Collecting mechanism and semiconductor preparation fixing workbench

The utility model discloses a collection mechanism and a semiconductor preparation fixing workbench, and the collection mechanism comprises a preparation part which comprises a pedestal, a test assembly and an extraction assembly. The rotating part comprises a supporting assembly and a power assembly; the semiconductor preparation fixing workbench comprises a clamping part and four sets of table corners. And the clamping part comprises two groups of placing grooves, three groups of clamping plates and springs. The device has the beneficial effects that the preparation component is matched with the rotating component, substances in the test component are extracted through the extraction component, and the substances are stored in another container through the rotating component, so that a mechanical extraction process is realized, the extraction steps are simplified, and the extraction time is shortened; and personnel injury caused by many dangerous chemical reactions is avoided.
