31 is slidably connected to the inner tube 34 for slowing down the moving speed of the protective cover 23. The top end of the inner tube 34 is fixedly connected to the rubber plug 33 for sealing the air.

[0025] Reference Figure 1 - Figure 3 The outer wall piston of the rubber plug 33 is connected to the inner wall of the outer tube 31, and the rubber plug 33 can block the air leakage between the pore sheet 32 ​​and the inner tube 34. The top of the outer tube 31 is provided with an air hole 35 for circulating air, and the top of the pore sheet 32 ​​is provided with an air hole 26 for generating air pressure. The diameter of the air hole 35 is larger, the air flow rate is faster, and the descending rate of the inner tube 34 is faster. The diameter of the air hole 36 is smaller, the air flow rate is slower, and the descending rate of the inner tube 34 is slower. The outer wall of the telescopic shaft 22 is slidably connected with a stirring shaft 25 for connecting a stirring piece 26, the outer wall of the stirring shaft 25 is fixedly connected with a circular plate 24 for connecting a protective cover 23, the outer wall of the circular plate 24 is rotatably connected with a protective cover 23 for preventing powder from flying, the bottom end of the stirring shaft 25 is fixedly connected with a stirring piece 26 for stirring powder materials, and the inner wall of the circular plate 24 is slidably connected with a sliding block 27 for fixing the movement of the stirring shaft 25.

[0026] Reference Figure 1 - Figure 3The outer wall of the telescopic shaft 22 is provided with a groove 210 for clamping the sliding block 27, and the sliding block 27 is adapted to the groove 210. There are two groups of grooves 210, respectively at the top and bottom ends of the outer wall of the telescopic shaft 22. The front end of the sliding block 27 is fixedly connected with a sliding spring 29 for pushing the sliding block 27 to move. The front end of the sliding spring 29 is fixedly connected to the inside of the circular plate 24. When the sliding spring 29 is relaxed, the sliding block 27 is in the initial position. At this time, the slider will be connected to the telescopic shaft 22, the stirring shaft 25, and the protective cover 23 at the same time. At this time, the telescopic shaft 22, the stirring shaft 25, and the protective cover 23 will be fixed and cannot move relative to each other. The outer wall of the sliding block 27 passes through and slides on the top of the stirring shaft 25. The top of the sliding block 27 is fixedly connected with a dial block 28 for toggling the sliding block 27. When the dial block 28 toggles the sliding block 27 to move toward the circular plate 24 until it is out of the groove 210, the telescopic shaft 22 and the stirring shaft 25 are released from fixation.

[0027] Working principle: When placing the whole device, first move the shift block 28 to drive the sliding block 27 to move, until the sliding block 27 is out of the groove 210, the fixation between the stirring shaft 25 and the telescopic shaft 22 will be released, and then the shift block 28 can be loosened, and the stirring shaft 25 and the circular plate 24 will move downward under the influence of gravity. At the same time, the protective cover 23 fixed to the circular plate 24 will also slide downward synchronously. At this time, when the protective cover 23 moves downward, it will pull the inner tube 34 to move downward, so that the rubber plug 33 moves downward inside the outer tube 31, and at the same time, it will drive the air outside the outer tube 31 to pass through the air filter. Hole 1 35 enters the interior of the outer tube 31 until the air at the top of the pore sheet 32 ​​is filled. When passing through the pore sheet 32, the air flow rate is slowed down due to the smaller diameter of hole 2 36, so that the rubber plug 33 and the inner tube 34 move slowly downward until the stirring shaft 25 moves to the outer wall of the bottom end of the telescopic shaft 22. The sliding spring 29 pushes the sliding block 27 to re-enter the groove 210, so that the stirring shaft 25 and the telescopic shaft 22 are re-fixed. At the same time, the protective cover 23 will cover the top of the material barrel 4, thereby preventing the powder material from flying and achieving the effect of reducing material loss.

[0028] When the operator places the material barrel 4 on the top of the bottom plate 6, the operator first pushes the material barrel 4 to squeeze the inclined surface 53 in front of the fixing plate 52, so that the fixing plate 52 shrinks toward the inside of the storage plate 51 until the material barrel 4 is completely stuck between the fixing plates 52, so that the fixing plates 52 firmly fix the material barrel 4, thereby immediately fixing the material barrel 4 and preventing the material barrel 4 from moving left and right.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
