[0036] In this embodiment, after the vibration motor 5 is started, the screen plate 4 installed on the shell 3 generates high-frequency vibration, effectively separating powders of different particle sizes. The powder on the screen plate 4 is classified by passing through the screen holes during vibration. The powder that meets the requirements passes through the screen holes into the collection box 2, and the powder that does not meet the requirements is screened into the waste box 30.

The positioning groove 19 and the positioning block 20 in the clamping sleeve 8 further increase the stability of the installation, avoid loosening or misplacement during vibration, and thereby ensure the reliability of the installation of the screen plate 4.
